Flattop Peak is a {{Convert|3063|m|ft|abbr=off|adj=on}} summit in British Columbia, Canada.

Description

Flattop is located in The Bugaboos, west of the Bugaboo Glacier along the southern boundary of Bugaboo Provincial Park.{{cite bcgnis|id=12875|name=Flattop Peak|access-date=2023-02-08}} Precipitation runoff from Flattop Peak drains east into Bugaboo Creek which is a tributary of the Columbia River; as well as west to Duncan River via East Creek. Flattop Peak is more notable for its steep rise above local terrain than for its absolute elevation as topographic relief is significant with the summit rising 1,660 meters (5,446 ft) above East Creek in {{convert|3|km|mi|abbr=on}}. The nearest higher neighbor is line parent Howser Peak, {{convert|1.21|km|mi|abbr=on}} to the southeast.

L. |author3=McMahon, T. A. | year = 2007 | title = Updated world map of the Köppen−Geiger climate classification | journal = Hydrol. Earth Syst. Sci. | volume = 11 | pages = 1633–1644 | issn = 1027-5606}} Winter temperatures can drop below −20 °C with wind chill factors below −30 °C. This climate supports the Bugaboo Glacier on the peak's east slope and an unnamed glacier on the south slope.
