That's One Giant Beaver!
Giant beavers as big as bears (6 to 9 feet long, weighing 200-500 pounds) ranged the Mississippi River flats over 15,000 years ago. Picture here, in 1947, is Louis H. Powell, director of the Science Museum of St. Paul, comparing a giant beaver skull dug up on the Mississippi flats, near Hidden Falls park, with the skull of a large modern beaver.
In 2021, the Science Museum of Minnesota nominated a Giant Beaver specimen to be the official state fossil. You can read the campaign online. A bill was introduced in 2022.
Photos from the Minneapolis Newspaper Photograph Collection in the Hennepin County Library Digital Collections. The 1947 newspaper article which featured these photographs incorrectly stated that the fossil was dug up below the Lake Street Bridge, but Hidden Falls Park is in St. Paul.

🇺🇲 CURRENT AND PREDICTED TIMELINE FOR SALTWATER INTRUSION UP THE MISSISSIPPI AND INTO THE NEW ORLEANS WATER SUPPLY
A lack of rainfall in the Mississippi River basen has allowed denser saltwater from the Gulf of Mexico to intrude slowly up the Mississippi River over the last two months.
Current estimates put the saltwater intrusion reaching the New Orleans water supply in Algiers by October 20th, and the Carrollton water treatment plant by October 28th. Currently preparations are being made for the intrusion to last about 3 months, or until roughly late January according to top city officials citing data collected by the Army Corps of Engineers.
On Wednesday, the Biden Administration declared a Federal emergency after a formal request by Louisiana Governor John Bel Edwards.
According to New Orleans Sewage & Water Board the city's drinking water "is safe" for now.
