The U.S. Geological Survey (USGS) awarded a $164,910.45 Cooperative Agreement under the National Cooperative Geologic Mapping Program (CFDA 15.810) to the Office of the State Geologist in Arkansas. The grant will fund a project to produce two new 1:24,000 scale geologic maps covering the Greers Ferry Dam and Concord quadrangles in north-central Arkansas. Key activities include field data collection, geologic mapping, rock sample analysis, and digitization of the maps and supporting data into a GEMS Level 3 geodatabase. The final geologic maps and associated products will be made available to federal, state, and local public institutions, private industry, and the citizens of Arkansas. No subrecipients are involved in this award, which has a project period from July 1, 2024 to June 30, 2025.

Geologic mapping of two 7.5-minute quadrangles in north-central arkansasproject period: FY2024 (july 1, 2024JUNE 30, 2025) the grant will be used to send two geologists to the field to collect data in an area definedby two 7.5-minute series topographic maps in north-central arkansas, specifically thegreers ferry DAM and concord quadrangles. This data will enable the geologists toproduce two new geologic maps at the 1:24,000 scale. Activities include collecting data in the field, using the data to draw maps and crosssections, and digitizing these drawings. Rock samples collected in the field will be usedto generate rock unit descriptions. Field data will also be used to create a joint diagram, acorrelation of map units, and a generalized stratigraphic column for each quadrangle. Amap layout containing these elements and others will be compiled based on a standardtemplate as a gems level 3 geodatabase. The final draft will be subjected to a rigorousreview and editing process by geologic staff. Deliverables include two new geologic maps in a gems level 3 geodatabase format. Beneficiaries include federal, state, and local public institutions, private industry, and thecitizens of the state of arkansas. There are no subrecipients of grant funding
