Denali National Park and Preserve

[edit]

Nikolai, Telida, Lake Minchumina, and Cantwell residents are authorized to hunt inside the park because large portions of these communities historically hunted in the area for subsistence purposes[1].


There are several non-native species in the park including common dandelion, narrowleaf hawksbeard, white sweet clover, bird vetch, yellow toadflax, and scentless false mayweed[2][3]. There are 28 invasive species documented in the park and 15 of these species are considered a threat[2]. Volunteers and park rangers work to keep non-native plant populations low[2].

Glaciers

[edit]

Measurements indicate that glaciers in the park are losing about 6.6ft (2m) of vertical water equivalency each year[4].

Permafrost

[edit]

Permanently frozen ground is known as permafrost. The permafrost is discontinuous in Denali due to differences in vegetation, temperatures, snow cover and hydrology[5]. The active layer freezing and thawing seasonally can be from 1 inch (25 mm) to 10 feet (3.0 m) thick. The permafrost layer is located at between 30 and 100 feet (9.1 and 30.5 m) below the active layer. A stand of oddly leaning white spruce growing on a lower slope of Denali is called the Drunken Forest. The trees lean due to the soil sliding as a result of permafrost freeze/thaw cycles. Permafrost impacts the ecosystem in the park by influencing hydrology, patterns of vegetation, and wildlife[6].

During the very cold Pleistocene climates, all of Denali was solidly frozen[7]. The northern areas of the range are still frozen due to continued cold temperatures. About 75% of Denali had near-surface permafrost, or an active permafrost layer, in the 1950s[8]. In the 2000s, around 50% of Denali had near-surface permafrost. It is suspected that by the 2050s, only about 6% of surface permafrost will remain. Because of climate change, most of the shallow permafrost is thawing. It is estimated that with an addition 1-2 degree warming, most of Denali's permafrost will thaw[9]. Permafrost thaw causes landslides as the ice rich soil transforms into mud slurry[10]. Landslides have previously impacted accessibility in Denali by obstructing the roads in the park[11]. Permafrost thaw releases addition carbon into the atmosphere[12].

Rules and Regulations

[edit]

General

[edit]
Picnic near Denali National Park and Preserve in June, 2013.

There are no restrictions on walking, hiking, or picnicking.[13] Group sizes must consist of 12 or less individuals including guides in backcountry units 1-21, 23-47, 61-64, 70-79, 81, 86, 87 on the east side of the park and 6 or less individuals in backcountry units 22, 48, 65-69, 80, 82-85 on the west side of the park.[13] Possession or use of marijuana and other controlled substances are prohibited within all national parks, preserves, rivers, and monuments.[14]

E-bikes are permitted in the park on trails open to traditional bicycles, park roads, and parking areas.[13] Where traditional bicycles are prohibited, e-bikes are also prohibited with the exception of where public motor vehicles are allowed.[13]

Camping

[edit]

Camping is allowed in designated park areas for a time of up to 14 consecutive days.[15] Visitors can also choose to camp in designated backcountry units for up to 30 days with a limit of 7 days in a unit per trip between April 15 and September 30.[13] Riley Creek, Savage River, and Teklanika River Campgrounds are where fires can be lit and maintained.[13] If any rocks are moved to create fire-pits, following the extinguishment of the fire, they must be returned to their original locations, and all trash, including burned food, glass, and cans, must be properly disposed of.[13]

Mountain climbing in Denali National Park and Preserve.

Mountain Climbing

[edit]

Those who wish to mountain climb on Denali and Mt. Foraker must obtain a climbing permit at least 60 days prior to the start of the climb.[13] In addition to obtaining a permit, solo climbers must also submit a Supplemental Solo Form.[13] Climbers must check in before and after their climb at the Walter Harper Talkeetna Ranger Station with their expedition group and attend a mandatory safety orientation and learn about resource protection prior to climbing.[13]

Gathering and Collecting

[edit]

Visitors are allowed to collect unendangered natural foods including fruits and berries, uninhabited seashells, surface rocks and minerals, and dead wood as campfire fuel.[15] Visitors may not collect silver, gemstones, or fossils. All gathering and collecting must be done by hand and cannot use shovels, pickaxes, or anything that will disturb the ground surface.[15]

Hunting and Fishing

[edit]

Sport hunting is permitted within Denali National Preserve but prohibited within all areas of Denali National Park.[16] Some local rural residents over the age of 18 with a valid Alaska State hunting license are permitted to subsistence hunt on lands added by the Alaskan National Interest Conservation Act.[16] Visitors may fish in all park areas in accordance with applicable State and Federal law.[15]
