GRAND MARAIS, MI (AP)-- An Upper Peninsula light house on Lake Superior has turned 140 years old.
The Au Sable Light Station celebrated the milestone by offering free tours to visitors over the weekend, marked down from the usual $3 cost. Tours usually run until the end of September, but have been extended through the second week of October this year.
The 87-foot light tower near Grand Marais was completed in August 1874. The keepers' residences were built in 1909. The lighthouse was manned for 84 years before the Coast Guard automated it.
A Pictured Rocks National Lakeshore official says visitors can enjoy a hike out to the lighthouse even when tours aren't offered. The lighthouse is about 1½ miles from Hurricane River Campground parking.
