The Nevada portion of the Applegate-Lassen Trail leaves the Humboldt River and The California Trail at Lassen's Meadow (now Rye Patch Reservoir), and runs in a northwesternly direction through the Antelope and Kamma Ranges, Black Rock Desert, Calico Mountains, High Rock Canyon, Long Valley, and Fortynine Pass, to enter California at Surprise Valley. This entire region is composed of desert mountains, extensive desert playas, and high- desert plateau land forms. This is typical of the type of country that all emigrant trails had to traverse in the Great Basin Region, and it is a region where, due to its isolation and the lack of subsequent development, the traces of emigrant trail are best preserved. The series of hot and cold springs along this route is, of course, the reason why it was chosen as an emigrant trail. Wagon travel required that there be water and grass available to sustain the stock - and water and grass were rare commodities in this desert region.

It should be noted here that not only is this section of emigrant trail extremely well documented in journals and diaries, but that these written accounts are enhanced by the existence of an extraordinary collection of sketches and finished drawings and paintings done by J. Goldsborough Bruff during his journey along this route in 1849. These drawings are as good as photographs for establishing features and sites along the trail. This invaluable collection is primarily housed in the Manuscript Division of The Huntington Library in San Marino, California.

This Nevada section of the Applegate-Lassen Trail is the most extensive and best preserved remnant of historic emigrant trails to be found in the Far West. Long traces of the original trail are still visible, and the individual sites selected for nominatton along the trail are still largely as they were in emigrant days. The total landscape is indeed largely unchanged. This is what is unique about this region.
