The Great Anoka Sand Plain!!
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.
You can see eskers and glacial troughs in the north west corner of Anoka county! !
Eskers!!
Deep, broad,
irregular troughsDeep, 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.
