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[edit]

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.[1]
