2: This is a photo of Mt. Pitt in Oregon. I love the blending of all the vibrant colors. If I could change this I would change the position of the mountain.

3: This was taken from the rim of Crater Lake. I love all the different elements in this photo coming together as one beautiful picture. If I could change this photo I would make it less grainy which is due to high ISO | "Wizard Island Magic" Alexandra Sines Digital Photography June 17,2012

4: This picture was taken at twilight. I love the vibrant greens in this photo and the ominous look of it. If I could change one thing I might make it brighter.

5: This picture was taken at sunset outside of the girls cabin.I love the way that the foreground is completely black but the sky in the background is filled with color. However I would make the colors a little brighter if I could

6: I really like this picture. I love how this picture shows the curve of the lake and the beautiful forest and mountains. However it's not perfect. One problem with this is it's a little under exposed and could be brighter. Other than that I love it!

20: The Cascade Mountain Range stretches from northwestern California to southwestern Canada. It's located on the convergent plate boundary between the North American and Juan De Fuca plates. The mountains lie above a subduction zone, which formed as the Juan De Fuca plate ( which is the denser oceanic plate) dove under the North American plate (buoyant continental plate). Subduction formed the volcanoes within the Cascades as magma from the mantle moved upward through the continental crust creating extremely explosive volcanoes like Crater Lake (formerly Mt.Mazama).

21: Mt.Mazama formed over hundreds of thousands of years in a series of volcanic eruptions that included both lava flows and ash. In its prime, the volcano was more than 12,000 feet high and had the title of the largest volcano in the Cascades. Before its eruption Mt.Mazama was classified as a composite or stratovolcano. These volcanoes are the biggest and most explosive type of volcanoes that exist. Instead of lava these volcanoes are characterized by violent felsic eruptions of volcanic ash and pyroclastic flows. | About 7,700 years ago Mt.Mazama erupted in one of the largest volcanic eruptions in North America in the past 10,000 years. The eruption started with a huge blast that sent a column of ash into the air a mile wide. The ash was followed by a series of pyroclastic flows which erupted from vents on all sides of Mt.Mazama blanketing southern Oregon. This was followed by a series of eruptions that were so rapid Mt.Mazama's magma chamber completely emptied out and the mountain collapsed in on itself. This collapse created a caldera five by six miles in diameter and about 1 mile from its’ highest point to the bottom of the lake, which is now known as Crater Lake.

22: In the 2000 years after the massive eruptions that formed the caldera, several small volcanic eruptions formed Wizard Island, Merriam Cone and the Central Platform within the caldera. Eventually rain and snow filled the caldera and formed the lake. Crater Lake remains an active volcano today, which means there are still some present-day hazards. One hazard is a hydromagmatic eruption which is caused by the violent mixing of lake water with erupting magma. However, the depth of the lake could prevent this. The most serious hazard is the possibility of another pyroclastic surge destroying the surrounding area.However there are still typical dangers such as the earthquakes and landslides that can precede a volcanic eruption.

23: One technique we used in tracking that I found very helpful was recognizing concentric rings in different substrates. This really helps because after a while tracks will erode but the rings they make last. It also helps us become more aware that everything we do affects the environment around us. Consider a foot print. When you step on the ground you make a depression, but the track goes far beyond just that footprint. The grass around the print starts to shift and rearrange, in turn making the area beyond the grass shift too. That is what I mean by concentric rings. Everything is interconnected. | Tracking Journal

24: Ohio Tracking | Observer: ALexandra Sines Date: June 25,2012 Location: New Albany Duck Aviary Habitat: old field next to duck pond Description: Killdeer nest, 4 eggs that are white with black specks. The nest is made of twigs, dry plant material and dirt.It's about 3 in. long. Notes:Killdeer was sitting on the nest when we came across it | Observer: Alexandra Sines Date: June 25,2012 Location: New Albany Duck Aviary Habitat: Dried creek bed next to Duck pond Description: suspected raccoon tracks. 2.5 inch wide tracks in a dry creek bed. Notes: tracks were made when the mud was wet and were preserved when the mud dried.

25: Observer:Alexandra Sines Date: June 25,2012 Location:Duck Aviary Habitat: old field next to duck pond Description: Female Killdeer sitting on her nest. She's also alarmed by us and puffing her feathers. Notes: She and her Mate were fighting us when we photographed her nest | Observer:Alexandra Sines Date:June 13,2012 Location: Vernal pools off of Fodor Rd. Habitat: forest Description:turkey track found next to a vernal pool in Swickard woods. | Observer:Alexandra Sines Date: June 13,2010 Location: Vernal pools and forest off of Fodor Rd. Habitat: forest Description: the track of a deer that slid into the mud.Was fairly recent, and slid more than an inch in the mud. Note: This track was made when the ground was wet so it had to be at least 12 hours old because it rained the day before.

26: Observer:Alexandra Sines Date: June 21,2012 Location: Cascade-Siskiyou landbridge Habitat: forest in the cascade mountains Description: bear track on the gravel road to the landbridge Note: tack has been made lighter for greater visibility. | Oregon Tracks | Observer: Alexandra Sines Date:June 19,2012 Location: Soda Mountain wilderness Habitat: grassy valleys and mountain forests. Description: scat found next to a trail, at least a week old and mostly hair. Notes: definitely came from a carnivore because it had little bones in the middle. The animal was probably medium sized, maybe a coyote?

27: Observer: Alexandra Sines Date:June 19,2012 Location: Soda Mountain wilderness Habitat; forests Description: tiny squirrel tracks found on the walking path in Soda Mountain wilderness. Notes: they looked like tiny handprints and were smaller than my lens cap. | Observer: Alexandra Sines Date:June 19,2012 Location: Soda Mountain wilderness Habitat: grassland and forests. Description: | Observer:Alexandra Sines Date: June21,2012 Location:Cascade-Siskiyou landbridge Habitat: forests and grasslands in the cascade mountains Description: My sketch of a deer track I found in a meadow Notes the track looked fairly new and was well defined in the dry rocky soil of the meadow I found it in.

28: Scientist in the field | One of the instructors in Oregon was Irene Brady. She specializes in scientific illustration. She travels around the globe and illustrates her trips in her published journals. Her drawings are so accurate that I was amazed when I first saw them. She taught me a lot about drawing with my right brain. | Drawing with your right brain is about drawing what you see instead of drawing from memory. In our first lesson, Irene taught me to draw the out line first instead of rushing the outline and working on the details. At first it was hard because everything just looked like a blob but the more I repeated the exorcise the better I got. I'd have to say the hardest part for me was drawing with perspective without an eraser since we had to use ballpoint pens.

29: My name is Alexandra Sines. I am a freshman at New Albany High School, and I love tracking and photography. I've always been interested in geology. When I was little I wanted to be a volcanologist and I studied volcanoes as much as I could. Before this trip I was interested in tracking, so when I heard about this course I knew it was for me. I have learned so much from this experience. I have learned about the composition of igneous rocks and how to identify and document tracks. I think this experiences will help me in the future. For instance It has given me an advantage in science and photography. Perhaps this experience will help me in my future career. I know I'll always treasure it and remember it for the rest of my life. | Biography
