Blackhorn Peak is located within Jasper National Park in the Canadian Rockies.

The nearest higher neighbor is Throne Mountain, 1.57 km (0.98 mi) to the northeast.

[4] Precipitation runoff from Blackhorn drains north into the Astoria River via Campus and Verdant creeks.

Topographic relief is significant as the summit rises 1,290 m (4,230 ft) above the river in 2.5 km (1.6 mi).

[8][9] The mountain's toponym was officially adopted in 1935 by the Geographical Names Board of Canada.
