Last Document Surrendered Chicago, 5/11/1869: "Lost"
"The scow schooner Mount Vernon
stranded on a reef well offshore Kewaunee, after loading 2,800 ties at Dean's Pier at Kewaunee. The Mount Vernon
arrived at Kewaunee on the morning of the 9th of April, 1869. She loaded all the ties that were on Dean's Pier, and that evening, after the wind sprang up from the northeast, the captain "attempted to get away". The Mount Vernon
did not obey her helm, however, and went aground on a shoal offshore. The schooner ended up "broadside on and well out from shore...200 feet north of the pier and 150 feet inside, sunk even with her deck."
"On 4/23/1869, the Milwaukee Sentinel reported the Mount Vernon
as abandoned and going to pieces."
