The Glaciers Left behind soil in Anoka county called till!
These lakes were
left by glaciers
receding through
Minnesota.
The Anoka Sand plain covers
almost all of Anoka county (The
Plain covers the till left behind by
the glaciers). This sand was left
when glacial lakes and rivers
drained at the end of the ice age.
Eskers!!
Esker—Sinuous ridge of sand and gravel
deposited in an ice-walled channel of a
glacial meltwater stream. The fluvial
sediment may be covered by 10 feet (3 m) or
more of till.
Eskers!!
You can see eskers and glacial troughs in the
north west corner of Anoka county! !
Glacial Troughs!!
Deep, broad, irregular
troughs—Locally contain
long lakes or chains of
lakes. Interpreted to reflect
valleys cut by meltwater
flowing beneath Superior
lobe ice that were partially
buried by subsequent
glacial events.
Deep,
broad,
irregular
troughs
