Extent of Pleistocene Lakes in the Western Great Basin

Online link https://geo-nsdi.er.usgs.gov/metadata/map-mf/2323/metadata.faq.html
Description During the Pliocene to middle Pleistocene, pluvial lakes in the western Great Basin repeatedly rose to levels much higher than those of the well-documented late Pleistocene pluvial lakes, and some presently isolated basins were connected. Sedimentologic,

Overview of attributes

This data set consists of 10 coverages:
late_pl (polygon): Late Pleistocene lake boundaries. FLAG attribute indicates 1=lake present or 0=lake not present. LAKENAME attribute lists lake names. ELEVATION attribute lists lake elevation in meters.
max_pl (polygon): Maximum extent of pre-late Pleistocene lakes. Attribute descriptions are the same as those of late_pl dataset.
add_pl (polygon): Possible additional area of pre-late Pleistocene lakes.  FLAG attribute indicates 1=lake present and 0=lake not present.
basin_bnd (line): Boundary of Lahontan basin. No user-defined attributes.
add_basin_bnd (line): Inferred increase of drainage basin area. No user-defined attributes.
flows (line): Lake overflows. FLAG attribute indicates 1=late Plestocene overflow and 2=possible pre-late Pleistocene overflow and modern sill height.
study_sites (point): Field sample sites. DEPOSIT attribute lists types as "pre-late Pleistocene" or "Pliocene."
state_bnd (line): State boundaries. No user-defined attributes.
majdrain (line): Major drainages in basin. No user-defined attributes.
shadebase.tif (TIFF): Georeferenced TIFF file of shaded-relief grid for map base. Produced from DEM grid using the ARC/INFO 'HILLSHADE' command. Georeferencing information is contained in the file shadebase.tfw.

Most late Pleistocene shoreline altitudes and lake names are from Mifflin and Wheat (1979). Lake Warner shoreline from Weide (1975), Lake Alvord shoreline and overflow from Hemphill-Haley (1987), and Lake Coyote shoreline and overflow from Lindberg and Hemphill-Haley (1988). Pre-late Pleistocene shorelines from Reheis and others (1993), Reheis and Morrison (1997), and Reheis and others (in press), except for Lake Wellington (Stewart and Dohrenwend, 1984).
