Newton Horace Winchell

Among the many investigations that Winchell published during the forty-five years of his active work as a scientist, author, and editor, the most widely influential was his study and estimates of the rate of recession of the St. Anthony Falls, cutting the Mississippi river gorge from Fort Snelling to the present site of the falls in Minneapolis.

[2] When he accompanied the Custer expedition to the Black Hills of South Dakota in 1874, Winchell prepared the first geological map of that area.

Winchell made three trips to Kensington, examining the discovery site and the similar glacier-carried boulders in the area, and interviewing Olaf Öhman (the finder of the stone), his neighbors, and the townspeople.

Winchell married Charlotte Sophia Imus and had six children: Horace Vaughn (who also became a geologist), Ima Caroline, Avis (Mrs. Ulysses Sherman Grant), Alexander Newton, and Louise.

The trail runs about 2.5 miles along the west bank of the Mississippi River from Franklin Avenue South to East 44th Street.
