GoWaterfalling’s page on Alder Falls says this waterfall:
…is located about 20 miles north of Marquette on County Road 550. This is Canadian Shield country and the falls is typical of the falls found there. The falls is a slide about 30 feet high cascading down at a 45 degree angle. It falls into a deep, secluded and well shaded gorge. The gorge adds to the sense of wildness and isolation of the falls, even though it is only a mile from the main road.
Finding this waterfall is not trivial because Marquette does not seem big on marking their waterfalls or their rivers and creeks…
Upstream of the main falls are three more drops each around 5 feet high. The first of these is a short distance above the main falls and easy to reach from the north side of the creek. Upstream of that the creek has carved its way through an enormous rock, creating a narrow gorge. A second, not easily seen, drop is in the gorge. A third drop is beyond that.
