Peter Skene Ogden led a party of Hudson's Bay Company trapping through Central Oregon in 1826, becoming the first Euro-Americans explorers to visit the area. In 1843, Captain John C. Fremont and his Army survey team explored and mapped the western part of Central Oregon. Fremont was charged with mapping the Oregon Territory east of the Cascade Mountains from The Dalles on Columbia River to Sutter's Fort in Sacramento, California. The Fremont party, including Kit Carson and Thomas Fitzpatrick, camped near Bend on 4 December 1843.
