The Exploring Expedition to the Rocky Mountains, Oregon and California

"The Exploring Expedition to the Rocky Mountains, Oregon and California" by John Charles Frémont was a travelogue and reference text of sorts that helped readers learn more about the western and Pacific Northwestern parts of the United States. Delving into the area's history as a gold rush area, the book then continues on to its landscape and all of the natural wonders this part of the country has to offer.
