The village of Rheems lies in the carbonate valley of northern Lancaster County, in southeastern Pennsylvania, at the edge of the Appalachian Piedmont Province (Fig. 1). Rheems is 2 mi (3.2 km) east of Elizabethtown, in the 7½-minute quadrangle bearing that town's name. The quarry is a short distance west of the village, adjacent to East Harrisburg Avenue in West Donegal Township. If you are arriving from some distance, the quarry can be most easily approached from the Rheems/Elizabethtown exit of Pennsylvania 283 (Fig. 2).

Rheems quarry is currently active; it is accessible only on weekends and after work ceases at 3:30 p.M. on weekdays. Permission to enter may be obtained by letter, phone, or in person from Union Quarries, Incorporated, Old Harrisburg Pike, Rheems, Pennsylvania 17570 (717-367-1080). Permission may also be obtained from the present superintendent, Denny Dupler, whose phone number is 367-4515. The quarry maybe entered by foot or by car.
