Wildlife conservation -- Pennsylvania
The official publication of the Pennsylvania Wild Resource Conservation Fund. The Fund is the principle agency that supports research and protection efforts for the state's natural heritage - its unique collection of native non-game animals and wild plants. It has funded statewide surveys of many rare plants and animals, and has helped bring some species back to the state. The Fund is financed entirely by public contributions and this periodical highlights how the donations are working to help scientists better understand, protect and restore Pennsylvania's wild resources.

Lower Devonian and Silurian rocks found in wells in the Plateau Province of Western Pennsylvania and adjacent areas are depicted in a series of six cross sections. The emphasis is on stratigraphic correlation of formational and group units found in the subsurface. Two volumes: Pt. 1. Stratigraphic cross sections of lower Devonian and Silurian rocks in western Pennsylvania and adjacent areas. Pt. 2. Subsurface maps of the Silurian rocks of Western Pennsylvania and adjacent areas.

The Silurian rocks in the subsurface of the Pennsylvania part of the Appalachian Plateau province can be related to the outcropping Silurian rocks of the Valley and Ridge province and the Niagara Escarpment. In general, the boundaries and compositional character of all the Silurian rock units indicate the existence of a major basis axis during Silurian time which lay roughly parallel to the present structural trend of the Appalachians through central Pennsylvania.
