The Ottawa National Forest dominates this landscape in the western Upper Peninsula, where the border between Ontonagon and Houghton counties bisects a densely forested wilderness. The hydrology of the region is defined by the East Branch Ontonagon River, which winds through the southern portion of the quadrangle. Several notable water features characterize this area, including the namesake Sparrow Rapids and the drop of Onion Falls along Onion Cr.
