Hazard Stevens and P. B. Van Trump completed a documented ascent of Mount Rainier in August 1870. Indigenous people knew the mountain long before these expeditions.
The Disappointment Cleaver, Emmons–Winthrop, Kautz Glacier, and Liberty Ridge routes are reconstructed here using historical OSM geometry, NPS waypoints, and clearly identified terrain-inferred connections. None is a current navigation track.
