This pressure crack now has open water, and at this point it's about 50 feet deep.

We went for a walk on the ice yesterday, probably the last one this winter. In this photo Pat and Spike are walking along the open pressure crack that is about 100 feet off shore. The open water is in an area where the water depth is 50 feet. It's a very early spring here, and it looks like the ice is starting to break up early. It is, however, 4 weeks or more from being ice free.
