Rocks - lots of rocks
The rock faces of the San Gabriel Mountains have a particular look. The shapes are sharp and they are made of very crumbly material. Grasses have a hard time growing between the rocks because there are so few nutrients and things to grasp with their roots to survive. When the rains come, anything that can get a grip grows fast and takes advantage of the short wet season. The canyon wren, Catherpes mexicanus, is peeking from under the large bolder.

This photo is becoming a painting. It is taking longer then I thought it would but I am finding so many wondrous things that live in this vertical quarry. Centipedes hide in the cracks waiting for a juicy beetle. Grubs, beetle larvae, emerge from their winter sleep. So, no wonder brown creepers and wrens hop about these places.
This rock face is adjacent to the face in the upper image. It is composed of completely different substances and is far more crumbly. It bulges as if it is about to pop - I did not alter the image or enhance it.
Many veins of speckled rock have very large boulders that project out over trails and roads. Considering how crumbly and loose the pieces are, these faces can be quite a hazard. But, oh, how dramatic they are.
