Exploring the Last Frontier at Gates of the Arctic National Park

POSTED ON May 20, 2020 BY Ralph S.


Welcome to the Gates of the Arctic National Park, the northernmost national park located in Alaska’s Brooks mountain ranges. Managed by the National Park Service, this vast wilderness park covers over 8 million acres (about 34,000 km2) of pristine arctic wilderness. Its untouched beauty and diverse landscapes make it a must-visit destination for nature lovers and adventure seekers alike.

Located within the Arctic Circle and sharing borders with Kobuk Valley National Park, Noatak National Preserve, and the Arctic National Wildlife Refuge, this remote park lies in northern Alaska’s Brooks Range. From glacier-carved valleys to rugged mountains, the Gates of the Arctic offer a stunning landscape that is home to a variety of wildlife, including bears and Dall sheep.

One of its unique features is the presence of wild rivers that meander through the park, making it a popular destination for rafting and kayaking. The North Fork of the Koyukuk River and other scenic rivers provide visitors with an unforgettable experience of traversing through this untouched wilderness.

Access to this national monument is limited, with no roads or trails leading in. However, adventurous travelers can take a scenic drive on the Dalton Highway, also known as “The Haul Road,” to get a glimpse of the park’s western Arctic region. The central Brooks Range and Noatak Wilderness can be explored by air or foot.

Join us on this journey to explore the last frontier at Gates of the Arctic National Park and Preserve, where you’ll discover why it is regarded as one of the crown jewels of the National Park System.

The Gates of the Arctic National Park holds a significant place in Alaska’s national interest, as it is one of the state’s most remote national parks.

The genesis of this remote national park can be traced back to the passage of the Alaska National Interest Lands Conservation Act (ANILCA) in 1980. This landmark legislation not only expanded the National Park System but also recognized the significance of preserving vast, untouched wilderness areas.

The park initially covered over two million acres (about 8,000 sq km), but with subsequent expansions, it now spans over 8 million acres. It is managed by the National Park Service (NPS) and is a vital part of the National Wild and Scenic Rivers System.

The Gates of the Arctic National Park Preserve is home to age-old trails used by Native Alaskans for over ten thousand years. These trails served as important trade routes and were also used for hunting, fishing, and gathering resources. The park’s glacier-carved valleys and wild rivers meander through this vast landscape.

In the early 1900s, the Ambler Mining District was established in the western region of the park. Miners came to the area in search of gold and copper, leaving behind traces of their activity. However, due to the park’s remote location and harsh winters, mining operations were never successful.

Today, visitors can still find remnants of these mining activities while exploring the park. The North Fork of the Koyukuk River is a prime spot for fishing, and it flows through the Ambler Mining District. Its pristine waters and intact ecosystems offer visitors a glimpse of the park’s past and present.

The Gates of the Arctic National Park Preserve continue to remain virtually unchanged, providing a unique opportunity for visitors to experience true wilderness. Thanks to the collaborative efforts of the NPS, Alaska Alpine Adventures, and other organizations, this national park remains protected for future generations to enjoy.
