Site description The Blow River Delta is located on the northeast Yukon Coast, where the river enters the Beaufort Sea. The site extends about 35 km in length, starting at the west with Shingle Point, and Escape Reef, a small island about 10 km offshore of the Blow River delta, through Whitefish Station, Shoalwater Bay, and finally, to Tent Island on the east. The inland eastern part of this site includes Moose Channel, which is the extreme northwestern arm of the massive Mackenzie River delta system to the east. The site extends inland from the coast up to 15 km to include areas of channels, ponds, and salt marshes. Storm tides can inundate a large part of the grass-sedge flats, hence a wide band of land is considered to be influenced by the sea. Most of the coastline that is not delta habitat consists of gravel and sand beaches.
