Open-File Reports
The Open-File Report series was added in 1979 to provide easy access to selected unpublished maps and reports.
The information in these publications should be considered preliminary and has not been edited or checked for completeness or accuracy. The maps have not undergone office or field review.
Many of the STATEMAP 1:24,000-scale geologic maps are released as Open-File Reports in the preliminary versions and later become part of the "Map" series when peer review is completed.
