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.

Photographs of core from 56 boreholes in Earth MRI focus areas in Wisconsin hosted on the WGNHS data viewer. Focus areas represented are: Midcontinent Rift mafic-ultramafic satellite intrusions, Paleoproterozoic weathering beneath mature quartzites, Upper Mississippi Valley Mineral District, Wolf River Batholith, and Upper Ordovician Phosphates.Focus areas are south of ceded territories except for the Midcontinent Rift mafic-ultramafic satellite intrusions, also know as the Round Lake exploration, as this is the only known site of exploration for a critical mineral, vanadium, in Wisconsin. Borehole data for these 56 drillholes has also been created. The core represented in the photographs is a subset of the collection,...

The Mineral Development Atlas (MDA) was a joint project by the United State Geological Survey (USGS), the United States Bureau of Mines (USBM), and the state surveys of Wisconsin, Illinois, and Iowa, and was launched in 1945 to gather information about mining and exploration in the lead-zinc district. The Atlas consists of section maps at 1:2400 scale showing exploration and mining activity in the lead-zinc district of the Upper Mississippi Valley. When the USGS offices in Platteville, WI closed, the Atlas was distributed to the states. The Wisconsin portion covers primarily Grant, Iowa, and Lafayette Counties, and WGNHS is currently working towards making the Wisconsin portion of the Atlas publicly available online....

Hand specimens of rocks collected in and around Marathon County as part of a bedrock mapping project in the 1970s and 1980s. Specimens were collected by P.E. Myers and UW-Oshkosh geologist Gene LaBerge as part of the field work supporting WGNHS publication Information Circular 45: Precambrian Geology of Marathon County, 1983. The collection consists of about 1500 specimens taken from approximately 580 outcrop locations.
