Site details

The schooner Daniel Lyons sank in October 1878 after being rammed by the schooner Kate Gillett, settling in 110 ft of water eight miles northeast of Algoma. The wreck is somewhat broken but nearly all hull structure and rigging are represented, with frequently excellent visibility (40-100 ft) that makes it a favorite of advanced divers and underwater photographers. A WHS seasonal mooring buoy marks the site.
