Friedrich Egloffstein’s “Grand Cañon” Drawings: An Interactive Map

Harper’s Magazine created an interactive map based on hand-drawn maps by Friedrich von Egloffstein, a forgotten cartographer and landscape artist of the American West. The first map shows the Ives expedition of 1857–8; the other reconstructs portions of the Gunnison-Beckwith expedition of 1853–4.
