Sierra Nevada Species: Garter Snake

I found this beautiful snake basking in barely flowing water at an elevation of about 5800' in the Sierra Nevada mountains of California. At first I thought it was a striped racer, but racers have two light stripes on their sides, while this one has a light stripe down the middle of its back and a light underbelly. It appears to be a juvenile garter snake, or at this altitude, it could be full-grown, morphologically adapted to a less plentiful food web. It's rather small, about 24" long.  Click any image below for full size.
