 This area was once a portion of Rancho Cañada de Raymundo which was aggressively logged during the nineteenth century.After entering the estate from Cañada and Edgewood Roads, Phleger Road immediately crosses the south fork of Laguna Creek which flows north to Upper Crystal Springs Reservoir.Higher up the slope three minor tributaries flow into West Union Creek, which travels southeast to Adobe Corner in the town of Woodside where it joins Bear Gulch Creek, which in turn flows to San Francisquito Creek and ultimately, San Francisco Bay.
