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.

Ozark National Scenic Riverways was created by an Act of Congress on August 24, 1964, to protect 134 miles of the Current and Jacks Fork Rivers in the Ozark Highlands of southeastern Missouri. The clean, clear waters of these two beautiful rivers provide excellent opportunities for johnboating, canoeing, swimming, fishing and tubing. The landscape is predominantly rural, with broadleaf forests and occasional open fields. The southeast Missouri Ozark Mountains are typified by narrow steep-sided hollows, numerous streams, and bluffs. Much of the area is underlain by soluble limestone and dolomite, giving rise to sinkholes, caves, and springs of a classical karst topography. There are over 300 recorded caves within the boundaries. There are 112 species of fish, 196 species of birds, and 58 species of mammals found in the park. There are also 25 species of snakes found in the park, including 4 poisonous species.
