I spotted this snake moving through some vegetation while I was walking a trail at the Sequoyah National Wildlife Refuge in Oklahoma. I think this is a North American Racer. Snakes will rise like this so they can get a better look at danger.

I was walking the Horton Slough Trail, and I was hand-holding my camera when I photographed this snake.
