Black Mountain (Washington)
mountain in Snohomish County, Washington, United States

Black Mountain is a 7,262-foot-elevation (2,213-meter) summit located in the North Cascades, in Snohomish County of Washington state. The mountain is situated in the Glacier Peak Wilderness on land managed by Mount Baker-Snoqualmie National Forest. Neighbors include line parent Kololo Peaks, 6 mi (9.7 km) to the east, Painted Mountain two miles west, and Glacier Peak is 5 mi (8.0 km) to the northeast. Precipitation runoff from the peak drains west into tributaries of the North Fork Sauk River, and east into the White Chuck River. Topographic relief is significant as the summit rises 3,460 feet (1,050 meters) above the White Chuck in two miles. The first ascent of the summit was likely made in 1897 by a survey team including A. H. Dubor, Thomas G. Gerdine, and Sam Strom, who named the mountain for the dark color of its rock. The ascent from the north via Lake Byrne is non-technical.
Climate
Black Mountain is located in the marine west coast climate zone of western North America. Most weather fronts originate in the Pacific Ocean, and travel northeast toward the Cascade Mountains. As fronts approach the North Cascades, they are forced upward by the peaks of the Cascade Range, causing them to drop their moisture in the form of rain or snowfall onto the Cascades (Orographic lift).

Why this record matters
“Black Mountain (Washington)” is worth following because a concise public description often conceals a longer documentary argument. Here, Black, Mountain and Washington provides the most credible route into that argument.
Maps, plans, fabric surveys and administrative records can establish how the site’s name, extent and function changed over time. The source revision retrieved here is dated Aug 10, 2026. The linked authority identifier is Q49013863. Authority coordinates are 48.083, -121.207. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1897.
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.
