Gibraltar Dam is located on the Santa Ynez River, in southeastern Santa Barbara County, California, in the United States. Forming Gibraltar Reservoir, the dam is owned by the city of Santa Barbara. Originally constructed in 1920 and expanded in 1948, the dam and reservoir are located in a remote part of the Los Padres National Forest. The main purpose of Gibraltar Dam is domestic water supply. It provides about 4,600 acre-feet (5,700,000 m3) of water to Santa Barbara each year, supplying almost 30% of the city's needs. Water diverted from the dam also powers a small hydroelectric plant. Due to having lost a massive portion of its capacity to sediment build-up, the lake can often fill and spill after a single storm, while drying up completely in some years. As of February 2019, sedimentation has reduced the reservoir's capacity to 4,314 acre-feet (5,321,000 m3), only 19% of its designed capacity.The dam is built in a part of the Santa Ynez River called the "Gibraltar Narrows" that gave its name to the Gibraltar (or Sunbird) mercury mine, which operated next to what is now Gibraltar Reservoir between the 1870s and 1990s.

La Cumbre Peak
La Cumbre Peak

La Cumbre Peak is a 3,997-foot (1,218 m) peak in the Santa Ynez Mountains north of Santa Barbara, California and located within the Los Padres National Forest. Composed of boulders and slabs of the Matilija Sandstone amid groves of pine trees, it is the highest summit in proximity to the city. Adjacent to La Cumbre is Arlington Peak (3,258 ft (993 m)) and Cathedral Peak (3,336 ft (1,017 m)). Other peaks within the Santa Ynez Range include Santa Ynez Peak, 15 miles (24 km) to the west, and Divide Peak, 15 miles (24 km) to the east. East Camino Cielo (originally known as Ridge Route) was constructed between October 1930 and June 1931 as a single lane road that extended 18 miles (29 kilometres) from San Marcos Pass to the summit of La Cumbre Peak. The intermittently curvaceous road was opened to the public, built with frequent turnouts and a set maximum speed limit of 15 mi (24 km) per hour. Today the road is frequently used by runners and cyclists for training, as the elevation gain is substantial and sustained, while there is relatively little car traffic. Construction of a fire lookout station upon the summit featuring a seasonal glass house was completed in the summer of 1923 by the US Forest Service, but may have been impacted by a fire that approached it from three sides in September of that year. In 1946, "La Cumbre Peak Lookout" was built to replace a California Region 5 Plan 4AR cabin that was mounted on a 10 ft (3.0 m) open timber tower. Utilizing an "innovative experimental design" that employed relatively high walls and sloped glass, the newer structure was considered to be expensive for its time (at a cost of $6,500) and was therefore the only model of its type to be constructed. The lookout was listed in the National Historic Lookout Register on June 19, 2010.
