Bearskin Lake is an oligotrophic glacial lake near the Boundary Waters Canoe Area (BWCA) in Minnesota, United States. The name Bearskin Lake is an English translation of the Ojibwe-language name Muko-waiani.[1] Bearskin Lake is a source of control sediment for US federal sediment toxicity studies. Bearskin Lake is home to Camp Menogyn, a YMCA camp only accessible by boat.[citation needed]

Sediments and scientific significance
editDue to the cleanliness of the lake and the physical attributes of its sediment, Bearskin Lake sediment is ideal for sediment toxicity testing.[2] 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]
