Geology Note: Being a geologic site, it seems reasonable to describe a bit of the geology that makes up the area. The sandstone layer is Entrada Sandstone. The Entrada layer sits on a shale and siltstone layer of rock that provides the flat base of the area. Fractures in the original Entrada layer allowed for the weather process to begin. The corners and edges of the fractures weather more quickly because of their increased volume, creating the unique hoodoo shapes.

Most interesting to me, the white layer you see interspersed is actually Entrada sandstone that has had the hematite remove from it via chemical reaction from groundwater. This effectively bleaches the layer the ground water interacted with. I would have assumed it was a separate type of sandstone!
