cuesta
A hill or ridge with a gentle slope on one side, and a steep slope on the other.
At that point the cuesta is 10 miles wide but the hilltops have an eastward descent of only about 62 feet. In its general eastward slope the surface of the cuesta is exactly that of one made by weathering and stream erosion, acting upon a gently-dipping limestone bed in a region never glaciated.
Where it comes from
Borrowed from Spanish cuesta (“slope”). Doublet of coast.
