The stream forming Verdigris Coulee runs southeasterly from Verdigris Lake through the Natural Area (PNT), which protects its confluence with the Milk River. This PNT adjoins the central portion of Writing-on-Stone Provincial Park and is located about 10 km north of the U.S.–Canadian border.

Other Information
Green Crystalline Substance found at Verdigris Lake is the origin of the name of both the lake and the coulee [1]. Verdigris is the common name for blue-green, poisonous, copper-based pigment [2].
What is a Coulee? Coulee is a term applied rather loosely to different landforms that refer to a valley or drainage zone, often an intermittently dry ravine in a plains landscape. The word coulee comes from the Canadian French coulée, from the French couler, meaning ‘to flow’ [3].
