I found an ABANDONED QUARRY on Google Earth and Decided to Visit - Port Deposit, Maryland

Описание: This Quarry is also known as "Hopkin's Quarry". There is another abandoned quarry further down the river (McClanahan Quarry) but that one is on private property (I think). It looks like the town was discussing turning one of the quarries into a park with official trails and other outdoor recreational activities such as rock climbing. I wonder if that is still happening....
Comment if you have additional info (or if I got something wrong)!

"Port Deposit "Granite" is a coarse-grained, granite gneiss with an obvious foliation produced by black mica. The rock was used in early days by colonial settlers, but commercial use did not occur until about 1816 when stone was needed for the abutments to the Susquehanna River Bridge. A quarry was established at Port Deposit and by the 1830's much of the stone was being shipped to Baltimore. Other quarries were opened in Cecil County as the stone gained acceptance. Some of the buildings in which this popular stone was used: Fort Carroll, Fort McHenry, the Naval Academy in Annapolis, Haverford College in Philadelphia, and part of the old Goucher College in Baltimore." - Maryland Geological Survey
