Climate and Terrain

The county contains 1,805 square miles, over half of which is in public ownership in the form of national forests and various parks and recreation areas. In 1996, this equated to approximately 4.5 acres of public open space for each county resident. In addition, there are a variety of privately owned timberlands, parks, campgrounds and recreational facilities that add to the feeling of freedom and open space for which the county is known. Elevations range from 200 feet at the western border in the Central Valley of California to 10,881 feet at the highest peak in the majestic Sierra Nevada Mountains. Climate varies with the elevation – from warm, dry summers and mild winters in El Dorado Hills and Placerville to the cool summers and snowy winters that have made South Lake Tahoe a world class resort.
