The water divide is the perimeter of the largest set of contiguous endorheic watersheds of North America, including six entire USGS watershed subregions.〔(【引用サイトリンク】url=http://water.usgs.gov/GIS/huc_name.html )〕 For example, the San Joaquin River subregion that drains to the Pacific is adjacent to the Great Basin's Mono-Northern Mojave subregion and central Lahontan subregion, and their triple point is on the Great Basin Divide. In addition to subregion triple points, the table below lists crossings of various boundaries, including those of states, United States physiographic regions (e.g., into/out of the smaller Great Basin section), Interstate Highways, and aqueducts. {|class="wikitable sortable" |+valign=top style="background:silver" | Great Basin Divide points, north-to-south except 1st section (north, OR-to-WY) is east-to-west !
