The Arkansas Geological Survey (AGS) is the curator for the Norman F. Williams Well Sample Library and maintains well cuttings and core samples as a permanent record of rock strata that have been penetrated by wells drilled in Arkansas. Driller logs housed at the Survey contain the down hole information about the geology in the state. Each log gives the depth in feet along with the discription of material being drilled and the depth it accurs. The logs cover wells drilled in the early 1900’s to 1950’s and dispersed throughout the state giving statewide subsurface information.

The U.S. National Ice Core Laboratory (NICL) is a National Science Foundation (NSF) facility for storing, curating, and studying meteoric ice cores recovered from the glaciated regions of the world; mostly from Antarctica and Greenland. The NICL is funded by the NSF Division of Polar Programs and operated by the USGS; and the NICL’s science operations are managed by the University of New Hampshire. NICL provides scientists with the capability to conduct examinations and measurements on ice cores, and it preserves the integrity of these ice cores in a long-term repository for future investigations. The NICL was established in 1993 and is located at the Denver Federal Center, in Denver, Colorado. The NICL’s primary...
