More Photos, Less Text

Evidence of previous fires can be seen all over the park.

This tree has cancer... or at least that one part thinks it is a few hundred years old whereas the rest of the tree knows it's only about 50.
Found a tree which had exploded for no apparent reason.


Methods & Materials

I know you're all incredibly curious as to what exactly our research consists of, what I mean when I say "sampling plots". So I have chosen to use a series of photos of our equipment to describe just exactly what data we are collected and how we measure it, and then I'll explain the overall context and goals of the project.
Pictured left are our park radio and GPS. We utilize the GPS to locate the locations of the plots, usually hiking or driving near the location and then navigating via GPS to the exact (or fairly close) location. The park radio connects us to the rest of the park staff, allowing us to hear the goings on in the park and to radio in if we are in need of assistance. So far it has proven useful for hearing the weather forcast and we used it to assure a campsite at Manzanita before moving camp. It has also been entertaining at times to hear the goings-on of the park.

To the right are the first things we use when we reach the location. Immediately staking the centerpoint, we then work from that point for the rest of the plot. The two 50 m tapes are used to set up the plot and to measure slope. Next we have the clinometer and, of course, the compass. The clinometer is a neat device for measuring angles and heights. Using one of the 50 m tapes, we measure 20 m downslope of the stake, and use the clinometer to measure the slope angle. The compass gives us aspect of the slope, and we then use it to set up the north-south diameter line. The plots are 500 square meters, which entails a 12.61 m radius circle, so we run the tape out that far both north and south of the stake, giving us a 25.2 m working diameter.

The papers we use to record all the data are shown, filled in, at the top on the right. Under them is our permit to do field work for scientific research next to some of the USGS topographic quads of the area. Odd fun fact about topo quads as per Andrew: the green areas on the map are not just forested areas; they are areas of forest dense enough to hide a platoon of soldiers. Apparently the DoD funded the mapping project, and that is what they were interested in. As you can see from the papers, for each tree in the plot we measure several variables. The trees species, DBH, crown position, status, height, height to dead and live canopies, and live crown percentage estimate. The species is recorded as the abbreviated scientific name, for example Ponderosa Pine is Pinus Ponderosa is Pipo. Not so simple is White Fir, Abies Concolor, or Abco. Pinus Lambertiana, Pila, signifies Sugar Pine; Red Fir, Abies Magnifica, Abma; Douglas Fir, Pseudotsuga menziesii, Psme; Jeffery Pine, Pinus Jefferyi, Pije; Western White Pine, Pinus Monticola, Pimo; Incense Cedar, Calocedrus Decurrens, Cade.
Pictured to the right are our main measurement tools. The orange item is the DBH tape, measuring the trees diameter by circumference. That's right, you simply measure the circumferance of the tree at chest height, and the units are so altered that they display diameter. The opposite side is a simple meter tape for measuring heights to dead and live crown base on trees where you can reach the bottom of the crown. The yellow digital instrument next to the diameter tape is called a hypsometer. The device includes a laser rangefinder, so you do not need to be exactly 15 or 20 meters away as is the case with the clinometer. Simply shoot the bottom of the tree and the top and it gives you the height. The white book is a photo series book for approximating surface fuels per acre, as seen on the reverse side of the sheet. Finally, we take two types of photos of the plots. The camera on the right actually uses old-school film, and we use it to capture hemispherical photos of canopy cover. The white bubble-level on top of the camera case lets one know the camera is pointed directly upward, and the special lense on the camera captures an entire hemispherical photo, all 180 degrees of the sky and canopy cover. These photos will be digitized from the negatives and a program will analyze them to determine percent of canopy cover. Lastly, the DSLR on the left captures digital images north, south, east, and west of the center stake.

We have to get out of Starbucks soon, as I've been typing for what seems like hours, but I will give a brief description of the overall point of collecting all this data first. The main concern of the project is creating a canopy fuels map. This map will be added as a layer to several other layers of the forest fire GIS. Canopy fuels are extremely important in determining the dynamics of forest fire for a type of forest. The layer will be used to simulate fires under a number of different conditions: elevation, slope, aspect, tree species, dead and live canopy base height; all these variables play a role in fire tree mortality and the ability for a surface fire to develop into a crown fire. By sampling plots all over the park, Andrew will come away with an extensive set of data for a wide variety of different forest conditions. The plots we are sampling were sampled by Calvin Farris, fire ecologist with the NPS, about 10 years ago for a surface fuels map. We are completing the photo series interpretation of surface fuels to compare the changes which have occured over the past ten years, however this is not quite as accurate as the study he did which included browns transects. The canopy fuels map layer Andrew creates will be added to the surface fuels layer, as well as elevation data and several other layers, before being "burned" in a simulator under a number of different scenarios. For now, that's the best I can do, more on this and what exactly a fire adapted forest is later.

Week in Review 6/18 - 6/23


Wednesday morning we awoke in Reno, NV to get Sean on his flight home. Dropping him off around 8, Andrew and I were on our own. We caught a delicious breakfast at a little cafe before hitting up the Sierra Trading Post for some much needed gear. Taking care of the usual off-day tasks- laundry, food shopping, phone calls home- we headed back to the park to make camp at Manzanita Lake. The campground at Manzanita boasts the largest capacity in the park, located just past the main entrance. Offering hot showers (for a quarter a minute), fully featured bathrooms, swimming and fishing at the lake, and short easy hikes, it's no wonder this campground stays far busier than our more primitive Butte Lake location. The north end of Manzanita Lake offers a spectacular view of Mt. Lassen, pictured above.

Thursday was rather routine, taking a few repeat photos and sampling a few plots near the park road just past Chaos Jumbles. Friday began on a high note. We were working on the mid to upper slope of Table Mountain, north of Lassen and Chaos Crags, and started out with a repeat photo. We managed to find the exact location beyond any doubt, no easy feat, and always a great satisfaction. Unfortunately, the day took a drastic downturn as we headed to the first plot for the day, crossing into a shrubfield which we would be fighting our way through the rest of the day. The shrubfield was a mix of Manzanita, Ceanothus, and Chinquapin. Each of the shrubs offered much resistance to walking through, especially when going uphill. The heights of the vegetation varied from 140 to 160 cm, about chest to shoulder height. Needless to say, we were restricted to an average pace around 1 km/hr or less, and the incessant scratching, poking, and wacking of legs and arms became maddening after just a short time.

Upon reaching the first plot, we struggled to measure the slope (measuring slope requires one person to walk 20 m downhill and then back up, a feat which took about 15 minutes in the thick shrubs), and then set up the plot and were prepared to start measuring trees. Pulling out our hypsometer, I tried to measure the first tree, but the battery was exhausted. CR2 batteries are uncommon, and while we had two other sizes of CR battery, neither was correct. So, the day was made even more difficult as we then had to measure all tree heights with the clinometer. This means that rather than simply shooting the bottom and top of the tree with the digital device, I had to be exactly 15 m from the tree and estimate the difference in elevation from where I stood to the bottom of the tree. Fortunately, the plots were located relatively close together, so though we moved slowly between them, we were able to finish five plots by the end of the day. The other benefit of trudging through the shrubs were the great views of Chaos Jumbles. Pictured below, Chaos Jumbles was formed about 650 years ago when a gigantic slab of rock fell from Chaos Crags, demolishing everything in its path the whole way through the valley and up the other side a bit.

Finally arriving home around 5:30, we were happily surprised to have completed five plots and a photo while stuck in the shrubery. Andrew and I both came out of the day happy to have conquered the terrain, sustaining only minor scrapes all over our arms and bruises along our shins. While we did trump the terrain after all, it remains a location I hope never to visit again.

The next few days were quite productive, as we sampled many plots in and around Chaos Jumbles. Evan Lawley arrived Friday night with his friends Chris and Jack, and he joined us Saturday for another extremely productive day, finishing five plots in the Jumbles and doing a photo as well, despite being restricted to using the clinometer for heights again. After the second day without the hypsometer, Andrew drove to Redding and back to purchase the extremely rare yet necessary CR2 batteries.

Saturday night we were hit with a surprisingly powerful rainstorm. Beginning around 8 pm, the rain only got stronger through the night, leading to an early night for everyone in the campground. Pouring so hard I had to dig a drainage trench for my tent, the rain filled all of our pots and pans with well over an inch of water, which we were able to use to do the dishes the following morning. We got a late start because of the rain, but still managed to get 4 plots done on Sunday. Hiking around the lower part of Table Mountain, we were low enough to see some trees we had yet to see. Douglas Fir and Incense Cedar shared the area with Ponderosa Pine, White Fir, and some Sugar Pine. We stumbled upon a Douglas Fir on our way to the third plot which was so incredibly massive we had to stop and measure its diameter; the tree came out to 195.0 cm in diameter: that's 6 ft 5 in wide for all those not used to the Metric system.

For a change of pace, and a fun Friday adventure (our Friday comes on Tuesdays), we decided to do the Loomis Mountain repeat photography on Tuesday. Driving out of camp a bit before 9 in the morning, it took us until about 10:30 to find our way to the base of the mountain. We hiked up the mountain rather quickly, reaching the summit well before noon. The hike was exceptional, offering views of Mt. Shasta the whole way up. We passed by some really cool Mountain Hemlock and walked over a lot of Alpine Tundra. The only way to get closer to Mt. Lassen than Loomis is to be on Mt. Lassen. I managed to use the "panoramic assist" function of my camera along with photoshop to generate this near-360 degree view of the summit.


Needless to say, it was an incredible place. Just before leaving the very top to hike to the repeat photo locations, I accidentally kicked a small waterproof box. Retreiving it from under a rock, I opened it to find a notebook and pencil with some previous hikers signatures. Andrew and I happily read their entries and added our own. Finding the photo locations was easy, and we snapped the photos and headed back down the mountain to the van. Driving farther along the crazy, unnamed dirt forest roads, we managed to find our way to the next location to do a remote plot near the Park/Forest boundary. The plot location was incredible. We were forced to cross two streams to find it, stumbling upon a meadow with a pond in the valley of three incredible cliffs, one of which we had just been on top of, we paused to watch two Golden Eagles soar along the cliffs before continuing up the side of a ridiculously steep mountain where our plot was located. The area was breathtaking yet buggy, and while the views were incredible, the heat, humidity, and innumerable insect attacks detracted from the experience, if only trivially.

We ended the day with a fantastic concoction of noodles in a peanut-butter & hot sauce medley with crisp celery and onion pieces fried into the sauce. As a perfect finish to the day, I chose to go for a short night ride on my road bike, out to the Crags to view the stars in their pristine, unpolluted condition. The remoteness of the park, paired with a new moon, gave incredible clarity to the starts, and the milky way painted the sky like a thin viel of ambient vapors.

National bird


We had the privilege of checking out a bald eagle as it scanned Snag Lake for fish. It let us walk right up to the tree it was perched upon, and then flew off after a minute or two. Just incredible.

Photos from the past week in Lassen

A nice water-level view of Snag Lake from the north end. The camera Abram hooked me up with has an articulating LCD screen which makes it easy to take shots such as this. Thanks Abe!
A space-like view of the Painted Dunes/Fantastic Lava Flow.
The incredible and still quite snow-covered Mt. Lassen and Chaos Crags to its right as seen from the Hat Creek Rim lookout point. The lookout is about 30 minutes from our campground at Butte Lake and is the nearest location with cell phone service.
Hiking past this viewpoint several times in the past week, I couldn't resist stopping to take in the breathtaking view of Butte Lake nearly every time.
Perspective view of a nice big Ponderosa Pine. Yea yea, I tried to get a little artsy with this one.

Completing the Journey West


Stopped at a local microbrewery/restaurant in Salt Lake City on the way to Reno to catch game 2 of the Stanley Cup Final. We lost the game unfortunately, of course we ended up winning the series anyway! The beer was fantastic and I managed to find like minded individuals to converse with. A couple guys were out from Toledo Ohio for a public transportation convention. Turns out one of the guys was a cyclist and the other a geographer. It was nice to talk to someone as I was smack in the middle of a five day solo journey from Denver to Reno (with a fun stop in Fruita for some riding).
Stopped at a lookout on my way out of Fruita, just after crossing into Utah I believe.
This was the state park I camped in the night before I had to be in Reno. Rye Patch State Park is along the Humboldt River about an hour and a half east of Reno. I found a pleasant campsite in a nice area of beautifully green grass, rare for the desert; as it turns out the reason the grass was so nice is because they have a sprinkler system which runs each night. Not only did the sprinklers run all night soaking my tent, but I woke up around midnight completely befuddled as to what the heck that sound was.

Volcanic Legacy


The Cinder Cone in LVNP, photo above, exemplifies this type of volcano better than any other in the country. The cone erupted most recently in the 1600's creating the Fantastic Lava Flows and Painted Dunes. The lava flows created a natural dam which made Snag Lake, so named for the snags (dead trees) still sticking out of the lake when people first set eyes upon it following its creation. The Painted Dunes, photo below, formed when volcanic ash fell onto still hot lava and was oxidized. They are both beautiful and massive in scale, surrounding the Cinder Cone before giving way to the Fantastic Lava Flows.
The photo below depicts Mt. Lassen in the center, the largest mountain in the park, and obviously the centerpiece of Lassen Park. A plug dome volcano, Lassen last erupted in 1915. To Lassen's right Prospect Peak slowly rises up, a shield volcano which we climbed on our first day here at the park. The Cinder Cone can be seen to the left side, complete with the Fantastic Lava Beds in front of it. This photo incredibly displays three of the four types of volcano.When we first surmounted Prospect Peak, the goal was to orient all the maps and become familiar with the main peaks and landmarks in the park. We were hindered, however, by a thunderstorm complete with hail, and could not risk venturing above the tree line. A few days later, after work, I climbed the Cinder Cone. Unfortunately, my camera battery died taking the photo at the bottom, so I did not manage to capture the breathtaking views from the top. I do plan on making a repeat ascent, however, as the cone offers simply incredible views of both Butte and Snag lakes, the Fantastic Flows and Painted Dunes, Mt. Lassen, Red Cinder Cone, Hat Mountain, and several other incredible features such as the effects of some past forest fires.

So far, poor weather has followed us, with only one or two days free of rain. Most days the skys also deliver hail, the incredible variation in temperature and weather due to the parks orography. Our packs are usually filled mostly with extra layers and rain gear, along with the equipment we need such as 50 m tapes, GPS units, surface fuels photo books, diameter tapes, clinometers and hypsometers. More on all that later when I have a chance to write up exactly what we are doing day to day. PENGUINS ARE THE STANLEY CUP CHAMPIONS!!!!!!

Grand Junction - Fruita

Grand Junction, an interesting town on the central western side of Colorado, clearly shows cyclings influence in the area. This statue, just one of several relating to cycling, sits square in the center of the main street in GJ. I found a local brewery in this fine town as well; it just so happened to be where I caught game 1 of the Stanley cup final. Though we ended up losing, the young bartender was also a Pens fan and bought be a beer halfway throught the game. Cheers to Grand Junction!

Fruita, what a place! The town is quirky, a tiny town with a clear influence from mountain biking. The town made itself known in the mountain bike world way back in 1995, largely due to the hard work of bike shop employees at Over the Edge Bikes. The Kokopelli trail connects Fruita to Moab via nearly 150 miles of sweet singletrack. Fruita now boasts several trail networks specifically built for mountain bikes. I was lucky enough to spend the night at the 18 road trailhead camping- free camping year round- and the next day was spent exploring the incredible trails. Riding in the desert is unlike anything I've yet experienced. The terrain is so huge, it's like moving among giants. Utilizing the unique-ness of the terrain, trails such as Zippety Do Da and Joe's Ridge follow wild, intensely exposed ridgelines. I spent a couple hours of my day climbing up 1500 feet directly above the trails for a spectacular view; from up there it feels like you're on top of the world.
View of Zippity Do Da, the most incredible trail at 18 road. This trail was so exposed I can't even describe it. Imagine riding along a footwide trail with 60 degree slopes on each side, no trees or shrubs, and incredible views all around. Resisting the urge to look off to each side was near impossible, yet one false move and you're tumbling hundreds of feet. This trail has claimed collarbones!
These lizards were so incredible! I watched them dart out from rocks, scurry alongside my bike for a fraction of a second, and dissapear into the sagebrush all day before this one gave me the chance to capture a photo. Such cool colors, and the way they run on their hind legs is just too cool!

Beer!

A number of micro-breweries make their home in the state of Colorado, several right in Boulder itself. We had the privilege of sampling beers from the Mountain Sun Ales brewery as well as Walnut brewery. Mountain Sun had an incredible selection of extremely hoppy beers- almost too hoppy even for me. Walnut had a more balanced selection of beers; that's not to say they lacked hoppyness, simply that they offered many hoppy and malty beers alongside their hop-head favorites. Overall, Colorado fosters an incredible variety of fantastic brews; I must say, however, none of the few I was lucky enough to sample could top the yet unbeaten brewmasters at The Alchemist in Waterbury, VT. Still the best beer ever to delight my palate.



Bicycle transportation in Boulder should be the envy of any progressive town or city. Not only does the infrastructure itself blow most towns away, but the number of people traveling by bike, utilizing the incredible system of bike-only pathways is also unbelievable. We went on the "Happy Thursday" ride which is a themed costumed fun ride around town. Unlike a critical mass, the ride stays on bike paths and is strictly for fun, there really is no conflict between motorists and cyclists in this town.

Starbucks

So finally I am beginning this blog. It's been nearly two weeks since I arrived in Reno, NV to begin my internship in Lassen Volcanic National Park. So many things already have happened it's hard to relate all of them in the fifteen minutes before the Penguins take on the Wings in game 7. Suffice it to say the drive out was everything from monotonous to scintillating, and so far I have learned an immense amount about Lassen Park, forest ecology, trees, fires, camping and hiking. We just finished spending a week with Dr. Alan Taylor, the professor who advises our fearless leader Andrew Pierce. Working all over the park, we will be both creating a new data layer for an ongoing fire map and completing repeat photography (more on that later). This basically entails a massive amount of hiking around the park, navigating via GPS to the plot locations whereupon we measure many variables. This data will be used to create a new map layer of canopy fuels which, when added to the surface fuels layer as well as elevation data, will be used to simulate spreading of wildfires. This data will then be used by the National Park System (NPS) when planning prescribed burns, a necessary thing when supressing natural fire in a forest which has adapted to forest fires.

The past week and a half we've been camping at the Butte Lake campground, enjoying the relatively few other campers (Lassen VNP is the least visited national park in the NPS). Some of the amazing volcanic features of the park are just a short hike from camp, such as the Cinder Cone, Fantastic Lava Beds, and the Painted Dunes. Photos will follow this post, the park is simply incredible. The only park in the NPS containing all four types of volcanoes, cinder cone, composite, plug dome, and shield, volcanic legacy is evident everywhere. Most of the park is covered in old growth, fire adapted forest, which is simply incredible to experience. Well, Game 7 starts in just a few minutes so I must pause for now, but photos will be uploaded hopefully before we head back to camp tonight.
