This project established a permafrost monitoring network in this region, providing a baseline of permafrost thermal regimes for assessing future change at a total of 26 automated monitoring stations. Stations have collected year-round temperature data from the active layer and the permafrost starting from the summer of 2011. The strong correspondence between spatial variability in permafrost thermal regime and an existing ecotype map allowed for the development of a map of ‘permafrost thermal classes’ for the broader study region. Further, the annual temperature data was used to calibrate models of soil thermal regimes as a function of climate, providing estimates of both historic and future permafrost thermal regimes...
This collection (known internally at Maryland Geological Survey as Component 9) consists of 1,474 black-and-white aerial photographs (1,472 unique frames plus 2 duplicates) plus 2 index maps which serve as a finding aid for the photographs in the two sub-components of this collection -- DC Collection 1 and DC Collection 2. The photographs are 9 in. by 9 in. in size and cover Washington, DC and vicinity (including portions of Maryland and Virginia). The counties in Maryland covered by these aerial photographs are Anne Arundel, Howard, Montgomery, and Prince George's Counties. No date is printed on these photographs; however, based on features shown in the photographs, Maryland Geological Survey (MGS) estimates...
The U.S. Geological Survey's Upper Midwest Environmental Sciences Center (UMESC) collects aerial photography of the Upper Mississippi River System (UMRS) floodplain on a regular basis. These data are used to support the Center's long-term goals of understanding the UMRS and developing useful products for the Long Term Resource Monitoring Program (LTRMP). In 2000, 1:16,000-scale true color aerial photos were collected on the Mississippi River from Cairo, IL to Minneapolis, MN and the on Illinois River from its confluence with the Mississippi near Grafton, IL to Lake Michigan/Chicago, IL. The photos were collected using a 60% stereo overlap between photos in the same flight line and a 30% overlap between flight lines....

Cross section of basaltic next exposed by erosion in Grant Ridges, 6 miles northeast of Grant, view looking southwest. Valencia County, New Mexico. 1931.
Cross section of basaltic next exposed by erosion in Grant Ridges, 6 miles northeast of Grant, view looking southwest in sec. 3, T. 11 S., R. 9 W. Basalt in core is jointed in vertical columns and surrounded by a thin zone of platy jointing developed along the contact with white tuff. Bedded breccia overlies the tuff, and basaltic lava overlies the breccia on the far side of the cone. The tuff, chiefly rhyolitic, was erupted from Mount Taylor. Valencia County, New Mexico. 1931.

Eighth century monument, Stela F, ancient Maya archaeological site of Quirigua. Rio Motagua Valley, Guatemala. 1922.
Album caption: Stela F. One of the most distinctive of the stela at Quirigua. It projects 24 feet above the ground. This is the south face and the glyphs are perhaps the most beautifully carved of any among the Maya inscriptions. An unusual feature of this stela is that it has two dates - A.D. 1761 and A.D. 724 which is likely a leap year correction. While Stela F. is one of the tallest here it is not the tallest. Stela E. is the tallest. It is 35 feet long by 5 feet wide and 4 feet thick. It projects 26 feet 6 inches above ground and weights 65 tons. It is the largest piece of stone every quarried by the Maya. Guatemala. 1922. No index card. The Ruins of Quirigua, Guatemala - This Maya archeological site is...
