The bottom of Shelburne Bay has smoothed up significantly over the weekend as well. It is not smooth black ice, but large plates of snow ice with numerous bumps and refrozen cracks. That being said, it does look navigable on skates. A wingsailor on skis was out over the weekend and appeared to have a great time. This morning three trucks drove out on the Southern end of the bay from the fishing access, the first vehicles I've seen on Shelburne Bay this year (in several years, in fact) although I do NOT recommend driving a vehicle on Shelburne Bay.
The Bay is frozen all the way out to Shelburne Point and Redrocks, I could not see any open water from the South end in the Bay. I have not scouted it yet, I'm hoping to skate it this evening after work. Note that the lower 1/3 locked up about 2 weeks earlier than the upper 2/3, so the conditions in the Northern portion may be very different than the Southern third.
Based on the photos of the ice near Burlington and Button Bay, I would not recommend travelling far for this ice, the overall surface quality in those photos appears far better. But if you are in Shelburne and want a quick fix, it looks like it can now be had on Shelburne Bay.
