The great mountain and its companion peaks are accented by spectacular valley glaciers and steep ice-carved gorges and a year-around mantle of snow and ice above 8,000 feet. These glaciers, such as the Ruth, Buskin, and Eldridge, are from 14 to 38 miles long and up to four miles wide. They flow from the high peaks and melt into the broad U-shaped Chulitna Valley, giving the Chulitna River the milky waters and braided channels that are typical of a glacial stream. Though only 35 miles from the summit of Mt. McKinley, the flood plain of the Chulitna is but 550 feet in elevation.

Denali State Park has superb vantage points for viewing the breathtaking heart of the Alaska Range. Perhaps the best roadside view anywhere of the Alaska Range is at mile 135.2 Parks Highway. An interpretive bulletin board at this site names the mountains and other terrain features. Other excellent views of Mt. McKinley along the highway are at mile 147.1, 158.1, and 162.3. Day hikers on Kesugi Ridge or backpackers in the Peters Hills in the western end of the park have an unencumbered view of the Denali massif that is almost overwhelming in grandeur.

The beauty of McKinley and the Alaska Range from the Peters Hills was captured on large canvas oil paintings by preeminent Alaskan artist Sydney Laurence in the early part of this century. When the railroad trip from Seward and Anchorage to Fairbanks took two days, travelers in the early 1900's sometimes stayed an extra day at Curry to ascend the east side of Curry Ridge and gaze upon Mt. McKinley and its wonders from Curry Lookout. This small hexagonal-shaped building still weathers storms on the ridge.

From the alpine tundra of Curry Ridge to the river bottoms of the meandering Tokositna River, the park's varied landscape is home to a diverse array of wildlife. Moose, as well as grizzly and black bears, are found throughout the park. Though seldom seen, the wolf frequents much of the park, and caribou occasionally reach the park's northern end. Smaller, elusive residents include lynx, coyote, red fox, snowshoe hare, land otter, and flying and red squirrel. The weasel family is well represented by ermine, marten, mink and wolverine. Wet areas are habitat for muskrat and beaver, while pika and marmot may be found in rocky areas above timberline. Porcupine will be glad to browse through your food box for salt. Several species of vole and shrew make their minute paths throughout the park.

The tapestry of habitats in the park yield an especially rich bird community. More than 130 species use the park for breeding or during migration. Year-round residents include the ubiquitous common raven, his cousin the gray jay, willow ptarmigan (the state bird), and acrobatic flocks of black-capped and boreal chickadees. However, most birds migrate long distances to frequent the park. The champion marathoner of the bird world, the arctic tern, flies some 12,000 miles to breed in Denali, repeating the journey to winter in the Antarctic. A shorebird, the lesser golden plover, nests on the alpine tundra after wintering in faraway Polynesia. Water birds such as the rare, majestic trumpeter swan, the common loon with its hunting call, and the fish-eating osprey are attracted to the park's myriad lakes and streams. Early on a June morning, the woods and ridges are alive with the ringing of bird song as a host of small birds, like the golden-crowned sparrow, Wilson's warbler, and ruby-crowned kinglet, proclaim their territories.
