Story of the Byway

Alaska’s Glenn Highway boasts the largest collection of glaciers of any US National Park, in Wrangell-St. Elias National Park. Winters present you with a splendid sky show when the Northern Lights dance among the snow-capped mountains, while summers bring you endless days to roam in fields of wildflowers and ancient forests.The route on Highway 1 begins near Glennallen and the Tazlina River at the north end and culminates in Anchorage to the southwest. Anchorage is located within Dena’ina Etnena, on the traditional homelands of the Deena’ina Athabascan people and the Native Village of Eklutna. The city combines the beauty of the Alaska wilderness with urban comforts and outdoor spaces. Native American Culture is a big part of the Glenn Highway story, as well as the Alaska story. Some of these groups are unique to Alaska, making their story nationally significant.
