Rushing Waterfall Between Rocks--Temperance River

A powerful waterfall cascades over dark rocks on the Temperance River, showcasing the movement and energy of the flowing water. The contrast between the frothy water and the rugged stones creates a dynamic scene along Minnesota's north shore of Lake Superior. The Temperance River flows 39 miles between its source, Brule Lake, and its mouth. Brule Lake is unusual in that it has two outlets. The Temperance flows from its western outlet, and carries approximately half of the flow leaving the lake, while the South Brule River carries the other half from its eastern outlet. After leaving Brule Lake, the Temperance flows through a chain of smaller lakes for the upper half of its length.[t shares this feature with its neighbors, the Cross, Poplar, and Cascade rivers, which gives it a warmer water temperature and more steady flow than streams further to the south. After this, it proceeds to flow directly over the bedrock which is entirely igneous, formed during the formation of the Keweenawan Rift. Near Lake Superior, the river has dug deep potholes into the bedrock, some of which connected to form a narrow gorge and a system of waterfalls. The depth of the water where the river enters Lake Superior prevents the river from developing a sand bar at its mouth.
