This collection (known internally at Maryland Geological Survey as Component 8) consists of 211 infrared, 9 in. by 9 in. aerial photographs (211 unique frames) flown on a 7.5-minute U.S. Geological Survey (USGS) quadrangle basis. The photographs date from 1988-1989 and were flown or otherwise acquired by the USGS National Aerial Photograph Program (NAPP). The Maryland counties covered by these photographs include Allegany, Anne Arundel, Calvert, Cecil, Charles, Dorchester, Kent, Prince George’s, Queen Anne’s, Somerset, St. Mary’s, Talbot, Washington, and Worcester Counties. The scale of these photographs is not printed on the photographs; however, Maryland Geological Survey (MGS) calculates the scale to be approximately...

The Historic Images Collection includes approximately 15,500 photographs, slides, lantern slides and digital media in this collection were taken during the course of geologic, mineral resource, and geologic hazard investigations carried out by Virginia Energy staff beginning in the first half of the 20th century. The collection includes images of important rock outcrops that demonstrate key features of stratigraphic units, fossils indicative of the age of rock formations, outcrop-scale geologic structures such as faults and folds, economically significant minerals and mine sites, and geologic hazards such as landslides and sinkholes. Images are available online in JPG format. High resolution imagery is available...

Static metadata (current to August 2018) of Minnesota's borehole geophysical log collection maintained by the Minnesota Geological Survey. This collection is web-accessible through the MGS Open Data Portal at https://z.umn.edu/borehole_geo, where users can obtain the most up-to-date information pertaining to old and new borehole geophysical logs and download corresponding PDF and LAS files for each log (if available). The Borehole Geophysical Database (BGD) is a collection of over 7000 borehole geophysical logs of water wells and drill holes throughout Minnesota. Database collections reside at the Minnesota Geological Survey (MGS) and are continually maintained and expanded upon by MGS staff as part of MGS mapping...

Collection includes mineral exploration cores originally obtained by the U.S. Bureau of Mines. Exploration for base metals, Mn-slate, alkaline earth elements was conducted. Cores were obtained from the following locations in Maine: Albany, Blue Hill, Brooksville, Buckfield, Hammond, Newry, Spencer Lake, TDR2, T9R3. Please contact the Maine Geological Survey to discuss access to the collection.

This collection (known internally to Maryland Geological Survey as Component 5A) consists of 103 photo-mosaic index maps (89 unique maps plus duplicates) dating from 1955-1981. The date printed on the index map (and listed in the metadata) is the date that flying (photography) was completed for each index map. Each photo-mosaic index map shows individual aerial photographs (with Flight Lines and Frame numbers) in a particular U.S. Geological Survey (USGS) 7.5-minute or 15-minute quadrangle in Maryland, Delaware, New Jersey, Virginia, or West Virginia. These index maps are black-and-white and approximately 10 in. by 12 in. in size. This collection serves as a finding aid for a portion of the Quad-Based Aerial...

Hand specimens of rocks collected as a part of field work conducted primarily by present and former WGNHS staff members. Samples date from the early 20th century to the 1990s and were collected throughout the state. Many of the samples are described in the historical field notebook collection, and relationships between the samples and the field notebooks have been established and captured in identifiers. Locations for samples were taken from field notes, maps, and accession lists. There are approximately 5,700 hand samples in this collection.

This collection (known internally at Maryland Geological Survey as Component 5) consists of 4,720 items – 4,715 black-and-white aerial photographs (4,688 unique frames plus 27 duplicates) and 5 associated index maps. The aerial photographs were flown or acquired by the U.S. Geological Survey (USGS) and organized on a 7.5-minute quadrangle basis. The photographs are black-and-white and approximately 9 in. x 9 in. in size. The scale of the aerial photography varies but ranges from approximately 1:12,000 to 1:35,400. These photographs date from 1936-1991 and were donated to the Maryland Geological Survey (MGS). The index maps serve as a finding aid for several of the flight series flown over five quadrangles...

In 2008, Virginia Department of Energy received by donation from the University of Virginia (UVA) a large collection of rock, mineral, and fossil specimens that was at risk of imminent disposal or dispersal due to the lack of adequate storage facilities. The collection includes many valuable and irreplaceable geologic specimens collected in Virginia by UVA students, faculty, and geoscientists from the early Virginia Geological Survey. Parts of the collection were at one time displayed in the Lewis Brooks Hall of Natural Science, which opened in 1877. Following the closure of the UVA Department of Geology in the 1960s, the collection was moved to various warehouse storage areas, where it was largely forgotten and...
