View southwest and downriver from river mile 73.6 toward Solomon Temple Member (upper slope) and Escalante Creek Member (lower cliff) of Dox Formation.
View northwest toward Steamboat Mountain from north end of Powell Plateau, capped by Kaibab Formation.
Aerial view east into Squaw Canyon, lower Grand Wash Cliffs. Redwall Limestone (lower cliff strata), Supai Group of formations (gray cliffs and slopes), Pakoon Limestone/Esplanade Sandstone (upper right skyline), and Permian strata of Upper Grand Wash Cliffs (distant skyline).
View west across river mile 210.8 area from Granite Park toward channel cut into Redwall Limestone filled with Surprise Canyon Formation.
View west toward foot bridge (photograph ES123) over Coconino Sandstone narrows of Coconino Dam site, near beginning of Little Colorado River canyon, about 9 miles west of Cameron, Arizona. Ledges of Toroweap Formation overlie Coconino Sandstone.
Aerial view north toward Triassic and Permian strata in Hells Hole, upper Whitmore Canyon (photographs CS71, CS72, CS73). Stratigraphy includes Harrisburg Member of Kaibab Formation (white and red strata at bottom of photograph), overlain by lower red member of Moenkopi Formation (lower red slope), Shnabkaib Member of Moenkopi Formation (middle white and red ledges and slope), upper red member of Moenkopi Formation (upper red slope to skyline), and Chinle Formation (white strata in upper right edge of photograph).

Overview This directory was developed to provide discovery information for anyone looking for publicly accessible repositories that house geological materials in the U.S. and Canada. In addition, this resource is intended to be a tool to facilitate a community of practice. The need for the directory was identified during planning for and follow-up from a drill core repository webinar series in Spring 2020 for public repository curators and staff in the U.S. and Canada hosted by the Minnesota Geological Survey and the Minnesota Department of Natural Resources. Additional supporting sponsors included the U.S. Geological Survey National Geological and Geophysical Data Preservation Program and the Association of American...

This database portrays the surface and shallow subsurface geology of the greater Charleston, S.C. region east of 80°30′ west and south of 33°15′ north. The region covers the entirety of Charleston County and portions of Berkeley, Colleton, Dorchester, and Georgetown Counties. Units locally exposed at the surface range in age from middle Eocene to Holocene, but most of the area is covered by Quaternary interglacial deposits. These are, from oldest to youngest, the Okefenokee, Waccamaw(?), Penholoway, Ladson, Ten Mile Hill, and Wando Formations and the Silver Bluff beds. Two cross sections (not included in the database), one running southeast from Harleyville to the coastline on James Island and the other running...
This data release includes laser ablation inductively coupled plasma mass spectrometry (LA-ICPMS) U-Pb zircon geochronology data from four samples collected from syn- and post-Columbia River Basalt Group strata. Samples were collected from within alluvial fan strata and gravel-mantled hillslopes. Sample 16MANC2-01 was collected from an excavation into rounded fluvial gravel deposits along the Manastash Ridge. The unit collected includes Cascadian derived volcanic clasts and is interpreted as an inset terrace of fluvial strata deposited on the Manastash Ridge. Sample 16MANC1-06 is a rhyodacitic boulder collected on a nearby exposure of gravel mantled hillslopes along Manastash Ridge. Sample 16MRF01 was collected...
