Stereo analysis
AnalyzedVerdict
Genuine stereo pair96%
The two photographs contain the viewpoint difference needed to produce genuine depth.
- Depth spread
- 4px
- The range of horizontal difference between the two views. More spread generally means more depth; 0–1 px usually indicates a monoview.
- Match
- 97%
- The share of usable picture detail that can be matched between the left and right views. A higher number means a more reliable comparison.
- Vertical
- 1px
- Vertical drift between matched details. Lower is better; 4 px or more can indicate camera movement, scan skew, or poor alignment.
A tall, tapering rock pillar rises above a broad, eroded base, its narrow neck supporting a dark, overhanging cap. Small trees and broken branches cross the foreground. At the lower right, a man in a brimmed hat and jacket looks upward, providing a measure of the formation’s scale.
The front caption reads “Natural Rocks, Monument Park, Col.” The reverse label supplies the more specific title “The Utes’ Medicinal Monument,” numbered 25. Its accompanying text describes the erosion of the rocks and names suggested by their resemblance to other forms; it does not explain the title’s reference to the Utes. The historical title is retained here as the publisher’s wording.
The reverse bears the imprint “Gurnsey’s Rocky Mountain Views,” with publication at Colorado Springs, Colorado, and the series statement “Scenes on the line of the Denver & Rio Grande Rw’y.” This establishes the card’s railway-related publishing context, although no railway appears in the photograph. The card is undated, the man remains unidentified, and no separate photographer credit is given.
The two arched-top images are mounted side by side on a yellow card with rounded corners. Both printed labels remain legible. The mount shows edge and corner wear, while conspicuous irregular pale surface marks affect the upper portion of the right-hand image.
