Precipitation runoff from the peak drains to Big Sheep Creek which is a tributary of the Columbia River.
Topographic relief is significant as the summit rises over 1,600 metres (5,250 ft) above the creek in five kilometres (3.1 mi).
An ascent of the summit involves hiking 9.4 kilometres (5.8 miles) and 974 metres (3,195 feet) of elevation gain, with the months of July through October offering the best time for visiting the popular destination.
The mountain's toponym, presumably a reference to the USA flag, was officially adopted on June 2, 1950, by the Geographical Names Board of Canada.
The peak receives precipitation all year, as snow in winter and as thunderstorms in summer.
