This is the ice wall on the Kootenay Plains west of Rocky. It's well used by ice climbers and tends to stay intact well into June.
There's a path beside it for those who wish to hike up the ridge.
I've done it. I recommend it.
The ice wall becomes a mud wall in summer as it is spring-fed. Despite that, it is climbable in the summer. Start on the side path and and then switch over to the drier parts of the mud wall.
It has good rest spots with spectacular views.
