New Geyser, Norris

Thomas Moran's sketch captures a geothermal feature in Norris Basin, Yellowstone National Park. Working in pen and ink with selective shading, Moran documents the landscape with the precision of a naturalist observer. His notation identifies specific geological formations—dead trees, mineral deposits, steam vents—rendered through economical linework. Moran, who emigrated from England to Philadelphia as a child, became instrumental in visualizing the American West for Eastern audiences through illustrations and paintings. His field sketches like this served as studies for larger compositions, translating geological wonder into accessible visual form for a nineteenth-century public eager to understand the nation's natural resources and scenic treasures.
