![]() William F. Foshag working in the lab, looking through a microscope |
This collection consists mostly of materials documenting Foshag's research
on Paricutin Volcano. Included are field notes recorded by Foshag, as well as
notes and observations made by Jenaro Gonzalez and Celedonia Gutierrez;
photographs, color slides, and glass plate negatives documenting the birth and
subsequent activity of the volcano; research notes mostly concerning the
analysis of lava and other materials erupted from Paricutin; manuscripts,
reports, reprints, and publications concerning Paricutin and volcanology; and
maps of Mexico, particularly the Paricutin region. Also included in the
collection is general correspondence of Foshag, 1923, 1942-1956, including
letters concerning his study of Paricutin Volcano, his survey of Central
American jade objects, and photographs taken on several of Foshag's mineral
collecting trips to Mexico, 1926-1934. Foshag transferred a collection
of 151 photographic prints and corresponding negatives from his study of
Paricutin Volcano to the National Archives in 1951 (NARS Accession Inventory
No. 451-111). This series consists of incoming and outgoing correspondence of William F. Foshag, primarily during the years he served as head curator of the Department of Geology, USNM. The correspondence concerns the identification and analysis of gems and minerals; Foshag's study of the Paricutin Volcano; his survey of Guatemalan jade objects; scientific societies and conferences; and the preparation of manuscripts for publication. Correspondence post-dating Foshag's death in 1956 is mostly letters of sympathy written to the Department of Geology, USNM. Box 1 of 16
