A stern-wheel packet with wood hull (175 ft. x 35 ft. x 5 ft.), City Of Camden was built at Howard Shipyards and Dock Company (Jeffersonville , Indianna) on the Ohio River in 1893. Owned by Captain LaVerrier Cooley in New Orleans, City Of Camden operated on the lower Mississippi River between New Orleans and the Ouachita and Red Rivers. She was sold to Captain Frank Lumsden of Mobile, Alabama in 1904 and was blown onto a mud flat during a hurricane Dismantled in 1910.
(This was almost certainly the hurricane of September 1906. There was not a notable storm at Mobile in 1905. So, I am of the opinion that the main photo “On the Waterfront: 1905” which is tagged “circa 1905” is actually from late 1906 or later.)

Notice the SS Trafalgar at the bottom

Who wants to take a stab at identifying the schooner parked next to the Trafalgar?

Appears to be the wreckage of the City of Camden (built 1893), a Ouachita River steamboat, on the far shore. To get to Mobile Bay, she would have gone down the Ouachita, the Tensas and Black Rivers, the Mississippi, and then east along the Gulf Coast to Mobile.

I'm not particularly acrophobic but the two guys and cart on the sagging gangplank give me the heebie jeebies.
