Stereo analysis
AnalyzedVerdict
Camera moved / alignment issue70%
The pair does not align reliably enough for a trustworthy depth reading; scan skew can also contribute.
- Depth spread
- 6px
- The range of horizontal difference between the two views. More spread generally means more depth; 0–1 px usually indicates a monoview.
- Match
- 83%
- 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
- 4px
- Vertical drift between matched details. Lower is better; 4 px or more can indicate camera movement, scan skew, or poor alignment.
An Elmer & Tenney stereoview captioned “Southern Minnesota Division, C. M. & St. P. R’y” and “Snow Blockade, March 29, 1881.” The mount credits Elmer & Tenney of Winona, Minnesota, as photographers and publishers and identifies the card as part of their Minnesota Snow View Series of 1881.
A long line of men works in a narrow trench through deep snow, receding diagonally from the foreground toward an open horizon. Several bend over shovels; others stand within the cut, where the banks rise above their heads. A man in a long coat stands higher on the right bank, beside a ridge of broken snow blocks.
The number 1159 appears near the foot of the right-hand image and matches the reverse listing, “Snow gang at work,” designated an instantaneous view. The printed caption establishes the railway division and date, but neither the exact site along the line nor the men are identified. Winona is the photographer-publisher’s address, not an established location for the scene.
Two round-topped photographic images are mounted side by side on a pale green card with rounded corners. The reverse carries a printed list of snow views grouped under three railway divisions, together with unidentified pencil notations.

Card names no place. Same Elmer & Tenney Minnesota snow blockade series as No. 1158 (Temperance Lake cut) and No. 1161 (cut three miles west of Fairmont), both on the Southern Minnesota Division. Placed on that stretch of track by the series, not by this card.
