"Lake Bonney","Taylor","77-43 S","162-20 E",25,57,7,0.9,40,4.3,"2.8 - 4.5",64.8,"Lake Bonney occupies a glacially scoured bedrock basin in Taylor Valley. It is located at the head of the valley and is perennially ice-covered. The lake has two basins (lobes) connected by a narrow, shallow channel. There are no surface outflows; the only known water loss is through ice ablation (evaporation, sublimation and physical scouring). The lake is bordered to the north by the Asgard Range and to the south by the Kukri Hills. Mountain and cirque glaciers occupy hanging valleys between these peaks and supply meltwater intermittently to the lake during warmer periods in summer. The largest source of meltwater, however, is from the Taylor Glacier, which extends from the polar ice-cap and terminates in the western end of the west lobe of Lake Bonney." "Lake Fryxell","Taylor","77-37 S","163-09 E",9,18,5.8,2.1,20,7.08,"3.3 - 4.5",25.2,"The Lake Fryxell basin is formed by a moraine depression in a wider portion of the Taylor Valley. It has a number of moraine islands and shallower areas, as well as several relatively well developed deltas. The lake is fed by at least 10 meltwater streams with a total drainage catchment of 230 km2. The lake is dammed to the southwest by the Canada Glacier and is topographically closed. It is perennially ice covered; during summer months, an ice-free moat generally forms around much of the lake margin. Lake levels have risen ~2 m between 1971 and 1996. There are no surface outflows; the only known water loss is through ice ablation (evaporation, sublimation and physical scouring)."

It would drain almost completely without this dam. There are a number of islands which may be related to an old terminal of Canada Glacier. The lake is fed primarily from direct runoff from the glacier, as well as meltwater streams. (Lake level rose ~1.5 m between 1972 and 1996). There are no surface outflows; the only known water loss is through ice ablation (evaporation, sublimation and physical scouring)."

It is wedged between the Asgard Range and the Dias. On the west end there is a small tributary and a feature that has been described as a rock glacier. Don Juan Pond is a shallow (i.e. flat bottom) hyper-saline pond. The salinity is high enough that it doesn't freeze even in winter. Therefore, unlike other lakes and ponds in the dry valleys, it has no ice cover. It has been described as a groundwater discharge zone. The dominant ions in solution are calcium and chloride. The area around Don Juan Pond is covered with sodium chloride and calcium chloride salts that have been precipitated as the water evaporated. Area and volume of Don Juan Pond varies over time. According to the USGS topo map published in 1977, the area was approximately 0.25 sq. km. However, in recent years the size of the pond has shrunk considerably. The pond has changed over the past 5 years although this is mostly anecdotal. The maximum depth in 93-94 was described as ""a foot deep."" In Jan 97, it was approximately 10cm deep; in Dec 98 the pond was almost dry everywhere except for an area 10's of sq meters. Most of the water that was left was restricted to depressions around large boulders in the pond." "Pony Lake on Ross Island",,"77-33 S","166-09 E",0.1,,0.12,0.07,,,,,"Pony Lake on Ross Island is located on Cape Royds. It is a shallow pond ~120 m long, 70 m wide, and 1-2 m deep. Huts built by Shakleton's expedition of 1908 face the southern end of the pond. The eastern shore of Pony Lake is adjacent to a penguin rookery and the pond has high nutrient concentrations. High levels of Na, Cl, and SO4 are probably due to the marine influence. The water is well mixed by strong winds that prevail at the cape."
