We went out on Portage Lake in a ice-breaker boat. When it plows through the ice it creates these cool little needle-shards along the fault lines.
Portage Glacier: The nearby weather station mid-April recorded winds of 214 mph.
Our guide was telling us that those crevasses go a very long way down. A couple of weeks ago, a bear was trying to cross the glacier, fell into a crevasse, and is presumed dead. Occasionally a bear does make it across; they've also been seen swimming across the lake.
