The symbol "(φp)" is incorrect. "φ", standing for Pennsylvanian, should be represented by a symbol not available on Wikipedia, resembling the paragraph symbol "¶" but reversed to look like a "P". Furthermore the designation φp is not unique to the Pottsville Formation. —Preceding unsigned comment added by Jstuby (talk • contribs) 00:59, 13 October 2008 (UTC)Reply

Given that the formation occurs prominently along the entire length of the Appalachians, particularly the valley and ridge province (second sentence), and further west in the subsurface, why does the first sentence imply it is "mapped" in only three states?
