Site description Nunaluk Spit and Herschel Island are remote areas on the Beaufort Sea along the Yukon coast. The site encompasses about 45 km of coastline extending from the base of Nunaluk Spit at the west end, to Calton Point at the east end. Nunaluk Spit and the four islands east of the spit are long and very narrow pieces of land that lie parellel to the coast. The site also includes the open waters of Workboat Passage, which lie between Herschel Island and the coast. The site extends inland approximately 1 km (and occasionally up to 4 or 5 km) to the higher coastal plain. Low arctic tundra vegetation is typified by dwarf shrubs, sedges, and herbs. The coast is composed of sandy spits and deltaic wetlands.
