WebGlacial Geology. The glacial geology of Minnesota is rather young relative to the bedrock deposits found throughout the state, tracing its origins back to the Quaternary Period. Background image: Finely-laminated lake sediment deposited over pebbly sand outwash sediment (not pictured) from an exposure in Kandiyohi County. Quaternary Period. Till plains are an extensive flat plain of glacial till that forms when a sheet of ice becomes detached from the main body of a glacier and melts in place, depositing the sediments it carried. Ground moraines are formed with melts out of the glacier in irregular heaps, forming rolling hills. Till plains are common in areas such as the Midwestern United States, due to multiple glaciation events that occurred i…
