Stereo analysis
AnalyzedVerdict
Genuine stereo pair88%
The two photographs contain the viewpoint difference needed to produce genuine depth.
- Depth spread
- 3px
- The range of horizontal difference between the two views. More spread generally means more depth; 0–1 px usually indicates a monoview.
- Match
- 91%
- 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
- 3px
- Vertical drift between matched details. Lower is better; 4 px or more can indicate camera movement, scan skew, or poor alignment.
A steam locomotive faces the camera in a narrow opening through deep snow. Men stand on and beside the engine, while another holds a shovel high on the snowbank. A rope runs across a row of cut snow blocks in the foreground, beside a man in a long dark coat.
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.” The lower caption names the Southern Minnesota Division of the Chicago, Milwaukee & St. Paul Railway and reads “Snow Blockade, March 29, 1881.”
View number 1156 appears in the right-hand photograph. The publisher’s printed list on the reverse identifies that number as “Drawing snow blocks out,” with the entry underlined in pencil. Neither the precise location along the division nor the men’s names is supplied.
The paired, round-topped photographs are mounted on cream card. A small brown stain is visible near the foot of the right-hand image, with a few localized brown spots on the reverse; the card is otherwise sound. The reverse also carries 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.
