#451: Above: View to the east across Lake Osakis. Approximately 2 miles
away, the high ground in the view is the back (west facing) side of a
large elongate ridge extending to the east away from Lake Osakis. The
feature (Osakis moraine) was created by Wadena-lobe ice that excavated
sediment as ice advanced from the northeast, and then re-deposited the
sediment to form the ridge.
Below: The Osakis moraine is readily visible when viewing the Digital
Elevation model (DEM) for that part of the county. Note the location of
the Des Moines lobe outwash plain seen in parts of #426-428 (arrow indicates
direction of meltwater flow), and the northern extension of the Little
Birch Lake moraine seen in parts of #429-433. Lake Osakis is probably
an ice-block lake (large block(s) of stagnant ice buried by sediment)
located in a possible sub-glacial tunnel valley of the Wadena Lobe.
