This village was called Waltersville until the product it shipped renamed it. Its quarries cut Woodstock quartz monzonite for the Baltimore and Ohio Railroad in the 1830s and later for the Library of Congress, the old Treasury Building and part of the inner walls of the Washington Monument. In Baltimore the same stone went into the Custom House, the courthouse and the old post office.
That was 1 of the hidden places.
