Okay, there is a Spider Mountain in Washington state. I looked at a number of range / peak profile images, but the only one that really inspired me was John W Porter's Final ridge traverse on Spider Mountain, so that's what I tried to paint. I really struggled with this one, not having any browns in my watercolors. So, I cheated and used the colors already in my mixed paint wells.
At first, I didn't like this painting. The more I see it, however, the more I like it. If you view from a bit back, the ridge actually looks a bit three dimensional.
