MLML-Benthic Lab-Lone Tree Slide

Lone Tree Slide- Ecological Mitigation,
Monitoring, and Restoration



As a result of the Loma Prieta earthquake in October, 1989, the Lone Tree Slide, closed Highway One between Muir Beach and Stinson Beach along the northern California coast. The road was reopened in June, 1991, after over three quarters of a million cubic meters of soil and rock were removed from the slide face. The slide material was disposed into a large fill on the west side of Highway One. The seaward edge of the fill extended over 60 meters into the ocean. As a result of the slide, three major projects were directed to the Benthic Lab group: Highway One - Lone Tree Slide Monitoring; Big Lagoon Restoration; and Bolinas Lagoon Restoration.
