Mass wasting, also known as slope movement, is
the geomorphic process by which soil, regolith and rock
move downslope under the force of gravity. Types of mass
wasting include creep, slides, flows, topples, and
falls, each with their own characteristic features, and
take place over timescales from seconds to years. Mass
wasting occurs on both terrestrial and submarine slopes,
and has been observed on Earth, Mars, and Venus.
This was a small mass wasting episode in the
Mojave Desert of southern Nevada. Continual toppling
of sandstone will eventually result in these rock
formations transforming themselves back into sand.
