The Blue Hills of Maryland
(1st edition, 1993) Paula M. Strain, PATC trail overseer on South Mountain, conducted extensive research for this history of the lands, legends, and people along the AT in western Maryland. Her book is a readable and well-researched account of the historical happenings in the small towns, in the Antietam, Catoctin, and upper Monocacy valleys, and on the railroads, canal, trolley, and trails that served the people who lived there. With this book, everyone hiking, camping, or visiting in this area will enjoy it more for knowing the history of these rugged mountains and peaceful valleys.
