Tiger Mountain here in Washington State is literally my backyard. Our house sits on its foothills and I see it nearly every day on my walks, in different light -- clear summer morning light, foggy early spring light. The clear man-made cut into its side to make room for power lines looks so artificial next to the more organic shapes around it, and the power lines have often looked like Japanese torii gates to me. I did a series of small studies of this mountain and have since made occasional bigger pieces about it.
