A medium to large (up to 900 mm or 36" in total length) gray, brown, or orange-brown snake with a single cream colored stripe down the midline of the back (dorsal stripe). There are usually two additional thin light stripes on the 2nd and 3rd scale rows of the lower sides (counting up from the belly). Some specimens lack stripes or have very diminished stripes. Alternating dark blotches mark the areas between the stripes. These dark blotches often intrude into the stripes. The underside is light gray or cream, occasionally with flecks of brown or orange
The pupils are round and the dorsal scales are keeled.

This primarily diurnal snake
ibernates during the cold months of late fall and winter.
