Water Gap, and on the hill summits southeast of Kittatinny 
Mountain at an altitude of 800 feet. This altitude is a very 
persistent one in the Appalachian Valley from this region to 
Susquehanna River. The Hamburg and Slatington quadrangles 
show the Honeybrook peneplain dominating the interstream areas. 
It retains an altitude of 800 feet in the Blue Ridge province and is 
well shown east of Reading, where Neversink Mountain, Guldin 
Hill, and the southeastern spur of Penn Mountain preserve its 
surface (see Fig. 9). The Honeybrook and the Schooley are here

In the Piedmont province the Honeybrook descends to 700 feet. 
On the divide between Susquehanna and Schuylkill rivers the 
North and South Chester Valley Hills preserve this peneplain. 
The most extended remnant of it is found on the granite about
