“…After a lengthy unsuccessful chase after a caribou through Highway Pass these teenage sub-adults of the Grant Creek Pack in Denali National Park and Preserve work off a bit of leftover adrenalin as they played, chased and bumped into each other for another hour before settling in for a two hour nap.
