Interesting. Thanks for the responses, guys.
The area I'm talking about is the southern end of the Central unit, by the way. Good to know it's just a localized situation, but I wish it wasn't in my stomping grounds. :wink:
FWIW, it isn't because of predators. I heard coyotes every evening, but the carcasses weren't eaten at all.
Chalk it up to yet another good reason for micromanagement, I guess.
