Movie initial view: Looking south along township road, standing on a
flat outwash plain of the Des Moines lobe. The high ground to the south
is the north end of the Little Birch Lake moraine. The outwash was deposited
by a meltwater stream that flowed from southwest of the high ground.
The middle image is looking west across the flat outwash plain. Although
flat in appearance, there is a gentle downward slope from south, near
the Des Moines lobe ice margin, north to Long Prairie where it meets the
Long Prairie River channel. The image pans across the channel towards
the north. The northwest image begins with a close view of the airport
south of Long Prairie, than pulls back to show the extent and width of
the outwash plain to the north.
The final zoom shows high ground that is Wadena-lobe till, forming the
channel wall on the northeast side.
