Waterfalls of the Keewenaw’s page on Quartzite Falls says:
Quartzite Falls is a perfect little waterfall high above the rugged gorge on Slate River. The river drops in a sudden crescent onto a large, flat slide of slate before flowing into a deep pool surrounded by cedars. Quartzite Falls may be small, but it’s shape and scenic area makes for an amazing waterfall experience.
This waterfall is a short distance downstream of Black Slate Falls, easy walking distance from the road and about a mile from the slate quarries of Arvon. These three areas make for an excellent little adventure that is fairly accessible for all ages.

The Slate River is magnificent. I spent an entire day traversing over rough, steep terrain & wading through cold water on slippery rocks to visit places that felt like no one had ever been before. Quartzite Falls, one of the many beauties on this river, is one of the easier waterfalls to access.
