mohave green rattle snake

[raven2]

Hello all , a newbie to the forum

Have a question about rattle snakes, specifically, Mohave Green Rattle Snakes as named out here in West Antelope Valley, CA.

Recently saw a Mohave Green rattle Snake in a hole made by a ground squirrel or a mole. Most probably made by the ground squirrel because it was too large for a mole hole. There was also a back door hole about four feet from the main opening.

I covered both holes with 1/4" pea gravel to isolate the snake ,because I had to finish dressing up the motes around the small almond tress and do some weed cutting.

How long can the snake survive in this environment with the gravel covering the holes?
