Roadside Geology Guides|
March 9, 2014 | Geology.com Store
Since 1972 the “Roadside Geology” series has provided introductory information on the geology of states and small regions of the United States.
The books provide a combination of maps, travel logs, photos and commentary for the geology that can be seen along highways or visited at parks and public viewing areas. They are popular with geologists, teachers, students and others who are interested in the Earth.
Wall Maps of US States|

Raven Maps are beautiful examples of shaded-relief wall maps that display the elevation of a state in vibrant colors. These large maps look great in a classroom, den or office. Use one to mark the locations of your work or company.
Sea Level Rise and Sinking Land|
December 12, 2013 | USGS
“Communities and coastal habitats in the southern Chesapeake Bay region face increased flooding because, as seawater levels are rising in the bay, the land surface is also sinking. A USGS report concludes that intensive groundwater withdrawals are a major cause of the sinking land, or ‘land subsidence’, that contributes to flooding risks in the region.” Quoted from the USGS press release.

Ancient Seawater Under Chesapeake Bay?|
November 14, 2013 | USGS
“USGS scientists have determined that high-salinity groundwater found more than 1,000 meters (0.6 mi.) deep under the Chesapeake Bay is actually remnant water from the Early Cretaceous North Atlantic Sea and is probably 100-145 million years old. This is the oldest sizeable body of seawater to be identified worldwide.” Quoted from the USGS press release.
Slow Moving Groundwater Delays Water Quality Actions|
November 13, 2013 | USGS
New research by the USGS indicates it may take several decades for many water-quality management practices aimed at reducing nitrogen input to Chesapeake Bay to achieve their full benefit due to the influence of groundwater.
Partial Solar Eclipse Visible on Sunday Morning from the East Coast|
November 1, 2013 | NASA
“The final event of 2013 is the most interesting eclipse of the year. It is one of the rare hybrid or annular/total eclipses in which some sections of the path are annular while other parts are total. The duality comes about when the vertex of the Moon’s umbral shadow pierces Earth’s surface at some locations, but falls short of the planet along other sections of the path.” Quoted from the NASA website.
People as far west as Pittsburgh should be able to see the eclipse. Observing from the east coast.

Geographic Concentration of Scientists and Engineers|
September 19, 2013 | National Science Foundation
The geographic distribution of scientists and engineers in the United States is not uniform. Some states have much higher percentages of these professionals than other states. Virginia, Washington, Maryland and Colorado have higher than average numbers of these professionals. Arkansas, Kentucky, Louisiana, Mississippi, North Dakota and South Dakota have lower percentages.
Fourth LNG Export Facility Authorized|
September 15, 2013 | Reuters
The Department of Energy has authorized a fourth LNG export facility. The Dominion Resources Cove Point terminal in Maryland now has a conditional permit for LNG exports, which will most likely be produced using natural gas from the Marcellus Shale.

Tsunami on the Delaware River?|
September 4, 2013 | United States Geological Survey
“Imagine the Delaware River abruptly rising toward Philadelphia in a tsunami-like wave of water. Scientists now propose that this might not be a hypothetical scenario. A newly published paper concludes that a modest (one-foot) tsunami-like event on the East Coast was generated in the past by a large offshore earthquake. This result may have potential ramifications for emergency management professionals, government officials, businesses and the general public.” Quoted from the USGS Newsroom.
Fee Mining Sites
Geology.com and RockTumbler.com are
both GeoShops.com websites.
May 24, 2013 | RockTumbler.com
Lots of people enjoy going to fee mining sites where you can prospect inactive surface mines, mine tailings, soil, sediments or outcrops and keep any rocks, gems, minerals or fossils that you find. Examples include: Herkimer Diamond Mines where you can search for doubly-terminated quartz crystals, and Crater of Diamonds where you might be lucky enough to find a real diamond.
The Value of Restoring a Stream|
May 5, 2013 | USGS
“The U.S. Geological Survey released an analysis of the Watts Branch of the Anacostia River in Prince Georges County, Maryland that documents how restoration work on this urban tributary has had a substantial impact on the local economy, directly or indirectly accounting for 45 jobs, $2.6 million in local labor income and $3.4 million in value added to the area in 2011.” Quoted from the USGS announcement.
Homeowners Insurance and Sinkhole Damage|
March 8, 2013 | Geology.com
Did you know that most homeowners insurance policies do not cover damage from any type of subsidence? That includes collapse from sinkholes, oil production, ground water pumping and underground mining activity. Most insurance companies offering homeowners coverage exclude almost any type of geologic hazard from coverage – unless you make specific arrangements to acquire it yourself.

Geologic Map of Western Maryland|
January 17, 2013 | Maryland Geological Survey
“The “Geological Map of Garrett, Allegany and western Washington Counties in Maryland” is the first comprehensive geologic map of the region published in more than 50 years. [...] As residential, commercial and recreational development increases in the western portion of the State, and with the potential for the Marcellus Shale to serve as a natural gas resource, the updated map will provide necessary information on the geologic factors that affect and guide decisions about the wise use of the landscape and natural resources.” Quoted from the MGS press release.
