I plan to go to Ogish in mid-May.  I've been looking at the area on Google Maps, you can see where the forest fire was, and the hottest burned areas show lots of white boulder tops.  
I also thought it was interesting to look at Cache Bay, that particular frame looks like it was taken just before spring ice-out.  You can see that a northwest wind has pushed the ice floe away from the shore to the southeast and the areas that opened earlier where the water current runs.
