More blue than appears in photos. Found in small slow-moving shore area in the Truckee River, released under rock in that same general area.
Recently decapitated gopher snake; an interrupted lunch for a nearby red tailed hawk
Difficult to get pictures, seen frequently at this lake
Note: I did report this to the USDA who immediately and safely removed it.
I'm assuming it was an escaped pet, given how cold our winters get. It was approximately 3ft long to the tip of its tail, if I'm remembering correctly.
