Definition
Mount Bonney is a mountain peak situated in the Selkirk Mountains of southeastern British Columbia, Canada.
Overview
The summit lies within the boundaries of Glacier National Park, approximately 30 km east of the town of Revelstoke and near the historic Rogers Pass transportation corridor. The mountain is a notable landmark for climbers and hikers due to its high‑relief terrain and the presence of a substantial glacier on its northern slopes.
Etymology/Origin
The name “Mount Bonney” was assigned in the late 19th century by Canadian surveyors. It is generally understood to honor a figure bearing the surname Bonney, likely a geologist or explorer associated with early exploration of the Selkirk region. Accurate information about the specific individual commemorated is not confirmed.
Characteristics
- Elevation: Approximately 3,100 m (10,170 ft) above sea level. Precise measurements vary between sources, but the summit is classified as a “three‑thousander” within the Canadian Rockies and Selkirk system.
- Geology: The mountain consists primarily of metamorphic and intrusive igneous rocks typical of the Selkirk range, including gneiss and diorite.
- Glaciation: The north‑facing slope hosts the Bonney Glacier, a remnant of the larger icefields that covered the area during the Pleistocene. The glacier contributes to melt‑water streams that feed the Illecillewaet River basin.
- Climbing History: The first recorded ascent is attributed to a mountaineering party in the early 20th century (1907 ± a few years). Modern routes range from non‑technical hiking approaches to technical rock and ice climbs on the summit ridge.
- Ecology: The alpine zone supports sub‑alpine fir, Engelmann spruce, and a variety of alpine wildflowers. Wildlife includes mountain goats, hoary marmots, and occasional sightings of the pikas that inhabit the rocky outcrops.
