I received reports last night from people at cottages on the north end of Canoe Lake saying that there is open water there, and that they were able to reach the south end where there is also some open water on the west shore (the opposite shore from the Portage Store). This news, combined with the warm weather coming, and the opinion of Algonquin Park staff that corridor lakes will be ice-free by Saturday, all suggests that we are less than 72 hours from ice-out.
There is only one thing to do now -- get up there and see for myself! I'll be leaving shortly and will do my best to report in here late this afternoon or this evening. But in case I am not able to get a post up here, you can also check this Mobile Me gallery for photos posted directly from my iPhone.
