Mud Pit Hiking
This is the kind of trail that is often called a "corduroy road" because all the logs laid across the trail resemble an extremely large example of corduroy fabric. While it's muddy (the logs rot at different rates), it's better than no logs.
A lava flow in 1959 ejected pumice cinders that covered a large region down range from the Volcano. This trail is built on top of the pumice and shows how life is reclaiming the area.
