As you drive north along Highway 155 there are several spectacular frozen falls that are situated within deeply cut cirques; Zenith being one of them.
Watch for the cirque containing the obvious route between mile marker 14 and 15 along Highway 155.
The first pitch is very long, so bring a sixty meter rope. It is hard to setup a belay before the mid-point tier, so be prepared for some potential simul-climbing. The second pitch is much shorter and can be climbed on the left or the right, with the latter being the more challenging option.
