Regional Characteristics. The Central Valley, also known as the Great Valley of California, covers about 20,000 square miles and is one of the more notable structural depressions in the world. Occupying a central position in California, it is bounded by the Cascade Range to the north, the Sierra Nevada to the east, the Tehachapi Mountains to the south, and the Coast Ranges and San Francisco Bay to the west.
Western Branch of the Rift Valley. The western branch of the Rift Valley, known as the Western Rift Valley, runs in a great arc through the Great Lakes region, passing along lakes Albert (also known as Lake Albert Nyanza), Edward, Kivu, Tanganyika, Rukwa and to Lake Nyasa in Malawi. Most of these lakes are deep, some with bottoms below sea level.
