A couple of miles down river and around a bend we encounter the shallow waters of Pablo Rapids — a riffle, really — that caused steamboats to become grounded. Just passed the rapids is Wolf Island, named Captain Abe Wolf whose steamboat the Marion was grounded in 1866. After the crew mutinied and put Captain Wolf adrift in a small boat, they drank all the whiskey before being brought to justice. It is only another 3.5 miles to our last camp at Slaughter River. This is one of the few campsites the Lewis and Clark expedition used twice — first on May 29, 1805 on their upriver trip, and then Captain Lewis' party on their return on July 29, 1806.
