Booming Ice Chasm - Crowsnest Pass

June 26th, 2016. Not knowing what type of restrictions will be in place once the Castle Wilderness becomes a provincial park, we decided to check out the Booming Ice Chasm now. This is truly an amazing wonder deep inside a mountain.

We required 4 full (60-70m) rope lengths to get to the bottom of the main chamber. Other than a couple sets of bolts at the top, all the other bolt locations were still buried under the ice. So we had to make ice anchors the rest of the way. The ice was perfectly polished with an angle of 50 degrees at the top, and then mellowing out to around 35 degrees further down. So either ice climbing, or glacier mountaineering experience is a must. This is not a place for beginners.
