Abstract

The earliest research on the siliceous raw materials in the territory of Poland dates back to the first years after World War I. A patriarch of these studies was an archaeologist Stefan Krukowski (1890–1982). Together with Jan Samsonowicz (1888–1959), then a young geologist, they undertook a grand survey focused on flint deposits and prehistoric exploitation sites. The year 2022 brings a centennial celebration of their most prominent discovery: Krzemionki (Fig. 1). Exactly on July 19th, 1922, J. Samsonowicz realized that the unusual landscape of Krzemionki is a remnant of a prehistoric flint mine; he later wrote about this: “It came out that the mentioned pits are prehistoric mining shafts, filled with debris and soil” (Samsonowicz 1923: 22, translation by the Editors).
