I tend to pick objectives that I feel are safe because I know that, in the moment, I always go for it. I have some rules for myself, though: Look for the rock faces without a lot of loose rock.

Crevasse indicates peril in mountaineering contexts; it’s a risk faced by climbers.

Glacial Danger

Most common in technical contexts related to geology and exploration, not everyday conversation.

Technical Use

A crevasse is a large crack; smaller ground cracks are usually not referred to as crevasses.

 so we could tie off ropes and repel down into the hole. This is me looking into the entrance crevasse. At the end of this hole, we found a huge tunnel going right up the mountain underneath thousands of tons of glacier ice. We followed this cave back for about a half mile until it came to an end. And then with the help of our survey tools,

 The question is, what happens next? Does the water stay there forever? It could. Or does it find a way out to reach the global ocean? One possible way for the water to reach the bedrock and from there the ocean is a crevasse, or a crack in the ice. When cracks fill with water,
