Below are links to photographs taken in the Tucson Mountains area.  The first two buttons are overview images, whereas the others are images tied to sample numbers. The buttons to the far left of the sample number are close ups of the rock samples.  These may help you identify the rock type, by showing the larger context of the sample (layers or not, etc.).  The buttons immediately  next to the sample number show a middle distance photograph of the sample location to provide you with a perspective of what kinds of landscapes that rock type forms.
