One of the most important publications on the history of the exploration of the American West. 'On January 18, 1844, Fremont determined to cross the Sierra instead of turning eastward. Crossing over what is now known as Carson's Pass, he reached the San Joaquin Valley and turned north to Sutter's Fort. It was a tattered and exhausted outfit that arrived there on March 6th, 1844. Here he learned much about the conditions in California.' Later he crossed the Tehachapi Pass into the Mojave Desert. The large map is of particular importance as it charts hitherto unknown areas.
