Okanagan Mountain at 6 a.m.
Perhaps you can see the western wall of the valley, to the right, tip nearly vertically as it moves east and collides with the westward-moving mountain coming in from the right? The collision bent this valley (and its 135-km-long lake) nearly 90 degrees. The wind patterns on the water above are typical, as the bend creates a meeting space for two completely different wind patterns. Rather like the Moon and the Sun.
