Did you know that California\u2019s Clear Lake is 480,000 years old, making it one of the oldest lakes<\/a> on the continent? <\/p>\n

This massive prehistoric lake lies just a few hours from San Francisco<\/a>, but most of those who drive by have no idea about its remarkable history. <\/p>\n

Here\u2019s a closer look\u2026<\/p>\n

California\u2019s prehistoric lakes<\/p>\n

While the Great Lakes may be the country\u2019s most famous bodies of freshwater, they\u2019re \u201conly\u201d 10,000-15,000 years old, having formed at the end of the last Ice Age. <\/p>\n

By comparison, California\u2019s Clear Lake is 480,000 years old, with a basin holding earlier lakes for an estimated 2.5 million years. It\u2019s also the largest natural freshwater lake entirely within California, with an impressive 68 miles of surface area.<\/p>\n

Clear Lake was long thought to be the oldest lake in North America, but paleolimnologic research<\/a> has since redesignated that title to Lake Tahoe, whose uninterrupted history dates back 2.3 million years. In fact, Tahoe is the third-oldest lake in the world behind Lake Baikal in Russia and Lake Tanganyika in Africa.<\/p>\n

California\u2019s Mono Lake also dates back 760,000 years, although its sediment record was broken due to volcanic activity.<\/p>\n

Visiting Clearlake, California<\/p>\n

Clear Lake is found in the aptly-named city of Clearlake, California, which is known for its perennial sunshine<\/a>.<\/p>\n

The lake itself is divided into three arms: Upper, Oaks, and Lower. All of them offer a great range of recreational activities, from camping<\/a> in the state park to swimming and watersports. <\/p>\n

For anglers, Clearlake is sometimes called the \u201cBass Capital of the West,\u201d offering a great population of largemouth bass. <\/p>\n

You can reach Clearlake from San Francisco in less than 3 hours by car via US-101 and CA-29 N. <\/p>\n","protected":false},"excerpt":{"rendered":"Eden Vieira \/ Shutterstock \u00a0\u2013\u00a0 Senior Staff Writer \u00a0\u00b7\u00a0 March 2, 2026 Did you know that California\u2019s Clear…\n","protected":false},"author":2,"featured_media":201814,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[30],"tags":[101,103,102,104,106,105],"class_list":{"0":"post-201813","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-san-francisco","8":"tag-san-francisco","9":"tag-san-francisco-headlines","10":"tag-san-francisco-news","11":"tag-sf","12":"tag-sf-headlines","13":"tag-sf-news"},"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/posts\/201813","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/comments?post=201813"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/posts\/201813\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/media\/201814"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/media?parent=201813"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/categories?post=201813"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/tags?post=201813"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
