Lake Lagunitas

Bon Tempe Lake is a reservoir in Marin County, California, managed by the Marin Municipal Water District. It is the widest lake in the Mount Tamalpais watershed, and on Lagunitas Creek. Beneath its dam is Alpine Lake. Lake Lagunitas is immediately to its east. Built in 1948, with the construction of the earthen Bon Tempe Dam, the lake's name is an Americanization of the Bautunpi family name. The Bautunpi brothers ran a ranch and dairy that was removed with the creation of Bon Tempe and Alpine reservoirs.Fishing and hiking are activities around the lake. Rainbow trout and both largemouth and smallmouth bass are caught in the lake. The California Office of Environmental Health Hazard Assessment released a warning regarding eating fish caught from this lake based on the elevated mercury level.

The Marin Hills are a series of steep high ridges and peaks in southern Marin County. They are a part of the long Pacific Coast Ranges mountain system. The centerpoint of these hills is the 2,571 foot (784 m) Mount Tamalpais near Mill Valley. The hills are bordered to the north by the Santa Rosa Plain and Laguna de Santa Rosa; to the east by San Pablo Bay, the northern arm of San Francisco Bay; to the south by Golden Gate Strait; and to the west by the San Andreas Fault, running through Tomales Bay, Olema Valley, Bolinas Lagoon, and Stinson Beach. Parts of the hills are protected for their scenic beauty by Mount Tamalpais State Park and the Golden Gate National Recreation Area. The many ridges and peaks of these hills form a dramatic backdrop to the Golden Gate Bridge, the San Francisco skyline, and several towns around Richardson Bay when viewed from the south.

Mount Tamalpais (locally referred to as Mt. Tam) and the surrounding areas in Marin County, California are recognized as the birthplace of the modern mountain biking industry. Other Northern California hill-adjacent suburban areas had small cohorts.

Eddie's House was a doghouse designed by Frank Lloyd Wright for the Berger family of San Anselmo, California, to be used by their dog Eddie. Wright designed Eddie's House to be in keeping with the family's home, known as the Robert Berger House, which he had previously designed. The plans for the doghouse were completed by Wright in 1957, and the 4 sq ft (0.37 m2) triangular house was built in 1963. In 1973 Eddie's House was removed and thrown away, but in 2010 Jim and Eric Berger, sons of Robert Berger, rebuilt Eddie's House from the original plans for a segment in Romanza, a documentary film by Michael Miner about Frank Lloyd Wright's architectural works in California. The doghouse remains the smallest structure Frank Lloyd Wright ever designed.
