The Lehrke Inlet of the Weddell Sea is on the east coast of Palmer Land, at the north end of the Black Coast of the Antarctic Peninsula. It is south of the Eielson Peninsula and Dolleman Island, and north of the Imshaug Peninsula and Steele Island. The Eland Mountains are to the northwest and the Welch Mountains are to the west-southwest. Glaciers feeding the inlet include, clockwise from the south, Gain Glacier, Dana Glacier, Yates Glacier, Matheson Glacier and Ashton Glacier. Other features include Cape Boggs, Cape Sharbonneau, Mount Hill on the Imshaus Peninsula, Neilson Peak on the Parmalee Massif, and Dawson Head.

## Discovery and name

Lehrke Inlet was discovered by members of the United States Antarctic Service (USAS) who explored this coast on land and from the air in 1940. It was named for Lester Lehrke, boatswain's mate of USS Bear, one of the expedition ships, and sailmaker of the East Base.

### Dana Glacier

70°55′S 62°23′W﻿ / ﻿70.917°S 62.383°W﻿ / -70.917; -62.383. A glacier about 30 nautical miles (56 km; 35 mi) long. It drains the slopes at the southeast side of the Welch Mountains and flows east then northeast to discharge into the head of Lehrke Inlet just north of Parmelee Massif. Mapped by the United States Geological Survey (USGS) in 1974. Named by the United States Advisory Committee on Antarctic Names (US-ACAN) for Commander John B. Dana, United States Navy, Commanding Officer of United States Navy Squadron VXE-6 in Antarctica during Operation Deep Freeze, 1973; he was squadron Executive Officer, 1972, and Operations Officer, 1971.

### Yates Glacier

Named by the UK Antarctic Place-Names Committee (UK-APC) after J. Yates, British Antarctic Survey (BAS) surveyor who worked in the general vicinity of this feature.

### Matheson Glacier

70°47′S 62°05′W﻿ / ﻿70.783°S 62.083°W﻿ / -70.783; -62.083. A glacier 11 nautical miles (20 km; 13 mi) long, lying 2 nautical miles (3.7 km; 2.3 mi) south of Ashton Glacier, which it parallels, and flowing in an east direction to the west side of Lehrke Inlet. First sighted by members of the USAS who explored this coast by land and from the air in December 1940. First charted by a joint party consisting of members of the Ronne Antarctic Research Expedition (RARE) and Falkland Islands Dependencies Survey (FIDS) in 1947. Named by the FIDS for J. Matheson, a member of the FIDS at the Port Lockroy and Hope Bay bases, 1944-46.

### Ashton Glacier

70°44′S 61°57′W﻿ / ﻿70.733°S 61.950°W﻿ / -70.733; -61.950. A glacier 9 nautical miles (17 km; 10 mi) long, which flows east-southeast from Mount Thompson to the northwest side of Lehrke Inlet, on the east coast of Palmer Land. The glacier was photographed from the air in December 1940 by the USAS, and was probably seen by the USAS ground survey party which explored this coast. A joint party consisting of members of the RARE and the FIDS charted the glacier in 1947. Named by the FIDS for L. Ashton, carpenter with the FIDS at the Port Lockroy and Hope Bay bases in 1944-45 and 1945-46, respectively.
