Eadweard Muybridge (spellings changed over time) was a famous 19th Century photographer. He was most famous for winning a bet for Leland Stanford that horses lifted all four feet off the ground when galloping. Muybridge visited Donner Summit and made a number of photographs. This one is of what he called Lake Flora (named probably for his wife). Today it's Crater Lake and another Lake Flora is a few miles east. This shows the change in forests from the days emigrants take their wagons through to today when much forest land is as thick as a thicket because of Smokey the Bear (modern fire prevention strategies).
