In August 2016, Kiff Alcocer and Derek Cheng climbed the Emperor Ridge on Mount Robson, the highest peak in the Canadian Rockies.

The ridge rises 3,000 metres from the valley, and includes a deep river crossing, steep bush loose 5.7, snow and ice.

Cheng wrote about their ascent in the April/May 2017 issue of Gripped magazine. “The rock-steps above the Black Towers steepened, demanding 5.6 chimney and face moves on rock that often buckled under too much weight.

“I had one handhold dissolve in my fingers, but managed to keep my footing on the low-angled face.

“Higher up, snow and ice became more pervasive and we soon had our crampons on and were ice-tooling up wind-swept ridges and narrow, white channels between rock ribs.”
