The hill on which the park lies is composed primarily of sand and San Francisco chert, formed in the Mesozoic era. The layout of the park uses the steepness of the hill to good advantage, offering good views of the city (particularly to the north). At the peak of the park is a small lawn. Notable views are available from various lookouts lower down, including "The Window," an overlook on the western side of the hill from which there is a sweeping vista of
Golden Gate Park, the Pacific Ocean, and, on clear days, northward up the coast to the white cliffs of
Drake's Bay. The paths along the west side are lined with gutters built by
WPA workers out of broken
headstones from the city's Victorian cemeteries at
Lone Mountain Cemetery, which were moved to
Colma in the 1930s. In a few cases the inscriptions were placed facing up and can be discerned (
Cf. the
Wave Organ). The northeast corner staircase features a large
peace symbol (the classic
Campaign for Nuclear Disarmament variety) shaped out of flower plantings. Further south a tennis court is located just inside the park at the intersection of Duboce and Buena Vista East streets. == Other points of interest ==
