Most of these layers date from Oct-2007 or earlier, please see the Polar GeoSpatial Center for more updated base and specialized layers.The spatial GIS layers contained in this ZIP file were exported from the 2006 MCM-LTER Spatial Database (now deprecated) in the ESRI Shape File format. For your convenience, Layer Files (.lyr),  which are already symbolized, are also included. The spatial layers contained in the MCM-LTER Spatial Database are accurate (depending on the date the shapefiles in this ZIP file were last exported, they may be out of date).  List of layers: Camp locations.lyrglacier stake locations.lyrglaciers.lyrlakes and ponds.lyrmaximum extent.lyrmet station locations.lyrocean.lyrstream gauge locations.lyrstreams - monitored.lyrstreams - not monitored.lyrtopo 50m.lyr  2006-10-10 2007-11-01 ground condition  Most layers in this ZIP file are from the 1977 USGS Quads. These layers were originally created by Mike Prentice's team at UNH as part of the VALMAP project. In 2007, the layers were cleaned up and properly attributed by Chris Gardner (MCM-LTER Information Manager). They were then added to the MCM-LTER Spatial database, exported, symbolized and added to this ZIP file. Other layers such as glacier stake locations, met station l ocations, camp locations, etc. were created by Chris Gardner. Ancillary data and notes entered into DEIMS and standardized in 2015 by Inigo San Gil  As needed The Taylor Glacier is an Antarctic glacier about 54 kilometres (34 mi) long, flowing from the plateau of Victoria Land into the western end of Taylor Valley, north of the Kukri Hills, south of the Asgard Range. The middle part of the glacier is bounded on the south by Beacon Valley.Scott (early nineties British Antarctic expedition) named the glacier for Griffith Taylor, geologist and leader of the Western Journey Party of the British Antarctic expedition.Like other glaciers in the McMurdo Dry Valleys, Taylor Glacier is “cold-based,” meaning its bottom is frozen to the ground below.   162.280426025391 161.683044433594 -77.721229553223 -77.769035339355 Lake Hoare occupies a narrower portion of the Taylor Valley, dammed by the Canada Glacier. 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 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.

It is fed primarily by the Onyx River, which has its origin at Lake Brownworth, and ultimately at the Lower Wright Glacier located ~27 km east of the lake. The lake has no outflow.

It is isolated under year-round ice cover, and is considerably more saline than seawater. Lake Vida is one of the largest lakes in the McMurdo Dry Valley region and is a closed-basin endorheic lake. The permanent surface ice on the lake is the thickest non-glacial ice on earth, reaching a depth of at least 21 metres or 69 ft. The ice at depth is saturated with brine that is seven times as saline as seawater. The high salinity allows the brine to remain liquid at an average yearly water temperature of 13 degrees Celsius or 9 farenheit. Hydrology: Lake Vida has at least three named inflows: Victoria River, Kite Stream, and Dune Creek. Victoria River passes through the Vida Basin into Victoria Valley, Victoria Land as ephemeral glacial meltwater from the Upper Victoria Glacier, draining from Victoria Upper Lake. Geology: In the vicinity of Lake Vida, a variety of geological features are noted, the most significant being glaciers, lakes, valleys, ridges, and summits. There are approximately 25 named glaciers within a 25 kilometres radius with the nearest being Upper Victoria Glacier, Packard Glacier, Clark Glacier, and Clio Glacier.

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.
