Stereo analysis
AnalyzedVerdict
Monoview (identical duplicate)74%
A monoview: the same photograph printed twice, so no genuine stereoscopic depth is present.
- Depth spread
- 1px
- The range of horizontal difference between the two views. More spread generally means more depth; 0–1 px usually indicates a monoview.
- Match
- 100%
- 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
- 2px
- Vertical drift between matched details. Lower is better; 4 px or more can indicate camera movement, scan skew, or poor alignment.
Large slabs of broken ice fill the foreground of this stereoview. Two men in brimmed hats stand on the ice near the centre, while a third sits on a wooden rail at the right. Behind them lies a low paddle steamer, its two funnels and raised wheelhouse outlined against the sky. A wooded bank stretches across the distance.
The card has no readable printed caption or maker’s imprint. Its plain reverse bears a large, faint pencil mark, but no legible wording that identifies the scene. The river, steamer, and men remain unidentified, and the scans do not establish a photographer or date. The boat’s position among the ice is visible; whether it was trapped or damaged cannot be determined.
The two brown-toned photographs are mounted side by side on a rounded-corner buff card, measuring 7.02 × 3.53 inches. A small area of surface-paper loss and a dark scuff are visible on the reverse; the photographs are otherwise clean and the card sound.

Location
Yukon River ice break-up at Circle City, Alaska — May 21, 1897 · Circle City, Alaska, United States
Photographed subject · Street / district · 85% confidence
Provisional reading of the inscription along the lower photograph margin: “[…] Circle City May 21 '97 Alaska”. Opening unreadable; “Ice jam” is not confirmed and exact punctuation remains uncertain. Owner-adjusted clip supports this tentative place/date reading, not an exact transcription. Existing reported Sather comparison remains a separate identification lead, not proof of a visible signature.
