The "Historical Aerial Photographs of Maryland, 1937-1990, County Collection" consists of black and white aerial photos (9"x9", 1:20,000-scale) from several time periods: 1937-1938, 1949, 1951-1953, 1957, 1961-1964, 1968, 1970-1972, 1979-1981, and 1983-1990. These photographs were usually flown or otherwise acquired by the U.S. Department of Agriculture (USDA), the U.S. Geological Survey (USGS), or the private firm Air Photographics, Inc. (API). USDA and USGS photographs were donated to the Maryland Geological Survey (MGS), mainly by the Maryland State Highway Administration (SHA). MGS purchased the copyrighted API photographs. Due to copyright limitations, the public may view the paper API photographs but...

Continuous, intact vibracores, in 1-m or 5-m sections, collected between 1984-1997, on the Maryland continental shelf by MGS or the U.S. Army Corps of Engineers (USACOE) for the purpose of assessing sediment suitable for beach nourishment. Half of each core, longitudinally, is archived. Since collection, all samples have been stored indoors, but at ambient outdoor temperature and humidity. Bottom Sediment Cores, Maryland Continental Shelf Core repository started out as a good project when funded, but, as funding became scarcer, upkeep of the respository suffered. MGS has already invested $30-40,000 in this collection and has added to it. It would be a shame to allow the collection to deteriorate to the point that...

Paleontological or palynological reports and correspondence from various researchers derived from the drilling of approximately 200 Maryland wells or boreholes and 1 Virginia well. Multiple samples were analyzed from many of the wells/boreholes. Most wells are located within Maryland’s Coastal Plain. An additional 20+ folders contain paleontological or palynological reports, notes, manuscripts, letters, memos, and an MS thesis. Locations include Maryland’s Coastal Plain, Blue Ridge, and Piedmont physiographic provinces (Frederick and Montgomery Counties). Data from many, if not most, of these reports have been published in Maryland Geological Survey reports.

Geoscientific collections managed by Maryland Geological Survey are aggregated in the National Digital Catalog to enhance discovery and use of valuable samples and data for further scientific research. Contact information and material access instructions are provided for the individual collections.
Geophysical logs (gamma, density, electric, etc.) for wells drilled mainly for natural gas in Garrett and Allegany Counties, Maryland. The geophysical logs are paper strip charts of data throughout the depth of each well. All 337 logs have been scanned (.tif format). An out-of-print MGS report, Basic Data Report 5, Deep Wells of Maryland, has data from all deep wells in the State, including many of these Western Maryland wells.

This collection (known internally at Maryland Geological Survey as Component 2) consists of 505 enlargements of unrectified, black-and-white aerial photographs flown along Maryland's barrier islands during 13 different time periods (or "sets") between October 1952 and July 1964. Each of the photographs in the collection is about 2 feet x 2 feet in size. Some of the photographs have a scale of 1:14,400 or 1:6,000 stamped on the front. On the backs of many of the photographs is another stamp of "1" = 200 ft". The photographs cover the Maryland section of two narrow barrier islands that lie along Maryland's Atlantic coast, separated by the Ocean City Inlet: Fenwick Island to the north and Assateague Island to the...
