Brooklyn Park, Minnesota (Wikipedia) Brooklyn Park is a suburban city on the west bank of the Mississippi River, upstream from (north of) downtown Minneapolis in northern Hennepin County. It is the sixth-largest city in the U.S. state of Minnesota. The population was 86,478 at the 2020 census. The city still has undeveloped land and farms, including the historic Eidem Homestead, a 1900s working farm that is a popular tourist attraction for families and school field trips. Brooklyn Park is considered both a second- and third-tier suburb of Minneapolis, because much of the land north of 85th Avenue was developed after 2000.

Glacial erratic (Wikipedia) A glacial erratic is a glacially deposited rock differing from the type of rock native to the area in which it rests. Erratics, which take their name from the Latin word errare (“to wander”), are carried by glacial ice, often over distances of hundreds of kilometres. Erratics can range in size from pebbles to large boulders such as Big Rock (16,500 tonnes or 18,200 short tons) in Alberta.
