Natural Features & Ecosystems
In Sequoia and Kings Canyon National Parks, the dynamic landscape evolves from geologic processes working over millennia to sculpt granite, marble and other forms of rock. Here in the parks are canyons carved by rivers and glaciers, towering rugged peaks and miles of underground caverns. Found throughout the park are thousands of lakes and ponds and miles of rivers and streams; together they form important watersheds in the park. These watersheds are a valuable source of water not only to park resources but also to the inhabitants of California’s Central Valley.
Did You Know?
Sequoia and Kings Canyon suffer from one of the worst air-pollution problems of any national park! Pollution — particularly ozone — from the Central Valley and the Bay Area is carried up into these mountains by warm winds. It challenges all of us everywhere to clear the air!
