The high plateau of the Allegheny Front dominates this terrain on the border of Centre Co and Clearfield Co. Small settlements like Sandy Ridge and Glass City sit along the winding path of S Centre St and Old Tyrone Pike, serving as hubs for a landscape deeply etched by cold-water drainages. The Philipsburg Reservoir is a central landmark among the ridges, collecting waters that flow through the diverse hollows of the region, such as Cabbage Hollow and Pool Hollow.
