New York Times: "Dead Horse Bay sits at the western edge of a marshland once dotted by more than two dozen horse-rendering plants, fish oil factories and garbage incinerators. From the 1850's until the 1930's, the carcasses of dead horses and other animals from New York City streets were used to manufacture glue, fertilizer and other products at the site. The chopped-up, boiled bones were later dumped into the water. The squalid bay, then accessible only by boat, was reviled for the putrid fumes that hung overhead."
By the end of the 19th century the site became a landfill that was filled by 1930, capped, and then blew open in the 1950's and has been spewing its antique garbage into the bay since.
My favorite find of the day, a rusty child's roller skate.
Bottles for everything. From what I can tell, the ones I found were mostly used for perfume, booze, and pharmaceuticals.
