Pennsylvania Archival PrintPennsylvania's spectacular Ridge-and-Valley topography is the result of 
differential erosion among a sequence of sedimentary layers laid down 
over a span of three hundred million years, and then bent and twisted 
over a similar period. The Susquehanna River drains the central and 
eastern Plateau country, while the western Plateau collects the upper 
reaches of the Ohio. 
About Archival Prints
For the lover of landforms, the delicacy and precision of the imagery 
is what matters. These maps are pure monochrome landform: without the 
names and built-up areas that appear on our Fine Art Print Landforms and
 Rivers maps (rivers and streams are shown, but not named). These prints
 are a revelation, inviting endless contemplation, without distraction.
For a print-lover, the unsurpassed quality and permanence of  both paper
 and inks may be their most important qualities. These special edition 
archival prints offer unequaled definition and subtlety of tone. Printed
 in 8 inks on 350g Hahnemühle 100% cotton Museum Etching paper, these 
are the gold standard.
All map 
dimensions are approximate. Archival prints are printed at Jeff Gaydash 
Studios. Please allow three weeks for delivery. Archival prints are 
non-returnable.   Please contact us (info@ravenmaps.com) for samples of 
archival print paper.
