and an excerpt from
http://midforestlodge.com/history.htm
"...A logging railroad spur from Meredith along the present route of M-18 to a point six miles south of Houghton Lake, was known as the “Y”. One spur went west to Boyce Lake, another east to Headquarters Lake, and a third north to Houghton Lake, where logs were dumped from a 2000-foot staging trestle to the ice below.
The coming of the railroad in the 1870's brought many changes in lumbering methods. Prime tracts of remote timber became accessible. Private companies built grades and rails were dragged in by horses. Logs were loaded on flat cars and small locomotives pulled the flat cars to the nearest rollway. The logs were taken to Houghton Lake. The Muskegon Booming Company made the river drive downstream to the owner's mills in Muskegon. Much of this timber was used to rebuild Chicago after the Chicago fire of 1871. Men came to work in the lumber camps for $1.00 a day."
