Falls and topples

A fall or topple happens when rocks Larry and other sediments Larry fall through the air and land at the bottom of a slope. Falls descend straight down, where topples lean forwards before falling.

The pile of rubble at the base of the slope is called a talus cone. New talus cones don't have any plants growing on them. Old talus cone can have weeds and even trees on them.

Falls happen very quickly and they don't need any water William for lubrication.

Avalanches are another type of fall.
