The California Trail carried over 250,000 gold-seekers and farmers to the gold fields and rich farmlands of California during the 1840's and 1850's, the greatest mass migration in American history. Today, more than 1,000 miles of trail ruts and traces can still be seen in the vast undeveloped lands between Casper Wyoming and the West Coast, reminders of the sacrifices, struggles, and triumphs of early American travelers and settlers. More than 240 historic sites along the trail will eventually be available for public use and interpretation. The trail passes through the states of Missouri, Kansas, Nebraska, Colorado, Wyoming, Idaho, Utah, Nevada, Oregon, and California.

From the sagebrush at its alluvial base to the 13,063-foot summit of Wheeler Peak, Great Basin National Park includes streams, lakes, alpine plants, abundant wildlife, a variety of forest types including groves of ancient bristlecone pines, and numerous limestone caverns, including beautiful Lehman Caves.

Lake Mead National Recreation Area (NRA) offers a wealth of things to do and places to go year-round. Its huge lakes cater to boaters, swimmers, sunbathers, and fishermen while its desert rewards hikers, wildlife photographers, and roadside sightseers. Three of America's four desert ecosystems--the Mojave, the Great Basin, and the Sonoran Deserts--meet in Lake Mead NRA. As a result, this seemingly barren area contains a surprising variety of plants and animals, some of which may be found nowhere else in the world.
