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.

This 76-mile reach of the Niobrara River in northcentral Nebraska was added to the nation's Wild and Scenic River System in 1991. The river is swift and shallow over much of its length, cutting through bedrock forming riffles, rapids and waterfalls. The Scenic River preserves a superb example of a Great Plains river and protects a unique ecological crossroads where six distinct ecosystems and their associated flora and fauna mix, some at or beyond their normal geographic limit. The western third of the Scenic River is home to over ninety waterfalls -- highest is Smith Falls that cascades seventy feet from a Sand Hills cliff. Many locally-owned ranches are found along the river retaining the valley's rural flavor, yet much of its wild character is preserved. Wildlife abounds: animals such as white-tailed deer, coyote, beaver, mink, bull snakes, soft-shelled turtles, turkeys, herons, and sandpipers are commonly sighted. Enjoyed by tens of thousands of canoeists yearly, the upper reach of the Niobrara is noted as one of the country's outstanding canoeing rivers. A portion flows through a federally designated wilderness.

ExploraVision is a competition for all students in grades K-12 attending a school in the U.S., Canada, U.S. Territory or a Department of Defense school. Homeschooled students are eligible to enter. It is designed to encourage students to combine their imagination with their knowledge of science and technology to explore visions of the future. Teams of students select a technology, research how it works and why it was invented, and then project how that technology may change in the future. They must then identify what breakthroughs are required for their vision to become a reality and describe the positive and negative consequences of their technology on society. Winning ideas have focused on things as simple as ballpoint pens and as complex as satellite communications. The student teams write a paper and draw a series of Web page graphics to describe their idea. Regional winners make a Web site and a prototype of their future vision.
