- History of Maplewood (maplewoodmn.gov)
The written history of Maplewood begins about 165 years ago when European and French-Canadian settlers began farming in this area. Prior to this time, the land was inhabited by the Dakota Indians with occasional visits by French and English fur traders and explorers. The landscape was a mix of scrub oak and prairie with many wetlands and lakes.

Maplewood has its own “Ghost Town.” English Street and Frost Avenue was the center of this now vanished city. In the final years of the nineteenth century it was a very different place.
- Gabriel’s horn (Wikipedia)
A Gabriel’s horn (also called Torricelli’s trumpet) is a type of geometric figure that has infinite surface area but finite volume. The name refers to the Christian tradition where the archangel Gabriel blows the horn to announce Judgment Day. The properties of this figure were first studied by Italian physicist and mathematician Evangelista Torricelli in the 17th century.
