This is a stereoscopic photograph from the Expedition of 1872, led by 1st Lieut. Geo. M. Wheeler of the Corps of Engineers. The image showcases a rocky landscape, focusing on a large, weathered rock in the foreground. The rock is textured with horizontal lines and has a hat and a stick placed on top of it. Other rocks of varying sizes surround the main rock, contributing to the rugged, natural scene. In the background, there appears to be a sandy or gravelly area and what seems to be a rock formation or cliff face. The image uses the typical stereoscopic technique to create a 3D effect when viewed through a stereoscope.

Here is a description of the image:

This is a sepia-toned stereoscopic card, likely from the late 19th century, titled "Expedition of 1872." The card is mounted on a yellow cardstock. The two images on the card are nearly identical, designed to create a 3D effect when viewed through a stereoscope.

The scene depicts a rocky landscape. In the foreground, there are large, rounded boulders of varying sizes. The main subject of the image is a very large, roughly cube-shaped boulder that dominates the scene. This boulder has a weathered, textured surface. On top of the boulder, there is a hat and what appears to be a walking stick. The hat appears to be a wide-brimmed hat of the type worn during the late 19th century.

In the background, there's a sandy or gravelly slope leading up to a rocky cliff face. The overall impression is that this is a dry, arid landscape.

Along the right edge of the card, there is printed text that reads "1ST LIEUT. GEO. M. WHEELER. Corps of Engineers, Commanding." On the left side, it states "EXPEDITION OF 1872." There are also small numbers, "108," visible on some of the smaller rocks in the foreground. These details suggest this image is part of a documented expedition and potentially taken for scientific or surveying purposes.
