Such a cute Toadstool family.

The term “toadstool” is used to describe a geologic formation that is like a hoodoo but has a hardened cap rock at the top that is usually wider than the hoodoo portion (neck or base) of the toadstool. The cap rock looks like a hoodoo with a hat on top. It’s likened to a “sitting stool for a toad”, which is how it got its name.
This cap rock is typically a color (often a dark color) that is much different than the hoodoo portion (often a lighter color). Toadstools are typically formed by a less-erosion-proof earthen layer below (the base) that is protected by a small, hardened rock layer above, known as a “cap rock”.
