An AUV-acoustic scan of the vessel identified as straight back steamer Choctaw collected in June, 2017. The rounded sides characteristic of this vessel can be seen via the lack of defined edge on the upper (left) side as it extends into the lake bottom. Its unique, pointed stern is also visible. Almost half of Choctaw, however, appears buried in the lake bottom. Source: Michigan Technological University/Thunder Bay National Marine Sanctuary.
