Looked dangerous to me. They were far away. Shot with a 24-70 mm L series lens. Cropped to see the guys jump off the rocks into the alkaline lake. There are three views of the same frame, figures jumping get smaller and smaller. A mini-slideshow.
On the Colville Tribal Reservation, “Omak Lake, the largest saline lake in Washington, is located southeast of Omak. It lies mostly within a steep-walled valley and is the principal body of water in the Omak Lake watershed. Omak Lake has no outlet and is fed by drainage from the surrounding hills and plateaus and from several inlet streams.”
