Connell Pond
Connell Pond () is a freshwater frozen pond in the Labyrinth of Wright Valley, McMurdo Dry Valleys. The pond lies in Healy Trough, south of Rodriquez Pond. It was named by the Advisory Committee on Antarctic Names (2004) after Laurie Connell of the University of Maine, the leader of a United States Antarctic Program The United States Antarctic Program (or USAP; formerly known as the United States Antarctic Research Program or USARP and the United States Antarctic Service or USAS) is an organization of the United States government which has presence in the A ... field party that sampled the pond in 2003–04.

Labyrinth (Antarctica)
The Labyrinth () is an extensive flat upland area which has been deeply eroded, at the west end of Wright Valley, in Victoria Land, Antarctica. It was so named by the Victoria University of Wellington Antarctic Expedition (1958–59) because the eroded dolerite of which it is formed gives an appearance of a labyrinth.

Wright Valley
The Wright Valley, named for Sir Charles Wright, is the central one of the three large Dry Valleys in the Transantarctic Mountains, located west of McMurdo Sound at approximately . Wright Valley contains the Onyx River, the longest river in Antarctica, Lake Brownworth, the origin of the Onyx River, and Lake Vanda, which is fed by the Onyx River. Its southwestern branch, ''South Fork'', is the location of Don Juan Pond. The upland area known as the Labyrinth is at the valley's west end. Although portions of the interconnected valley system were discovered in 1903 by the ''Discovery'' expedition led by Captain Robert Falcon Scott, the Wright Valley located near the centre of the system was not seen until aerial photographs of the region were made in 1947. By the mid 1960s scientists were becoming increasingly intrigued by the paradoxical fact that the valley lay immediately adjacent to the permanent East Antarctic Ice Sheet, yet had remained ice-free for at least thousands o ...

McMurdo Dry Valleys
The McMurdo Dry Valleys are a row of largely snow-free valleys in Antarctica, located within Victoria Land west of McMurdo Sound. The Dry Valleys experience extremely low humidity and surrounding mountains prevent the flow of ice from nearby glaciers. The rocks here are granites and gneisses, and glacial tills dot this bedrock landscape, with loose gravel covering the ground. It is one of the driest places on Earth and has not seen rain for nearly two million years. The region is one of the world's most extreme deserts, and includes many features including Lake Vida, a saline lake, and the Onyx River, a meltwater stream and Antarctica's longest river. Although no living organisms have been found in the permafrost here, endolithic photosynthetic bacteria have been found living in the relatively moist interior of rocks, and anaerobic bacteria, with a metabolism based on iron and sulfur, live under the Taylor Glacier. The valleys are located within the McMurdo Valleys A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
