Mount Blackburn is the highest peak in the Wrangell Mountains of Alaska in the United States. It is the fifth-highest peak in the United States and the twelfth-highest peak in North America. The mountain is an old, eroded shield volcano, the second-highest volcano in the U.S. behind Mount Bona and the fifth-highest in North America. It was named in 1885 by Lt. Henry T. Allen of the U.S. Army after Joseph Clay Stiles Blackburn, a U.S. senator from Kentucky. It is located in the heart of Wrangell – St. Elias National Park, the largest national park in the country.
Mount Sanford is a shield volcano in the Wrangell Volcanic Field, in eastern Alaska near the Copper River. It is the sixth highest mountain in the United States and the third highest volcano behind Mount Bona and Mount Blackburn. The south face of the volcano, at the head of the Sanford Glacier, rises 8,000 feet (2,400 m) in 1 mile (1,600 m) resulting in one of the steepest gradients in North America.
Mount Iliamna is a glacier-covered stratovolcano in the largely volcanic Aleutian Range in southwest Alaska. Located in the Chigmit Mountain subrange in Lake Clark National Park and Preserve, the 10,016-foot (3,053 m) volcano lies approximately 134 miles (215 km) southwest of Anchorage on the west side of lower Cook Inlet. It is the 25th most prominent peak in the United States.
The Ivishak River is a 95-mile (153 km) tributary of the Sagavanirktok River in the North Slope Borough of the U.S. state of Alaska. Fed by glaciers at the headwaters, the Ivishak flows northeast, then northwest, through the Philip Smith Mountains and the northern foothills of the Arctic National Wildlife Refuge. It enters the Sagavanirktok River on the coastal plain south of Prudhoe Bay.

It was named after Johns Hopkins University in Baltimore, Maryland in 1893 by Harry Fielding Reid. It is one of the few advancing tidewater glaciers of the Fairweather Range. Access to the face of the glacier is limited to the Johns Hopkins Inlet.
Clark Glacier is an 8-mile (13 km) long glacier located on Mount Abbe in Glacier Bay National Park and Preserve in the U.S. state of Alaska. It leads northwest to its 1961 terminus at the head of Johns Hopkins Inlet, 78 mi (126 km) northwest of Hoonah, Alaska. It was named by W. O. Field and W. S. Cooper in 1936 for Johns Hopkins University professor of geology William Bullock Clark (1860–1917).
The Knik River (Dena'ina: Skitnu) is a 25-mile-long (40 km) river in the U.S. state of Alaska. Its source is at Knik Glacier, from which it flows northwest and west and empties into the head of Cook Inlet's Knik Arm, near the mouth of the Matanuska River. It is bridged twice where the Old Glenn Highway crosses it near the Butte, and also bridged on the Hayflats.
Carbon Glacier is located on the north slope of Mount Rainier in the U.S. state of Washington and is the source of the Carbon River. The snout at the glacier terminal moraine is at about 3,500 feet (1,100 m) above sea level, making it the lowest-elevation glacier in the contiguous United States. The glacier also has the greatest length, thickness and volume of any U.S. glacier outside of Alaska.
Bryn Mawr Glacier is a 4.5-mile-long (7.2 km) glacier in the U.S. state of Alaska. It trends southeast to Harvard Arm of College Fjord, 2 miles (3.2 km) northwest of College Point and 52 miles (84 km) west of Valdez. It was named for Bryn Mawr College in Bryn Mawr, Pennsylvania by members of the 1899 Harriman Alaska Expedition.
Crescent Glacier is a 5.5-mile-long (9 km) glacier in the U.S. state of Alaska. It trends northwest on the east bank of College Fjord, 55 miles (89 km) west of Valdez. It was named by members of the 1899 Harriman Alaska Expedition.
The Dartmouth Glacier is a 3.4-mile (5.5 km)-long glacier in the U.S. state of Alaska. It heads southwest of Mount Castner in the Chugach Mountains and trends southwest to its terminus at the head of the Coghill River, 47 miles (76 km) west of Valdez. The name was reported in 1908 by Grant and Higgins, USGS. It is presumably named for Dartmouth College in Hanover, New Hampshire.
Downer Glacier is a 2.6-mile-long (4.2 km) glacier in the U.S. state of Alaska. Trends west with a length of 2.6 mi (4.2 km), in Kora Keen Range, 46 mi (74 km) northwest of Valdez. It was named in 1910 by Lawrence Martin for the Milwaukee-Downer College for Women in Milwaukee, Wisconsin.

It was named for Smith College in Northampton, Massachusetts by members of the 1899 Harriman Alaska Expedition.
Williams Glacier is a 1.2-mile (1.9 km) long glacier in the U.S. state of Alaska. It trends northwest to its terminus 4.5 mi (7.2 km) east of College Point and 50 mi (80 km) west of Valdez. The name was reported in 1908 by Grant and Higgins, USGS. It was named for Williams College in Williamstown, Massachusetts.
Amherst Glacier is a 4-mile-long (6.4 km) glacier in the U.S. state of Alaska. It trends northwest to a lake, 5.5 mi (8.9 km) northeast of Point Pakenham and 52 mi (84 km) southwest of Valdez.

Macy Glacier is a 3.7 nautical miles long and 1.4 nautical miles crescent-shaped glacier on the southern slopes of the Tangra Mountains, Livingston Island in the South Shetland Islands, Antarctica. The glacier is bounded by Friesland Ridge to the northwest, Levski Ridge to the northeast and Peshev Ridge to the southeast, and flows southwestwards into the head of Brunow Bay.
Mount Witherspoon is a 12,012-foot-elevation glaciated summit located 36 mi (58 km) northwest of Valdez in the Chugach Mountains of the U.S. state of Alaska. It's set on land managed by Chugach National Forest. This remote mountain, fifth-highest in the Chugach range, is situated 4.33 mi (7 km) northwest of Mount Einstein, with the heads of Yale Glacier and Columbia Glacier between the summits. It is the second-highest peak in the Dora Keen Range, which is the 25-miles-long divide separating Harvard Glacier from Yale Glacier. The mountain's name was officially adopted in 1928 by the U.S. Board on Geographic Names to honor David C. Witherspoon, a U.S. Geological Survey topographer for 30 years, "who at the time of his retirement in 1921 had mapped a greater area of Alaska than any other man." The first ascent of Mount Witherspoon was made June 25, 1957, by David Bohn, Arthur Maki, Jr., Martin Mushkin, and Lawrence E. Nielsen.
