INDIAN MOUNDS PARK

Located in Indian Mounds Park on Mounds Boulevard at Earl Street in St. Paul

This point commands a view of one of the great water courses of North America. The stream which once filled this valley, named the River Warren, was larger than any river on the continent today.

During the past million years, Minnesota has been partly covered by glaciers at least 4 times. The short summers and long winters of the great ice ages caused an accumulation of snow and ice to a thickness of several thousand feet.

As the climate moderated and glaciation came to an end, enormous quantities of water were released to flow in rivers away from the ice field. The valley of the Mississippi visible from this point, was eroded by such a stream about 12,000 years ago. Scoured to a depth of 100 feet below the present river surface, the valley was later filled by sand and gravel as the force of the torrent subsided.

Erected by the Geological Society of Minnesota and the Department of Parks, City of St. Paul aided by a grant from the Louis W. and Maud Hill Family Foundation. 1954
