For some reason this post went to May 26th when I published it this morning. Not sure what I did, but I will try not to do it again!
Every time I think I know every waterfall in Michigan, one more comes a long. Great Lakes Waterfall Adventures shares that Little Union Gorge Falls is:
Located inside an outpost campground off of South Boundary Rd. in the beautiful Porcupine Mountains State Park, the Union Gorge Falls slide shallow water over a 100 plus foot drop in a forested setting. It is a short hike to reach the start of the falls, and the trail follows the river bank for a quarter mile, intersecting several times with the Union Mine Interpretive Trail. Several sections of 10-25 feet highlight the area, thin water most of the year, most likely the best time to visit is in the spring.
…The first long drop has a small, three foot deep pool below it, adding to the calm of the area.
