The '''Thwaites Glacier''' (75°30′S 106°45′W), including the '''Thwaites Ice Tongue''', is an unusually broad and fast Antarctic [[glacier]] flowing into [[Pine Island Bay]], part of the [[Amundsen Sea]], east of [[Mount Murphy]], on the [[Walgreen Coast]] of [[Westarctica]]. Its surface speeds exceed 2 km/yr near its grounding line, and its fastest flowing grounded ice is centered between 50 and 100 km east of [[Mount Murphy]]. It was named after Fredrik T. Thwaites, a glacial geologist, geomorphologist and professor emeritus at the University of Wisconsin–Madison.
'''[[Dorrel Rock]]''' is a rock outcrop 11 nautical miles (20 km) southwest of the summit of [[Mount Murphy]], protruding through the ice near the head of [[Pope Glacier]], on the [[Walgreen Coast]] in [[Westarctica]]. It was mapped by the United States Geological Survey from surveys and [[U.S. Navy]] air photos, 1959–66, and was named by the Advisory Committee on [[Antarctic]] Names after Leo E. Dorrel, U.S. Navy, a hospital corpsman with the [[Byrd Station]] winter party, 1966. On 2 November 2018, Westarctica's [[Honorary Consular Corps|Honorary Consul]] to Spain, [[Baron of Dorrel|Dr. Joachim Michael Adlfinger]], was granted the [[Peerage of Westarctica|Peerage title]] of Baron of Dorrel in recognition of his successful opening of Westarctica's consulate office in southern Spain.


Along with the [[Pine Island Glacier]], the Thwaites Ice Tongue has been described as part of the "weak underbelly" of the [[West Antarctic Ice Sheet]], due to its apparent vulnerability to significant retreat. This hypothesis is based on both theoretical studies of the stability of marine ice sheets and recent observations of large changes on both of these glaciers. In recent years, the flow of both of these glaciers have accelerated, their surfaces lowered, and the grounding lines retreated.

Dorrel Rock - Mt. Murphy.jpg

Dorrel Rock is a rock outcrop 11 nautical miles (20 km) southwest of the summit of Mount Murphy, protruding through the ice near the head of Pope Glacier, on the Walgreen Coast in Westarctica. It was mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1959–66, and was named by the Advisory Committee on Antarctic Names after Leo E. Dorrel, U.S. Navy, a hospital corpsman with the Byrd Station winter party, 1966. On 2 November 2018, Westarctica's Honorary Consul to Spain, Dr. Joachim Michael Adlfinger, was granted the Peerage title of Baron of Dorrel in recognition of his successful opening of Westarctica's consulate office in southern Spain.
