I looked up the Wikipedia page for Crevasse and found this photo:
The glacier Taschachferner below the Wildspitze (left, 3.768 m) in Tyrolia in Austria in April 2005. There are some zones with large open crevasses, e.g., the spot-shaped area below the middle of the image and most right. The line marks the ascent track of mountaineers on skis which intentionally avoided these dangerous areas.
Here is the source. Thanks and good cheer to my many thousands of readers, other projects have diverted me from making regular updates to this website but I appreciate you and our shared enthusiasms!
