GUIDEBOOK ARCHIVE

A complete collection of guidebooks can be found below.

1973

Structure and Silurian-Devonian Stratigraphy of the Valley and Ridge Province, Central Pennsylvania

Leaders:

R. T. Faill, R. W. Wells, R. P. Nickelsen, D. M. Hoskins
Guidebook
No Road Log
The Valley and Ridge Province of the Appalachians has been considered a classic area of relatively simple geologic structures with complete and undeformed Paleozoic stratigraphic sections. Revisions of the structural geology and stratigraphy are demonstrated in this field trip guide.

1972

Stratigraphy, Sedimentology, and Structure of Silurian and Devonian Rocks Along the Allegheny Front in Bedford County, Pennsylvania, Allegheny County, Maryland, and Mineral and Grant Counties, West Virginia

Leaders:

J. M. Dennison, W. deWitt, K. O. Hasson, D. M. Hoskins, J. W. Head
Guidebook
No Road Log
This guidebook brings together the varied structural and stratigraphic research concerned with the Allegheny Front. It traces the geology from Pennsylvania southward across Maryland to West Virginia demonstrating the regional continuity of certain stratigraphic and structural trends.

1971

Upper Devonian Sedimentation in Susquehanna County and Hydrology, Glacial Geology and Environmental Geology of the Wyoming-Lackawanna Valley

Leaders:

S. A. Krajewski, E. G. Williams, J. R. Hollowell
Guidebook
No Road Log
The first trip presents a discussion of the geology, composition, texture, and physical properties of the flagstones of northeastern Pennsylvania and of the properties of flagstone that affect their discovery, development, and use. The second shows environmental problems resulting from the removal of the coal in the northern anthracite field and examines exposures of Pleistocene deposits.

1970

New Interpretations of Eastern Piedmont Geology of Maryland. Thirty-fifth Annual Field Conference of Pennsylvania Geologists

Leaders:

W. P. Crowley, M. W. Higgins, T. Bastian, S. Olsen
Guidebook
No Road Log
The area visited by this field conference is the northeastern Piedmont of Maryland mainly Baltimore, Cecil, and Harford Counties. The trip does not extend into Pennsylvania.

1969

The Pocono Formation in Northeastern Pennsylvania

Leaders:

W. D. Sevon
Guidebook
No Road Log
A detailed description of the Mississippian Pocono Formation is given. The trip, 240 miles long with nine stops, begins and ends in Hazleton

1968

The Geology of Mineral Deposits in South-Central Pennsylvania

Leaders:

E. Cloos, J. Freedman, G. Hole, K. Hoover, J. Hosterman, A.-Nelson, S. Sims, and D. Wise
Guidebook
No Road Log
The guide for a two day field trip begins and ends in Harrisburg. It contains detailed discussions of mineral deposits of the region. Each deposit is discussed separately. Stops were made at the GAF greenstone quarry, Hanover quarry, Thomasville stone quarry, Bender’s quarry, Mt. Holly white clay deposits, Millard quarry, and Eschelmann’s quarry.

1967

Geology in the Region of the Delaware to Lehigh Water Gaps

Leaders:

J. B. Epstein and A. G. Epstein
Guidebook
No Road Log
​ The interrelationship of the stratigraphy, structure, geomorphology, glacial geology, and economic geology of the Middle Ordovician through part of the Middle Devonian strata and overlying surficial deposits in the area between the Delaware and Lehigh Rivers in eastern Pennsylvania is demonstrated by this guide. A two day field trip log is included

1966

Comparative Tectonics and Stratigraphy of the Cumberland and Lebanon Valleys

Leaders:

D. B. MacLachlan and S. I. Root
Guidebook
No Road Log
The Cumberland and Lebanon Valley stratigraphic sequences are examined at various locations. The structural and stratigraphic discontinuities between them is demonstrated.

1965

Stratigraphy of the Pennsylvanian and Permian Rocks of Washington, Mercer, and Lawrence Counties, Pennsylvania

Leaders:

B. H. Kent, J. B. Roen, S. P. Schweinfurth, and L. D. Carswell
Guidebook
No Road Log
The guide includes two field trips: 1. Stratigraphy of Upper Pennsylvanian and Lower Permian rocks, Washington County. 2. Stratigraphy of the Pottsville and Allegheny groups of Mercer and Lawrence Counties.

1964

Cyclic Sedimentation in the Carboniferous of Western Pennsylvania

Leaders:

E. G. Williams, J. C. Ferm, A. L. Guber, R. E. Bergenback
Guidebook
No Road Log
This field trip is concerned with the existence, character, and genesis of cyclothems in the Carboniferous rocks of western Pennsylvania. It provides conceptional and physical frameworks within which some important aspects of Carboniferous sedimentation and stratigraphy can be observed
