Stereo analysis
AnalyzedVerdict
Camera moved / alignment issue85%
The pair does not align reliably enough for a trustworthy depth reading; scan skew can also contribute.
- Depth spread
- 7px
- The range of horizontal difference between the two views. More spread generally means more depth; 0–1 px usually indicates a monoview.
- Match
- 98%
- 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
- 7px
- Vertical drift between matched details. Lower is better; 4 px or more can indicate camera movement, scan skew, or poor alignment.
A steam locomotive with a broad flared stack and large headlamp stands upright on a timber trestle, with overturned rolling stock below and beyond it. Men stand along the elevated track and gather beside the wreckage. Snow covers the foreground and the sparsely wooded hillside behind; the trestle’s cross-braced timbers are clearly recorded in both views.
The mount bears the photographer’s imprint, “Photographed by Hoard & Tenney, Winona, Minn.,” together with “Minnesota Scenery.” and the series heading “Views on the Winona & St. Peter R. R.” These inscriptions establish the attribution and railroad identification, but do not name the precise location, date, or circumstances of the wreck. The people remain unidentified.
The small number on the locomotive’s circular front plate appears to read “16,” although the numerals are not fully resolved in the scans. The reverse has handwritten annotations but no printed catalogue or numbered caption against which to check that reading. None of the reverse markings securely identifies the event.
Two arched-top photographs are mounted side by side on a green card. A small patch of surface loss with adjacent brown discoloration is visible near the left edge of the reverse; the photographs are otherwise generally clean and the card appears sound.
