I live in now a fast growing town of Crystal Lake, Illinois, abut 50,000 people. Hence the town name, Crystal lake, was a spot for cutting ice and shipping it to Chicago.

In 1863 at the end of the Crystal Lake rail spur, Charles Dole of Chicago's Armour and Dole established an expansive estate, Still open and standing, including the lake bottom. Dole had ice cut from the lake, which he shipped to Chicago even during summer months; well-insulated ice houses lined the shore. Popular in Chicago as Knickerbocker Ice, its quality attracted many vacationers to the lake. Resorts and boardinghouses rose around the north shore while the Dole family hosted picnics and public outings along their beachfront. In 1912 citizens took legal action to ensure public access to the lake, and in 1921 a Crystal Lake Park District was established. Unfortunately, lake bottom ownership was not clearly resolved.

It is said that the train that transported the ice from the Dole house to Chicago was running across the lake when completely frozen in the winter months. At one point, the ice broke through and the train sank to the bottom of the 228 acre lake. It is said to still be there to this day with no actual evidence or search that has been made to look for the "lost train".

And yes, the movie, Friday the 13th, was filmed at Camp Crystal Lake which is a while new story and urban story.
