3. Igneous Rhyolite I believe this rock to be Rhyolite. Part of the Igneous family of rocks. Its texture is aphanitic or “fine grained” and it is a rosy/gray color. 8 Rhyolite is not as common as other forms of Igneous rock but occurs in areas where volcanoes are present. I am probably wrong but this is my best guess.

4. Igneous Andesite This rock looks to be andesite. It is “medium-gray, fine-grained” and also contains what look like black crystals. 9 Andesite is also commonly found around volcanoes located around the Pacific Ocean so again it makes sense that I would find this near Mt. Shasta.

5. Igneous Norite I had a hard time attempting to name this rock. It looks like a lot of different rocks and the texture is hardly telling. I think it looks most like Norite. Norite is a intrusive igneous rock meaning it is coarse grained and contains minerals which are visible on this rock in the light.

7. Sedimentary Conglomerate This is a really good clear example of conglomerate detrital sedimentary rock because it very obviously contains many other smaller rock particles. I think I found this and a few others like it at Mount Shasta because of the glacial activity there along with the occurrence of avalanches on the constantly snow capped mountain.

9. Metamorphic Schist To me this rock resembles schist. Schist is a type of metamorphic rock that is formed over time by “heat, pressure, or stress” and all of those things were surely happening up until the last 200 years on Mt. Shasta. 14
