West Bearskin Lake is an oligotrophic glacial lake near the Boundary Waters Canoe Area (BWCA) in Minnesota, United States. West Bearskin Lake is a source of control sediment for US federal sediment toxicity studies. West Bearskin Lake is also home to Camp Menogyn, a YMCA camp only accessible by boat.

Sediments and Scientific Significance

Due to the cleanliness of this pristine lake and physical attributes of the sediment, West Bearskin Lake sediment is ideal for sediment toxicity testing.[1] West Bearskin Lake sediment is used as a control sediment in the federal government's toxicity tests and was used to develop the US EPA's toxicity testing methods.[2]
