High Valley AVA is an American Viticultural Area (AVA) located in the eastern part of Lake County, California. True to its name, the valley is situated on high elevations ranging from 1,600 feet (490 m) to 3,000 feet (910 m), but it actually encompasses two distinct growing regions, the valley floor and the hillsides. The cool marine breezes are consistently sifting into the valley, keeping the valley cooler than the other appellations in Lake County. Red volcanic soils can be found on the hillsides while alluvial fans and benches on the valley floor provide well-drained beds for the vines. Red Bordeaux varietals and Syrah can be found planted along warmer ridges, while the cooler valley floor contains Pinot grigio, Pinot noir, Chardonnay, Riesling and Sauvignon blanc.

For other places with the same name, see Rattlesnake Island (disambiguation).Rattlesnake Island is an island located on Clear Lake in Lake County, northern California. Its land area is nominally 53 acres (210,000 square meters), but may vary significantly as lake levels rise and fall. It is 500 feet (150 meters) offshore from the north shore of the eastern arm of Clear Lake, the site of the Elem Indian Colony. There is evidence of Native American activity on the island, possibly dating back as much as 8,000 years, although little archaeological work has been conducted. This site is connected with the prehistoric Post Pattern, and has probably been used by the Southeastern Pomo throughout prehistoric times. The Elem Pomo Colony have claimed the island to be their place of origin, and a political and religious center. A history of ownership disputes dates as far back as the late nineteenth century. Due to a controversial 1949 U.S. court decision, the Elem Pomo tribe lost legal control of 80,000 acres (32,375 hectares) of its ancestral land, including the island. At present, legal title to the island is held by a Bay Area businessman, John Nady (founder of Nady Systems, Inc.) His 2003 attempt to obtain permits to construct a log cabin on the island was challenged by Elem Indian Colony members but eventually granted. John Parker, a local archaeologist, petitioned the federal government to add the island to the National Register of Historical Places. John Nady is currently developing a sustainable vacation home there with solar power and resident livestock.

Clearlake Oaks is a census-designated place (CDP) in Lake County, California, United States. It is located on the northeast of Clear Lake, 8 miles (13.8 km) northwest of the town of Clearlake, at an elevation of 1,335 feet (407 m).

Mount Konocti is a volcano in Lake County, California on the south shore of Clear Lake. At 4,305 feet (1,312 m), it is the second highest peak in the Clear Lake Volcanic Field, which consists of numerous volcanic domes and cones ranging from 10,000 to 2.1 million years old. Although it is often described as extinct, it is actually classified as High Threat Potential. Clear Lake Volcanic Field's alert level is currently classified as Normal.

Soda Bay is a census-designated place in Lake County, California. It is located on Clear Lake 7.5 miles (12 km) east-southeast of Lakeport, at an elevation of 1,398 feet (426 m). The population was 1,016 at the 2010 census. A resort at the place, called Soda Bay Springs, could by 1910 accommodate 150 guests.

Khawina is a former Pomo settlement in Lake County, California, one of a number of Pomo settlements catalogued by Stephen Powers. It was located at Sulphur Bank, at an elevation of 1362 feet (415 m).

The Clear Lake Volcanic Field is a volcanic field beside Clear Lake in California's northern Coast Ranges. The site of late-Pliocene to early Holocene activity, the volcanic field consists of lava domes, cinder cones, and maars with eruptive products varying from basalt to rhyolite. The site's threat level is ranked "High" at #33 in the top volcanic threats in the United States according to "2018 Update to the U.S. Geological Survey National Volcanic Threat Assessment". The last eruption being about 11,000 years ago. Cobb Mountain and Mount Konocti are the two highest peaks in the volcanic field, at 4,724 feet (1,440 m) and 4,285 feet (1,306 m) respectively. The field's magma chamber also powers a geothermal field called The Geysers, which hosts the largest complex of geothermal power plants in the world. These can generate approximately 2000 megawatts, enough to power two cities the size of San Francisco.The Clear Lake volcanics are thought to have been the heat source for the hot springs and hydrothermal activity that formed the mercury ores at the Sulphur Bank Mine, and the gold ore at the McLaughlin Mine.

The Sulphur Bank Mine is located near Clearlake Oaks and Clear Lake in Lake County, California. The 150-acre (0.61 km2) mine became one of the most noted mercury producers in the world.During the 150 years since the Sulphur Bank was discovered, the area has drawn geologists, inspired unique scientific theories, established constitutional case law and now attracts environmental scientists who study the impact of mercury contamination within the Cache Creek watershed of northern California and the Sacramento River-Delta Region and San Francisco Bay.
