this is in the glacier national park forum...I'm not sure if you mean the ice box canyon in YNP on the way to Cooke City...if you mean the latter, I drove by on Friday, March 10, and the ice looked fat by the creek in the ice box canyon in YNP
Omar,
There is also a Ice box canyon just off hwy 2 a few miles to the east of West Glacier. By parking at a pullout and walking the train tracks back east to the canyon you can find several varations to climb. Nothing long but approach is possible all year.
