Disco is shorthand for Discovery Hike, a hike that is planned by a ranger, transects a selected area of the wilderness and is charted so that no more than two hikes can be made in that same area during a single summer season.

Besides the goal of offering guided hikes to educate visitors, these hikes are designed to protect the integrity of the wilderness and create the least amount of impact to the plant and animal communities in the tundra. There are a limited number of established trails in the park; the remainder of visitor hiking is done off trail in the wilderness by permit.

September is a beautiful time in Denali. The tundra is vibrant with fall foliage, brilliant in color and ever changing weather conditions and lighting. Every step brings more breath-taking beauty and discovery, and it is especially exciting to experience some of the plants in the tundra up close.
September 3rd was my second day in the park with Rangers Bob and Tina King as my host and hostess during my stay. Our forecast for this hike was light rain, winds gusting to 60 mph and temps in the 40's F. You can see we are bundled up, primarily to block the wind. Fortunately, the rain remained misty, giving us very tolerable conditions.
We are headed for that distant shelf ridge you see in the above images, to rest for lunch along its edge and enjoy the view created by the glacial rivers. Along the way we stopped to sample the wild bog blueberries.
The height of tundra vegetation is limited by the depth of the soil. Below the soil lies perma frost, a layer of ice that remains year around, partially melting during summer months and refreezing during the winter. Growth height is also determined by genetic properties that keep the plant from growing high enough to be damaged by the winds that blow across the tundra. I had the good fortune of not only sampling tundra blueberries but also enjoying their tasty tartness over pound cake with fresh whipped cream at a cordial dinner in Fairbanks a few days earlier. Yum!

We had a descent and a river to cross. Thanks to the watchful eyes of our leader, we paused and got some good looks at willow ptarmigans foraging under the willow branches.
