Denali National Park consists of six million acres of wilderness, yet is accessible from Alaska's road system and popular with tourists. I spent three nights at Teklanika camp ground, riding the park buses to view wildlife. I was particularly grateful to see a wolf: sightings are now rare, owing to a dramatic population decline in the past five years. This can be attributed to hunting on the Park boundaries in State,as opposed to Federal, land. The wolf pictured below has a radio collar, as do all the pack leaders in Denali, so they can be tacked for research purposes, but in spring 2015 only 48 wolves survived in the entire park.
