This picture wasn't taken from the Lassen Peak's summit
but from the trail to the summit. It shows the park road (and the parking
lot at the head of the trail) and one of the many lakes of Lassen National
Park. Once you reach the summit you can hike around it and see the remains
of the last eruption of Lassen Peak, which took place in 1914. Much of the
chunky rocks at the top were pushed out at the time of the eruption. By
hiking around the summit you can also enjoy nice views of the park and of
the mountain ranges that surround the park. But don't forget to bring a
jacket, it's very windy at the top.
