Taylor Valley

Taylor Valley -77.61667°N, 163°W is an ice-free valley about 18 nmi long, once occupied by the receding Taylor Glacier. It lies north of the Kukri Hills between the Taylor Glacier and New Harbour in Victoria Land, Antarctica. Taylor Valley is the southernmost of the three large McMurdo Dry Valleys in the Transantarctic Mountains, located west of McMurdo Sound.

Exploration and naming
The Taylor Valley was discovered by the British National Antarctic Expedition (BrNAE, 1901–04). It was more fully explored by the British Antarctic Expedition, 1907–09 (BrAE) and the British Antarctic Expedition, 1910–13. It was named after the Taylor Glacier.

Geology
In the oblique aerial photo at right, the tan bands are sandstone layers from the Beacon Supergroup, a series of sedimentary rock layers formed at the bottom of a shallow sea between 250 million and 400 million years ago. Throughout that period, Earth's southern continents were locked into the supercontinent Gondwana.

The dark band of rock that divides the sandstone is dolerite (sometimes called diabase), a volcanic rock that forms underground. The distinctive dolerite intrusion—or sill—is a remnant of a massive volcanic plumbing system that produced major eruptions about 180 million years ago. The eruptions likely helped tear Gondwana apart.

Location
Taylor Valley is one of the McMurdo Dry Valleys. Parts of the area were visited by British expeditions led by Captain Robert Falcon Scott (1901–04 and 1910–13), who referred to Taylor Valley, as well as Beacon Valley and Pyramid Trough (named later), as "dry valleys." It runs from the east end of Taylor Glacier to New Harbour in McMurdo Sound. It separates the Kukri Hills to the south from the Asgard Range to the north.

Features
Features of the valley include, from west to east, Bonney Riegel below Mount J. J. Thomson, Lake Bonney, Nussbaum Reigel, Mummy Pond, Lake Chad, Andrews Ridge and Lake Frysell, which is fed by the Delta Stream from the south.
