The Huntley Mountain Formation is a late Devonian and early Mississippian mapped bedrock unit in Pennsylvania, in the United States.
Haystacks
The formation is composed of relatively soft grayish-red shale and olive-gray sandstone. It is located in north central Pennsylvania.[1][2][3]
The Haystacks are enigmatic mounds of sandstone that outcrop in Loyalsock Creek south of Dushore in Sullivan County. They are a single bed of quartz sandstone with an undulating upper surface with up to one meter relief. The origin of the mounds is debatable.[4]
Notable Exposures
- The type section of the formation is at Huntley Mountain in Lycoming County, Pennsylvania, on the mountainside just north of the village of Waterville.
- Base of the Loyalsock Creek gorge in Worlds End State Park
- Haystacks beds, also in Loyalsock Creek
