One of the blogs I enjoy reading is ThumbWind, a blog about (you guessed it) Michigan’s Thumb. In A Ghost Town in the Thumb they tell the story of the town of Port Crescent that was within what is now Port Crescent State Park:
Walter Hume established a trading post and hotel near the mouth of the Pinnebog River in 1844. From these humble beginnings the area took the name of Pinnebog, taking its name from the river of which it was located. However, a post office established some five miles upstream also took its name from the river. To avoid confusion the town changed its name to Port Crescent for the crescent-shaped harbor along which it was built.
Port Crescent had two steam-powered sawmills, two salt plants, a cooperage whichPort Cresent manufactured barrels for shipping fish and salt, a gristmill, a wagon factory, a boot and shoe factory, a pump factory, a brewery, several stores, two hotels, two blacksmith shops, a post office, a depot and telegraph office, and a roller rink. Pinnebog employed hundreds of area residents. Others worked at blockhouses where they extracted brine from evaporated water to produce salt. At one time a this 17 block village boasted of a population of more than 500.
