W. C. Phalen 1910 <p>By reference to the key map (fig. 1) it&nbsp;will be seen that the Johnstown quadrangle is in southwest-central&nbsp;Pennsylvania. It lies mostly in Cambria County&nbsp;but covers also small parts of Somerset, Westrmoreland, and&nbsp;Indiana counties. Most of it is included in the valley of Conemaugh&nbsp;River and its tributaries Little Conemaugh River and Stony Creek, at the confluence of which is Johnstown and&nbsp;its suburbs. The northern part of the area is in the valleys&nbsp;of Blacklick Creek and it South Branch, along which are&nbsp;the small but prosperous coal-mining town Nanty Glo, Twin<br />Rocks, Weber, Vintondale, and Wehrum.</p> application/pdf 10.3133/gf174 en U.S. Geological Survey Johnstown folio, Pennsylvania reports
