Hand specimens of rocks collected as a part of field work conducted primarily by present and former WGNHS staff members. Samples date from the early 20th century to the 1990s and were collected throughout the state. Many of the samples are described in the historical field notebook collection, and relationships between the samples and the field notebooks have been established and captured in identifiers. Locations for samples were taken from field notes, maps, and accession lists. There are approximately 5,700 hand samples in this collection.

This collection consists of field notebooks created by the personnel of the Minnesota Geological Survey (MGS) and its predecessor, the Minnesota Geological and Natural History Survey (MGNHS). The notes include basic data used to compile annual reports and bulletins on geological matters. For a description of the extent of geological work performed during the eras of the MGNHS and MGS, consult George M. Schwartz, “History of the Minnesota Geological Survey,” which identifies the individual studies made by officers of the survey between 1872 and 1963. The MGS was a major source of funding for faculty research, which focused on field petrology, mineralogy and economic geology and aligned to the individual professional...
