The Gopher Snake

The Great Basin rattlesnake, Crotalus oreganus lutosus, is native to western Utah and can be found in a number of different habitats. This species is live-bearing and can give birth to broods of up to 13 babies. All bites from this species should be considered to be medically significant, but many bites turn out to be dry bites. A dry bite is a defensive bite where venon is not injected. Along the Wasatch Front we tend to encounter this species in late spring and early summer when they are out on the trails absorbing heat from the sun. As it gets warmer we tend to see them less and less, most commonly seeing them while hiking at night after the sun has set.

  • Length: 26" to 48"
