Badlands are a type of dry terrain where softer sedimentary rocks and
clay-rich
soils have been extensively
eroded by wind and water. They are characterized by steep slopes, minimal vegetation, lack of a substantial
regolith, and high drainage density. They can resemble
malpaís, a terrain of volcanic rock.
Canyons,
ravines,
gullies,
buttes,
mesas,
hoodoos and other such
geological forms are common in badlands. They are often difficult to navigate by foot. Badlands often have a spectacular color display that alternates from dark black/blue coal stria to bright clays to red
scoria.
