The tour was Trip – pgs. 1-2 led by Temple University professor Dr. Natalie Flynn, who was assisted by Brownfields and PA DEP other faculty and staff from Temple. Approximately 40 people attended News Updates – pgs. 2-3 the tour – see group photo below.

Well Conference National Stakeholder Meeting – Not only is the park a treasure for city people seeking refuge in the park pg. 7 setting, it is a geological treasure as well. The geology consists of schist and gneiss of the Wissahickon Formation. According to information Your Help Needed, other PA geo societies etc. – provided during the trip, the geologic history of the Wissahickon Formation pg. 8 began around 1.1 billion years ago, when the supercontinent Rodinia broke apart to form the Iapetus Ocean, which covered the area during the Cambrian Period. The basement rock of Rodina consisted of gneiss. The Iapetus ocean closed during the Taconic Orogeny of the Ordovician Period. Sediments associated with the Iapetus Ocean are believed to have been formed into siltstones and mudstones, which were metamorphosed into the schist that we see today during two subsequent orogenic events known as the Acadian and Alleghanian orogenies. For those of us who grew up in Philadelphia – even though Allegheny is how we spell the street - Alleghanian is how we spell the orogeny. Hence, the mixture of schist and gneiss, as well as other metamorphic rocks (amphibolite and serpentinite, for example), are the result of the Contact Us: three mountain-building (or orogenic) events.

Administrator Wheeler made the announcement in Dauphin County, Pennsylvania. The grant funds are intended to aid under-served and economically disadvantaged communities in Opportunity Zones and other parts of the country in assessing and cleaning up abandoned or under-used industrial and commercial properties. Forty percent of the communities selected for funding will be receiving assistance for the first time. Dauphin County was awarded $300,000 in grant funding. Region 3 fared particularly well during this year’s competition with 24 communities receiving a grant award. Nearly half of the 2019 Region 3 grants “One of the most were awarded to communities that have not previously received EPA Brownfields assistance.

Kevin was an active member of AIPG and especially looked forward to attending the field trips offered each year at the annual conference. The Grand Canyon and Glen Canyon Dam field trips during the 2014 conference were among his favorites. Kevin also enjoyed traveling - typically planning one big trip every year. In November 2018, he made a trip to Israel and Jordan. Kevin had a goal of visiting every U.S. state capital and he was very close to achieving that goal. Kevin was born on June 12, 1971, in Harrisburg, Pennsylvania. He was the son of Roy Donald Frysinger and the late Doris J. (Fluke) Frysinger. Kevin is PA AIPG Section Newsletter June 2019 survived by his father, Roy, of Palmyra; a brother, Todd M. Frysinger, of Pittsburgh; a nephew, Quinn M.

Geological Survey Initiates New Study of Broad Top Coalfield, contributed by Clifford H. Dodge, Pennsylvania Geological Survey Since the mid-nineteenth century, the Broad Top coalfield of Bedford, Fulton, and Huntingdon Counties, south-central Pennsylvania (Figure 1), has been of considerable interest to geologists and mining companies alike, owing to its complex stratigraphy (e.g., coal correlations and discontinuities) and structure (e.g., steeply dipping beds, small-scale folding, and faulting), and because of its high- quality metallurgical- grade bituminous coal. The isolated Broad Top field is located about 25 miles east of the eastern edge of the Main Bituminous coalfield of western Pennsylvania and covers an area of about 75 square miles. Figure 1 It lies in the center of a wide, deep structural basin (Broad Top synclinorium) that is surrounded on all sides by intensely folded, steeply dipping rocks of the Ridge and Valley Physiographic Province. Within the Broad Top are many secondary anticlines and synclines that trend roughly N30oE. Dips are often as high as 35 degrees but may be much steeper in places toward the western terminus of the field where rocks are more intensely deformed. The Broad Top field has been extensively mined in the past in both underground and surface coal operations. Some surface mining still occurs today. Several years ago, the Bureau of District Mining Operations (BDMO), Pennsylvania Department of Environmental Protection (PADEP), asked the Pennsylvania Geological Survey (PAGS), Pennsylvania Department of Conservation and Natural Resources (PADCNR), to consider undertaking a comprehensive new geologic study of the Broad Top coalfield in order to provide sound science and assist the PADEP in its analysis and decision- making of future coal mine-permit and mine-reclamation activities for the region. Former mining practices had led to environmental degradation, largely as a result of acid mine drainage, and the impact of new mining or remining on water quality is difficult to determine at present, owing in large PA AIPG Section Newsletter part to the lack of information on the detailed stratigraphy, structural June 2019 geology, and mining history of the coalfield. Recognizing the value and Page 4 importance of such a study both for the PADEP and the coal industry (i.e., by providing the latter with information that aids in coal exploration, mine permitting, and mine development), the PAGS strongly endorsed the request. No modern-day, detailed geologic investigations and mapping of the Broad Top field have ever been undertaken—indeed, the Broad Top is probably the least studied bituminous coalfield in Pennsylvania. The most recent comprehensive study of the coalfield was published by the Pennsylvania Geological Survey in 1913 (Gardner, 1913), which covered the known coal stratigraphy and mining. Since that time, the coalfield has been much more extensively developed by numerous operators, rendering Gardner’s (1913) work as woefully inadequate and out of date. The growth of mining resulted in the generation of much additional geologic information about the field through the surveying and mapping of many underground and surface operations (mine maps) and by considerable exploratory drilling of coal lands.
