Begun in 1836 and lasting until 1842, the first Pennsylvania Geological Survey would not publish its results until 1858 due to budget problems and other delays. Despite these setbacks, in George Merrill's words, Rogers' final report "was an epoch-making work, and beyond question the most important document on the geology of America that had appeared up to date, with the exception of the final reports of the New York Survey." These geologic maps accompanied the final report (not included) and were the first such maps prepared for the state. They contain impressive cultural and topographical detail, including cities, towns, street grids, county names and boundaries, roads, railroads, mills, ferrys, springs (water, salt and oil!), and more. The geologic color scheme adopted by Rogers nicely accentuates the complex folded structure of the Appalachian Mountains (H. D. and W. B. Rogers were the first to work out the folded nature of the Appalachians) giving this map a very pleasing appearance. The contents of the portfolio include:

A. [On 3 Sheets] Geological Map of the State of Pennsylvania, Constructed from Original Surveys Made Between the Years 1836 and 1857..., printed color (23.1 x 36.4").

B. [On 2 Sheets] Geological and Topographical Map of the Anthracite Fields of Pennsylvania, Constructed from Original Explorations and Instrumental Surveys..., printed color (35.2 x 26.2").
