The Pit River is a major river draining from northeastern California into the state's Central Valley. The Pit, the Klamath and the Columbia are the only three rivers in the U.S. that cross the Cascade Range.

The Klamath River flows 257 miles (414 km) through Oregon and northern California in the United States, emptying into the Pacific Ocean. By average discharge, the Klamath is the second largest river in California after the Sacramento River. Its nearly 16,000-square-mile (41,000 km2) watershed stretches from the high desert of south-central Oregon to the temperate rainforest of the North Coast. Unlike most rivers, the Klamath begins in a desert region and flows through the rugged Cascade Range and Klamath Mountains before reaching the ocean; National Geographic magazine has called the Klamath "a river upside down".

Marshlands in the Upper Klamath Basin today are remnants of the vast Lake Modoc. Mount Thielsen in the background.
Semi-nomadic tribes inhabited the upper basin, a portion of which is seen here, with Mount Shasta viewed from Shasta Tribal lands.
