Eagle Rock
Map SatelliteEagle Rock supports two small stands of the relict and rare Santa Cruz cypress, Cupressus abramsiana. Some of the trees on the private site are 20 meters (60 feet) to 25 meters (80 feet) high. (See Butano Ridge and Bonnie Doon). Members of chaparral and mixed evergreen forest communities are intermingled around and near the cypress groves, including Dendromecon rigida, Pinus attenuata and Adenostoma fasciculatum.
The trees are on Butano sandstone, formed in the Eocene. At the privately owned site are some caves which were formed by the interaction of chemical solution and pluvial action.
Integrity: There is a look-out station on the summit of Eagle Rock. The groves appear undisturbed.
Use: Research, educational, observational. Private.
