Back in the day we used to go hunt rattlers (pacific rattlers, a lot more docile than diamondbacks or timber rattlers). We found a couple dens like this, though they were down in the ground more (hibernating I reckon). Very lethargic in those holes, but the ones we found out at other times were more lively. Wear thick vibram soled boots, stick your foot out at them, let them strike the bottom, then stomp down good and quick. Their fangs get hung up in the tread and a little stomp and maybe a twist and the fangs come off, better still the snake's neck also gets broke quick. Pacific rattlers aren't good eating for some reason, must be different sort of forage that puts their meat off. Make good headbands though. We gave that up long ago, but for a while it was interesing. I'll take snakes over spiders any day.
I dunno as I'd be sticking my foot out at that pile, though. I prefer them one at a time. If I had to eat, I'd be looking for a big willow switch or saguaro spine or some such, depending on where I might be. Better still would be to use my mates' methods from Queensland; run a chain down a 6' length of hose. They used that to ward of the Tai-Pans and Browns, at least that's what they told me. Pit vipers aren't real aggessive, not like them nasties down under.
If it weren't a matter of survival, I'd just get some pics and move on, watching my step.
Kinda reminds me of the round-up Cousin Eddie would use to keep his kids occupied out in the Vegas desert.
