The Rockies are a group of outcroppings, all connected to an obtuse piece of sloping hill side. The drop from one of the Rockies to the bottom is an extremely dangerous...eight feet at most.
This is a place that a lot of the cubs enjoy playing in. The name, in fact, came from a group of said cubs. However childish it is, it caught on and soon the whole pack was calling it "the Rockies".
The Rockies not only are a prime playground for cubs, but they are home to a herd of mountain goats as well, which makes for more or less easy pickings.
