• This body of water lies east of Port Angeles, Washington, through which ocean waters reach inland some 50 miles from the Pacific Coast to provide all-weather ports for ocean-going ships at Seattle, Tacoma and Olympia. The waterway is a complex and intricate system of channels, inlets, estuaries, and islands.

• This body of water is a shallow, productive estuary through which water draining from approximately forty percent of California, flowing in the Sacramento and other rivers from the Sierra Nevada mountains, enters the Pacific Ocean.

• The natural course of the river flows from Grand Lake, Colorado into the Gulf of California, but the heavy use of the river as an irrigation source often dries up the river before it gets to the Gulf of California

• Measured by the volume of its flow, this river in the northwest is the largest river flowing into the Pacific from North America and is the fourth-largest river in the U.S. The river's heavy flow, and its large elevation drop over a relatively short distance, give it tremendous potential for the generation of electricity.

• This river, prior to its modification by man, was known for its shifting channels, high turbidity , and periodic floods. This river, commonly referred to as the "Big Muddy," served as a travelway and thread of life for people and wildlife, alike. The floods that used to occur, often with destructive force, were viewed with awe and dismay by many white settlers.

• This river begins in north Colorado winding through Wyoming and the Nebraska Panhandle, joining with the South Platte just east of North Platte, Nebraska to form the Platte River . Red Cloud, the famous Sioux Chief, was born at this confluence of rivers in 1822.

• Considered the principal tributary of the upper Missouri, the river and its tributaries drain a wide area stretching from the Rocky Mountains in the vicinity of the Yellowstone National Park across the mountains and high plains of southern Montana and northern Wyoming. It is the longest undammed river in the lower 48 states.

• This mountain range stretches about 160 miles from the Utah-Idaho border, south through central Utah in the western United States. It is generally considered the western edge of the greater Rocky Mountains, and the eastern edge of the Great Basin region.

• These mountains are a high chain of in northeastern Utah and extreme northwestern Colorado. A sub-range of the Rocky Mountains, they are unusual for being the highest range in the contiguous United States running east to west.

• This mountain range is located in California. In a few places, it overlaps into neighboring Nevada. The range in Spanish is “Snowy Mountain Range.” It is bounded on the west by California's Central Valley, and on the east by the Great Basin.

• Pahá Sápa in Lakota, this small, isolated mountain range rises from the Great Plains in western South Dakota and extending into Wyoming. Set off from the main body of the Rocky Mountains, the region is something of a geological anomaly—accurately described as an "island of trees in a sea of grass".

• This is a mountain range of the Rocky Mountains that is located in the north-central portion of the State of Colorado extending north to southern Wyoming. Moving west along the 40th parallel north across the Great Plains of North America, it is the first mountain range encountered.

• This valley is a large, flat valley that dominates the central portion of California. It is home to many of California's most productive agricultural efforts. The valley stretches approximately 400 miles from north to south. Its northern half is referred to as the Sacramento Valley, and its southern half as the San Joaquin Valley

• This lake was a prehistoric pluvial lake that covered much of North America's Great Basin region. Most of the territory it covered was in present-day Utah, though parts of the lake extended into present-day Idaho and Nevada. Formed about 32,000 years ago, it existed until about 16,800 years ago, when a large portion of the lake was released through the Red Rock Pass in Idaho.

• These mountains stretch from Poncha Pass, Colorado, in the north to Glorieta Pass, New Mexico, in the south. There are ten peaks over 14,000' high in the range, more than two-dozen over 13,000'.

26• These mountains are a rugged range in

the Rocky Mountains in southwestern Colorado. The area is highly mineralized (the Colorado Mineral Belt) and figured in the gold and silver mining industry of early Colorado. Large scale mining is now uneconomical in the region, although independent prospectors still work claims throughout the range.

• This river runs through northern Nevada. At approximately 300 miles long, it is the longest river in the arid Great Basin. It has no outlet to the ocean, but instead empties into the Humboldt Sink. It is the largest river in the United States, in terms of discharge, that does not ultimately reach the ocean.
