A glacial meltwater stream which flows south along the east margin of Canada Glacier into the west end of Lake Fryxell.

The name was suggested by hydrologist Diane McKnight, leader of a USGS team which made extensive studies of the hydrology and geochemistry of streams and ponds in the Lake Fryxell basin, 1987–94.

Named after USGS hydrologist Edmund Andrews, a member of the field team who studied glacier hydrology during the 1987–88 and 1991–92 summer seasons.

A glacial meltwater stream, 1.2 nautical miles (2.2 km; 1.4 mi) long, flowing south from an ice field west of Mount Falconer to the north-central shore of Lake Fryxell.

The name was suggested by hydrologist Diane McKnight, leader of a USGS team that made extensive hydrological studies in the Lake Fryxell basin, 1987–94.

The name acknowledges support received by the USGS field team in Taylor Valley from United States Navy Squadron VXE-6 and its twin engine UH-1N "Huey" helicopters.

Glacier which flows in a southeast direction and enters the north side of Taylor Valley immediately west of Mount Coleman.

Named for the Commonwealth of Australia, which made a financial grant to the BrAE and contributed two members to the Western Geological Party which explored this area.

A glacial meltwater stream, 1.4 nautical miles (2.6 km; 1.6 mi) long, draining from the west margin of Commonwealth Glacier into the northeast end of Lake Fryxell.

The name was suggested by Diane McKnight, leader of a USGS team that studied the hydrology of streams flowing into Lake Fryxell in several seasons, 1987–94.

Studied on the ground during United States Navy Operation Depp Freeze, 1957–58, by Troy L. Péwé who suggested the name in association with Commonwealth Glacier.

The name was suggested by Diane McKnight, leader of a USGS team which made extensive studies of the hydrology and geochemistry of streams and ponds in the Lake Fryxell basin, 1987–94.

A glacial meltwater stream, 2.6 nautical miles (4.8 km; 3.0 mi) long, flowing north from Crescent Glacier to the south-central shore of Lake Fryxell.

The name was suggested by hydrologist Diane McKnight, leader of a USGS team that made extensive studies of the hydrology and geochemistry of streams and ponds in the Lake Fryxell basin, 1987–94.

The name was suggested by Diane McKnight, leader of USGS teams which made extensive studies of the hydrology of streams in the Lake Fryxell basin, 1987–94.

A glacial meltwater stream, 0.5 nautical miles (0.93 km; 0.58 mi) long, which flows from the snout of Canada Glacier.

The name was suggested by Diane McKnight, USGS hydrologist working in the Lake Fryxell basin, 1987–94, and alludes to the many aeolian deposits of fine sands along the creek, indicative of strong winds blowing around the south end of Canada Glacier during the winter.

Named from "They Called the Wind Maria," a song in Paint Your Wagon, the American musical play by Lerner and Loewe.
