I went to Mountain School on the March 17 through the 19. I learned that rivers make a v shaped vally and glaciers make a u shaped vally. Deoblo Dam is a u and a v shaped vally. I also got to see the last seneca white deer. Teddy Rosavelt gave a herd of white deer to the North Cascade National Park he lived in New York. I also learned how to know the type of animal it is by looking closly at the tracks they make.
