The Ohio State University 1983-06 Photographic History of Forest Encroachment in Several Relict Prairies of the Edge of Appalachia Preserve System , Adams County ,
Forest encroachment into several relict prairies located within the Edge of Appalachia Preserve System, Adams County, Ohio, was studied using a series of U.S.D.A. aerial photographs taken in 1938, 1950, 1965, and 1971. The corresponding photointerpretations reveal increased herbaceous cover after abandonment of cultivated field sites and illustrate the conversion of prairie and prairie glades to forest. All sites studied exhibited decreased percentage of prairie from 1938—1971. OHIOJ. SCI. 83 (3): 109-114, 1983

Neotectonic rotations in the Orava-Nowy Targ Intramontane Basin (Western Carpathians): An integrated palaeomagnetic and fractured clasts study
Abstract The objectives of this contribution are: (1) to promote the application of fractured clasts analysis in conglomerates for regional stress reconstructions and (2) to advance reconstruction of the Western Carpathians structural development. Our results show that the Neogene fill of the Orava-Nowy Targ Intramontane Basin underwent CCW rotation of about 30°. We infer that the rotation terminated after 8 Ma and was related to shift along NW-SE to NNW-SSE trending faults at the NE termination of the sinistral Mur-Žilina Fault Zone. Our results show that, fractured clasts analysis can be good tool for regional tectonic reconstructions. The tool is especially useful when other tectonic tools are scarce or absent. Results of our palaeomagnetic study and fractured clasts analysis verify and supplement each others. In the studied case, palaeomagnetic results allow to distinguish between regional stress field rotation and rotation of the Orava-Nowy Targ Basin Neogene fill, whereas, results of fractured clast analysis help to constrain the age of rotation.
