This is an old sepia-toned stereograph image showing a pair of identical photographs side by side, meant to be viewed with a stereoscope for a 3D effect. The scene depicts a rugged outdoor environment with rocky ground. In the center of each image is a prominent cactus with dense clusters of spines, standing out amid the rocky landscape. The images are bordered with a yellow frame that includes text at the top: "EXPEDITION OF 1874." In the lower right corner, there's text indicating the expedition's leader, "1st Lieut. Geo. M. Wheeler, Corps of Engineers Commanding." The number "13" on a small piece of paper is also visible in the central part of both photographs, suggesting it could be an item number or identifier for the image within the expedition's collection. The overall historical and natural context of the images suggests they were created for scientific documentation or geographical exploration purposes.

This image shows a close-up view of several cactus plants or other spiny succulent plants. The plants have a distinctive globular or barrel-shaped form with numerous sharp spines or thorns covering their surfaces. The plants appear to be growing on or among rocky or sandy ground. The image has a sepia-toned, vintage photographic quality, suggesting this may be an older stereoscopic or 3D-like photograph.
