Etymology

Origin of badlands

An Americanism dating back to 1850–55; bad ¹ + land + -s ³; translation of French mauvaises terres, alluding to the difficulty in traversing such country

Explanation

Badlands are a type of dry land where very few plants grow. Badlands can be found in South Dakota and Montana, among other places. The terrain known as badlands are often starkly beautiful, barren of vegetation but marked by layers of clay soil and patterned by the erosion of the wind. There are badlands in several different countries, including Canada, Mexico, and New Zealand, but some of the best known are in Badlands National Park in South Dakota. The word badlands is a direct translation of the French term mauvaises terres.
