Shaded relief image: Superior Upland in the northeast, the flat Red River Valley in the northwest, Central Minnesota's irregular landscape, the Coteau des Prairies and Minnesota River in the southwest, and the southeast's dissected Driftless Area along the Mississippi River below its confluences with the Minnesota and St. Croix in East Central Minnesota
Bedrock geologic map of Minnesota which shows the location northeastern Minnesota on the small inset state map. The Rove Formation is along the eastern Minnesota-Canada border. The Rove Formation is in the Arrowhead Region of northeastern Minnesota, U.S., and extends into Ontario, Canada.
Shaded-relief image showing the Duluth Complex arcing from Duluth to Pigeon Point, interrupting and splitting the Mesabi and Gunflint Ranges. The Duluth Complex, the related Beaver Bay Complex, [1] and the associated North Shore Volcanic Group are rock formations which comprise much of the basement bedrock of the northeastern part of the U.S. state of Minnesota in central North America.
The Shakopee Formation is a geologic formation in Illinois, Indiana, Wisconsin, and Minnesota. It preserves fossils dating back to the Ordovician period . It is named after the town of Shakopee, Minnesota , where the formation can be seen in bluffs along the Minnesota River .
The geology of the State of New York is made up of ancient Precambrian crystalline basement rock, forming the Adirondack Mountains and the bedrock of much of the state. These rocks experienced numerous deformations during mountain building events and much of the region was flooded by shallow seas depositing thick sequences of sedimentary rock ...
In Erie County, all public transit was suspended Saturday and libraries were shuttered amid the ongoing lake-effect snow emergency. In addition to Shapiro's disaster declaration in the county, the ...
