Williamson Mountain
mountain in United States of America
Williamson Mountain, elevation 6,304 feet (1,921 m), is a peak in the Cascade Range in the U.S. state of Oregon. It is named after Lt. Robert S. Williamson, who with Lt. Philip Sheridan took part in the Pacific Railroad Surveys in central Oregon in 1855. The United States Board on Geographic Names approved the name in 1931. Before that, the peak was known by its Chinook Jargon name of Leloo Mountain (Wolf Mountain), derived from the French le loup (the wolf).
The mountain lies slightly east of the border between Lane County and Deschutes County in the Deschutes National Forest and the Three Sisters Wilderness, southwest of Mount Bachelor. The Six Lakes Trail crosses the mountain between Lucky Lake to the southeast and Senoj Lake to the northwest. Forest Road 46 (Lava Lake Road) is about 2 miles (3.2 km) east of the mountain.

Why this record matters
“Williamson Mountain” is worth following because a concise public description often conceals a longer documentary argument. Here, Williamson, Mountain and mountain provides the most credible route into that argument.
The strongest evidence will usually combine a dated visual record with documents produced by the authority responsible for the place. The source revision retrieved here is dated Aug 16, 2026. The linked authority identifier is Q8021227. Authority coordinates are 43.924, -121.825. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1855 and 1931.
A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
