Senate issue, including the astronomical and meteorological reports omitted from the House issue (and later reprints). Fremont's expeditions of 1842-44 resulted in the first reliably mapped route to the west coast. As expedition leader, Fremont achieved all he set out to do and more. After attaining his objective in Oregon in the fall of 1843 he turned his party south to the Great Basin and then -following the Truckee River- crossed the Sierra Nevada in January and February of 1844, reaching Sutter's Fort on March 6 without losing a man, though only half the party's animals reached their destination and a brass cannon was abandoned on the way. One of the folding maps in the text charts the course of the Rio de los Americanos (American RIver) from Mountain Lake (Lake Tahoe) to the Sacramento at New Helvetia. The editing of the field reports, drafting and writing of the narrative "Report" is now attributed to Fremont's wife, Jessie Benton Fremont.
