Here's a couple of sunset shots of Lake Muskoka from our balcony at the Marriott in Gravenhurst, Ontario, on the 4th of August. This one was actually later than the next one and the cloud formation was really something. Sunset was about 9pm in this northern latitude.

In this shot you can see more of the marina and boat docks in the dusk and the tree to the right was particularly photogenic. It was about 70 degrees and a wonderful evening with wine on the veranda and what a view.
