Service Description: Updated in 2022 to include additional lower 48 conterminous US states and remove Alaska from the national compilation. Downloadable version of this data is available at https://gbp-blm-egis.hub.arcgis.com/datasets/blm-natl-pfyc-potential-fossil-yield-classification-geologic-formation-map-index-2022-polygons/about.
This data contains values for the Potential Fossil Yield Classification (PFYC) for ranking the potential of a geologic unit to produce scientifically significant fossils. It will not display once the user zooms in beyond 1:577,791. Use the BLM_Natl_PFYC map service to view at all other scales. Contains polygon boundaries between mappable geologic units and polygon codes for the mappable geologic units. Also contains fields for geologic ages and sort codes for sorting the units by time. Additional fields were added to the source data including earliest geologic age, latest geologic age, PFYC justification, PFYC rank (1-5), and a coded representation for the standardized BLM coloring scheme for PFYC maps.
