The greater white-fronted goose is a species of goose related to the smaller lesser white-fronted goose. It is named for the patch of white feathers bordering the base of its bill, in fact albifrons comes from the Latin albus "white" and frons" forehead ". In Europe it has been known as the "white-fronted goose"; in North America it is known as the greater white-fronted goose, and this name is also increasingly adopted internationally. Even more distinctive are the salt-and-pepper markings on the breast of adult birds, which is why the goose is colloquially called the "specklebelly" in North America.

Chugach State Park covers 495,204 acres immediately east of the Anchorage Bowl in south-central Alaska. Though primarily in the Municipality of Anchorage, a small portion of the park north of the Eklutna Lake area in the vicinity of Pioneer Peak lies within the Matanuska-Susitna Borough. Established by legislation signed into law on August 6, 1970, by Alaska Governor Keith Miller, this state park was created to provide recreational opportunities, protect the scenic value of the Chugach Mountains and other geographic features, and ensure the safety of the water supply for Anchorage. The park, managed by Alaska State Parks, is the third-largest state park in the United States, and consists of geographically disparate areas each with different attractions and facilities. Only Anza-Borrego Desert State Park in California and Wood-Tikchik State Park in western Alaska are larger. Hunting and fishing are permitted in the Chugach under regulations established by the Alaska Department of Fish and Game for game management unit 14c. Target practice is not allowed within the park boundaries.

It is an extremely high-prominence summit, with a difference in elevation with its "key col" at Hyland Ranch Pass of 2,430 m (7,972 ft). Thus making it one of Canada's Ultra peaks.
