This data set is composed of mostly black and white, and some color, photographs of the volcanic cindercone 
            Amboy Crater and its surrounding lava flows, located in the Mojave Desert of southeast California. The photographs were 
            taken by Dr. Ronald Greeley and Dr. James Iversen in 1976 and acquired using hand-held cameras. The photographs were taken 
            at low altitude from a fixed-wing aircraft, on the ground near volcanic outcrops, and of flows from close up. The purpose 
            of the images was to depict volcanic features on Earth that could be studied as an analog to features similar to those 
            found on Mars and the Moon.
