From its southern point, Cacapon Mountain rises from the landscape north of Bloomery in northeastern Hampshire County. The mountain's western flank forms a series of steep hollows such as Horsebone Hollow and the hollow that bears Falling Spring Run. Beyond these hollows lies the Cacapon River which parallels the Cacapon Mountain until it joins the Potomac River. Between Bloomery and the Morgan County line, Cacapon Mountain forms the border between Hampshire and Frederick County in Virginia. While in Morgan County, the majority of Cacapon Mountain lies in Cacapon Resort State Park. The mountain forms a series of warm springs that flow from the DevonianOriskany (Ridgeley)sandstone along the eastern flank of its anticline such as those at Berkeley Springs. Cacapon Mountain's northern end is located at the scenic Panorama Overlook off West Virginia Route 9 that overlooks three states and the confluence of the Cacapon and Potomac Rivers.
