A black and white landscape photo of a highly eroded sandstone feature. The tall shear hills with conical shaped eroded debris at their base sit in a undulating sagebrush plain. The feature angles across the frame from center-right and disappearing off the center-left. On the far right is a vertical twin spire like a two prong fork. The prong furthest right is narrow and short while the prong on the left is wider and taller. Behind the feature on the right is a second blocky sandstone mass that looks like a large building or apartment complex with a lot of eroded material surrounding its base. A beam of sunlight strikes the feature on the far right and angles down lighting the base of the large block on the left. Otherwise the scene is dark and the sky is filled with dark clouds.

A wall of rock exposed in the Black Canyon of the Gunnison in western Colorado. The wall consists of dark grey-ish, Precambrian-age gneiss and schist dissected by bands of pink, granitic, also-Precambrian-age pegmatites (igneous intrusions that were injected into fractures in the gneiss long after it formed and while it was all still buried deep underground). The metamorphic rocks formed around 1.8 billion years ago, but existed as sedimentary rocks of undetermined age before being metamorphosed. The pegmatites, which include crystals upward of 2 m (6 ft.) in length, are a bit younger at around 1.35 billion years old. The green plant life at the top of the wall grows on mudstone exposures of the Upper Jurassic (~150 million year old) Morrison Formation, which has produced a few dinosaur fossils in the park.
