Quick Reference

An erosional feature that is seen in badlands. It may result from severe gully erosion, but a hoodoo often develops where a resistant cap rock protects softer sedimentary strata. Rain erodes the softer rocks, leaving a pinnacle, which is the hoodoo. Hoodoos also develop where a boulder protects till. Hoodoos are often conical in shape beneath the cap rock and they sometimes occur in groups. Their curious shapes, which from a distance may bear a faint resemblance to a robed human figure, account for their name.
