The area of Nicollet Mall in front of the IDS Center is familiar to television viewers: the character of Mary Richards on The Mary Tyler Moore Show was seen on Nicollet Mall looking at an IDS shop in the opening montage of the show.
The [Georgia Depression] landscape features glacially striated tablelands and rolling hills underlain by sedimentary rocks.
The majority of soils in the [Georgia] depression are formed from glacial till, glacial outwash, and Lacustrine deposits.
Much of the current topography was formed through the erosion of the depression by the Cordilleran Ice Sheet during the Vashon Glaciation, which lasted from about 19,000 – 16,000 BP.
