- A thousand years ago the area around the confluence of Trout Brook and Phalen Brook near the Mississippi River was a marshy flood plain. By the early 1900s, the entire delta had been expanded by filling and became an industrial railroad corridor. As rail use decreased in the 1970s, the land was largely abandoned and buildings and tracks were removed.
- Pinwheel Galaxy (Wikipedia)
The Pinwheel Galaxy (also known as Messier 101, M101 or NGC 5457) is a face-on, unbarred, and counterclockwise spiral galaxy located 21 million light-years (6.4 megaparsecs) from Earth in the constellation Ursa Major. It was discovered by Pierre Méchain in 1781 and was communicated that year to Charles Messier, who verified its position for inclusion in the Messier Catalogue as one of its final entries.
