Very wide, deep crown on Sixty Six Hundred Ridge in the upper Icicle. East facing, at... 6,600ft!

I found that the amount of new snow at road elevation increases substantially as one travels towards the crest, from 5cm at Bridge Crk to over 45cm at the Rock Island Bridge.

Pt 6842 off a SW ridge of Grindstone Mtn, S/SW facing, crown on the right, filled in.
