The US National Oceanographic and Atmospheric Administration, “NOAA”, released the first 3D sonar maps and images of ss City of Rio de Janeiro, built in 1878 and lost near where San Francisco’s Golden Gate Bridge stands today to become the worst maritime disaster in San Francisco history.
Arriving from the Far East on 22 February 1901, the Pacific Mail Steamship Company ship went aground in a dense fog just steps from the shore. The ship sank almost immediately, taking with her 128 of her 210 passengers and crew including US Consul General to Hong Kong, his wife and two children.
The wreck lies covered in mud in 287 feet of water.
In 1980’s salvagers reported finding the wreck but the coordinates they provided failed to correspond with any wreck known.
This summer in Lake Michigan, diver Ross Richardson discovered a cluster of at least five shipwrecks off Skillagalee Island which he believes includes the 226 foot side-wheeler AD Patchin lost in 1850 and the 150- foot brig Julia Dean lost in 1855.
He filmed his solo dives with a GoPro camera on a pole and posted the videos on his YouTube channel, “nmiwrecks”.
