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.
