Hand specimens of rocks collected as a part of field work conducted primarily by present and former WGNHS staff members.
Entries include rock hand samples related to WGNHS research projects with adequate geographic location information. These are available in the National Digital Catalog as of September 14, 2010. Documentation supporting other individual items in this data collection is currently being developed.
Each hand sample is tied to a field notebook. Accession lists for the had samples are available, but electronic versions of these notebooks are not available. Plans to integrate these into the existing master database of WGNHS data is under development. The collection includes some material that is tied to USGS research and these items are not included in the material available on the NDC.
