This was the first large rattlesnake to emerge from this den in North/Central Idaho. This place has to be right at the limit of high elevation and Northern range of these snakes – when I first heard of this location, I was almost skeptical of the identification, thinking that the Northern Pacific rattlesnake would be a more likely bet. I was wrong – we watched 10 Great Basin Rattlesnakes climb out of the rocks over the course of a few hours on a rather chilly, windy day.
