Above: Digital Elevation Model showing the topographic relief in the area of Long Prairie.


Below: View to the southwest across Charlotte Lake from the picnic area at the Long Prairie city park. The flat area including the lake, to the break in slope in the middle distance, is part of a glacial outwash plain deposited by Des Moines-lobe ice. This is part of the same outwash plain viewed in other pictures further south (#427 and #428). The ridge beyond is composed of Wadena-lobe till and forms the west side of the channel. Charlotte Lake was formed after a piece of stagnant ice that was buried in the channel melted to form a depression in the land surface.
