If you can't travel to Yosemite the next best thing is to have friends who did. Many thanks to Kurt for the photo reference for this ACEO. This is Tenaya Lake at Yosemite National Park.
From Wikipedia: "Tenaya Lake is named after Chief Tenaya, who met the Mariposa Battalion near the shores of the lake. Ironically, Tenaya protested that the lake already had a name: Pie-we-ack, or "Lake of the Shining Rocks." This original name is now attached to a granite dome to the east of the lake."
I think I need to paint a much larger version of this scene!
