Made of two different types of sandstone, the boulder was formed when the Dewey Bridge mudstone on the bottom eroded beneath the slick rock Entrada Sandstone on top. Erosion transports the fragments away. Anglerfish, for instance, use a bioluminescent growth on the top of their heads (called an esca) to lure prey.
