History

Much of the land that became Skyline Ridge Preserve (and also Russian Ridge Preserve) was at one time owned by James Rolph, Jr. or "Sunny Jim," as he was known to his constituents. Rolph was one of California's most colorful politicians, serving as mayor of San Francisco from 1912 until January 1931, when he resigned to become the state's newly elected governor, a post he held until his death in 1934. After Rolph, the northern part of what became Skyline Ridge Preserve was owned by Mr. John Rickey of Rickey's Hyatt House in Palo Alto, who used it for a thousand-head hog ranch. Alpine Pond and Horseshoe Lake were constructed in the 1950s to provide water for the ranching and agriculture operations. Later the property was passed on to the Wasserman family, who used it to raise cattle and graze horses. It was the Wassermans who established the Christmas Tree farm that still exists on the Preserve today.

The District purchased the land that became Skyline Ridge Open Space Preserve in 1982.
