**Glaciers of the Alps, 1856** This lithographic map documents the alpine glacial systems spanning Switzerland, France, and Italy, surveying the major ice fields during the height of 19th-century glaciological study. Created during the period when scientists first began systematically measuring glacial retreat, the work captures the Alps' frozen landscape with remarkable topographical precision. The lithography exhibits exceptional clarity in rendering the complex elevation changes and ice flow patterns across the tri-national alpine region.
