Site description Big Piskwanish Point is located in the southwestern corner of James Bay, about 40 km north of Moosonee. The site consists of a narrow system of gravel ridges that extend for about 5 km in each direction of the point. Inland from the ridges, a 1.5 to 2 km wide strip of seasonally flooded supertidal marsh lies between the coastline and an inland area of willow and alder scrub. Submerged shoals extend for up to 2 km offshore. This site experiences subarctic-like conditions due to the adjacent cold waters of Hudson and James Bay; the mean annual temperature is about -1°C. The tidal range at this site is about 2 m.
