Boulders beneath Niagara Falls, Canada

Frederic Edwin Church's sketch captures the geological drama beneath Niagara Falls, with white-highlighted rock formations and cascading water rendered in ink and chalk on paper. Church, a leading figure of the Hudson River School, combined scientific observation with romantic landscape vision. His rapid notational style—economical line work paired with selective white heightening—reveals an artist studying nature's monumental forces in preparation for finished paintings. The sketch demonstrates the nineteenth-century practice of fieldwork drawing, where artists documented landscape particulars to fuel ambitious studio compositions celebrating American natural sublimity.
