The Twin Peaks are two prominent hills with an elevation of about located near the geographic center of San Francisco, California. Only Mount Davidson is higher within the city. Location and climate The North and South Twin Peaks, also known as "Eureka" and "Noe" respectively, are about apart. The peaks form a divide for the summer coastal fog pushed in from the Pacific Ocean. Their west-facing slopes often get fog and strong winds, while the east-facing slopes receive more sun and warmth. Elevation at each summit is just over . Thin, sandy soil is commonplace on Twin Peaks, making them susceptible to erosion. On some rare occasions, Twin Peaks has been able to get a dusting of snow especially on February 5, 1976, when it got several inches of snow. Most recently on February 26, 2011, and February 5, 2019, Twin Peaks got a few flurries of snowflakes. History Early history Before the arrival of the Europeans, the native Ohlone people may have used Twin Peaks as a lookout or hunting ground. 18th and 19th centuries When the Spanish conquistadors and settlers arrived at the beginning of the 18th century, they called the area "Los Pechos de la Chola" or "Breasts of the Indian Maiden" and devoted the area to ranching. When San Francisco passed under American control during the 19th century, it was renamed "Twin Peaks". 21st century In 2016 the SFMTA introduced a traffic calming pilot to reduce the amount of space allocated to cars and make the summit area more inviting to a wider range of travel modes. The "figure of 8" roadway around the two peaks was reduced to a two-way road on the western side of the peaks, with the east side designated for pedestrians and bikes only. Attractions Christmas Tree Point lies some below the North Peak and offers vistas of San Francisco and San Francisco Bay. The view to the north extends no farther than Cobb Mountain () away, but looking southeast down the Santa Clara Valley on a clear day, Santa Ana Mountain is just visible away. To the north is one of the city's many reservoirs. It is owned by the San Francisco Fire Department, and supplies water to the Fire Department's independent HPFS water system for fighting fires, established after the 1906 earthquake and fire. The top of Twin Peaks is undeveloped. It is part of the Twin Peaks Natural
