Eastern Garter Snake (juvenile)

"Found in nearly all habitats from open talus slides, cultivated fields, open canopy deciduous and coniferous forest, swamps, marshes, and bogs to dry upland hillsides and/or human habitats. They are most often found around quarries, trash dumps, banks of ditches, canals, streams, rivers, ponds, or vacant lots, and may be found under logs, rocks, boards and other debris." -- http://www.paherps.com/herps/snakes/garter_snake
