One of the most popular places for picnic and excursions was to go to the Big Spring at Indian Lake. Initially, one crossed Indian Lake and then hiked to the Big Spring, but later, there was a narrow-gage railroad that took people from Thompson to the Big Spring.
In 1889, a Mr. Shaw of Manistique began regular trips from his yacht on Indian Lake three times a week with pickups at three different locations. Big Spring is an oval pool area that measures 300 feet by 175 feet and has a depth of 40 feet. Initially, people built rafts so they could go out into the pond.
