Augustine Volcano (Sugpiaq: Utakineq; Dena'ina: Chu Nula) is a stratovolcano in Alaska consisting of a central complex of summit lava domes and flows surrounded by an apron of pyroclastic, lahar, avalanche, and ash deposits. The volcano forms Augustine Island, colloquially called Mount St. Augustine, in southwestern Cook Inlet in the Kenai Peninsula Borough of southcentral coastal Alaska, about 70 miles (113 km) west of Homer and about 175 miles (282 km) southwest of Anchorage.

The volcano is frequently active, with major eruptions recorded in 1883, 1935, 1963–64, 1976, 1986, and 2006. Minor eruptive events were reported in 1812, 1885, 1908, 1944, and 1971. The large eruptions are characterized by an explosive onset followed by the quieter effusion of lava. Augustine Island has a land area of 32.4 square miles (83.9 km), while West Island, just off Augustine's western shores, has 2 sq mi (5.2 km). The irregular coastline of Augustine Island is due to the repeated catastrophic collapse of the summit dome, forming debris avalanches down the flanks and into Cook Inlet.

The Kenai Peninsula (Dena'ina: Yaghenen) is a large peninsula jutting from the coast of Southcentral Alaska. The name Kenai (/ˈkiːnaɪ/, KEE-ny) is derived from the word "Kenaitze" or "Kenaitze Indian Tribe", the name of the Native Athabascan Alaskan tribe, the Kahtnuht’ana Dena’ina ("People along the Kahtnu (Kenai River)"), who historically inhabited the area. They called the Kenai Peninsula Yaghanen ("the good land").

Knik Arm (Dena'ina: Nuti) is a waterway into the northwestern part of the Gulf of Alaska. It is one of two narrow branches of Cook Inlet, the other being Turnagain Arm. Knik Glacier empties into the Knik Arm. The Port of Anchorage is located on the arm.

Turnagain Arm (Dena'ina: Tutl'uh) is a waterway into the northwestern part of the Gulf of Alaska. It is one of two narrow branches at the north end of Cook Inlet, the other being Knik Arm. Turnagain is subject to climate extremes and large tide ranges.

Ship Creek (Dena'ina: Dgheyaytnu) is an Alaskan river that flows from the Chugach Mountains into Cook Inlet. The Port of Anchorage at the mouth of Ship Creek gave its name ("Knik Anchorage") to the city of Anchorage that grew up nearby.

The river lies entirely within the limits of the Municipality of Anchorage, Alaska. Most of its upper length traverses Joint Base Elmendorf-Richardson.

Homer (Dena'ina: Tuggeght) is a city in Kenai Peninsula Borough in the U.S. state of Alaska. It is 218 mi (351 km) southwest of Anchorage. According to the 2020 census, the population was 5,522, up from 5,003 in 2010. Long known as the "Halibut Fishing Capital of the World", Homer is also nicknamed "the end of the road", and more recently, "the cosmic hamlet by the sea".

Seward (Alutiiq: Qutalleq; Dena'ina: Tl'ubugh) is an incorporated home rule city in Alaska, United States. Located on Resurrection Bay, a fjord of the Gulf of Alaska on the Kenai Peninsula, Seward is situated on Alaska's southern coast, approximately 120 miles (190 km) by road from Alaska's largest city, Anchorage.

With a population of 2,717 people as of the 2020 census, Seward is the fourth-largest city in the Kenai Peninsula Borough, behind Kenai, Homer, and the borough seat of Soldotna. The city is named for former United States Secretary of State William H. Seward, who orchestrated the United States' purchase of Alaska from the Russian Empire in 1867 while serving in this position as part of President Andrew Johnson's administration.

The Kenai Mountains (Dena'ina: Yaghanen Dghili) are a mountain range in the U.S. state of Alaska. They extend 120 miles (190 km) northeast from the southern end of the Kenai Peninsula to the Chugach Mountains, and have an average elevation of 3,000 to 5,000 feet.

The Harding and Sargent Icefields, as well as the many glaciers that emanate from them, originate in the Kenai Mountains. Several prime fish-producing rivers, including the Kenai River and the Russian River, also flow from the mountains.
