Well, I sincerely doubt that any spot in North America in the Rancholabrean was
"predator free". I don't see the Front Range as
allowing for Megalonyx to hike up there, but not big cats, dogs, and bears.
The Snowmass site is probably simply showing something closer to the actual
predator-prey ratios (buttloads of herbivores, rare
predators), as opposed to the predator trap of La Brea.
