Recurrent motion occurred during the mild El Niņo winter of 2004-05 (Wells and others, 2005) and again during the winter of 2005-06. This report documents the changing geometry and motion of the Scenic Drive landslide in 2005-2006. The landslide is a complex rotational and translational earth and weak rock slump with localized slow earthflow behavior (Varnes, 1978). Because we have digital mapping in successive years, we can document changes and persistent features that we interpret to reflect underlying structural control of the landslide. We have also compared the displacement history to near-real time rainfall history for the continuously recording La Honda rain gauge LAH for the period October 2004-November 2006. Purpose: This database and accompanying graphics files (2 PDFs) depict the structure, topography and history of a landslide at a 1:400 scale. The report is intended to provide geologic information for the study of landslide hazards and potential. Changes in topography over one year of motion are calculated. Estimates of the depth to the top of the landslide slip surface are determined from well logs, offset drill holes, and mass balance calculations following the method of Bishop (1999). Although the scale of this report is large, uncertainties in georeferencing and absolute elevations provide insufficient detail for site development purposes. Supplemental_Information: DIGITAL COMPILATION- Digital map data released in this report are distributed within an Environmental Systems Research Institute (ESRI) geodatabase. Data collected during the study of the landslide (see BASE MAP) and originally cast in State Plane California-III FIPS-0403 projection, NAD83 were reprojected to UTM, NAD83, zone 10 and are stored within a single feature dataset (a grouping within a geodatabase of feature classes with a common spatial reference or logical connection). Other feature classes in the geodatabase portray features along two lines of cross section through the landslide. The coordinate system of these feature classes is technically undefined, but it can be thought of as an un-referenced Cartesian system. The units represent meters and correspond, along the X axis, to real-world positions along the line of cross section (from the beginning of the line at 0 meters to the total length) and, along the Y axis, to the real-world elevations of features. Each set of feature classes has been organized into a separate feature dataset by cross section name and year for easier browsing. The map was exported from the layout view in ArcMap as an Adobe Illustrator file and added to two Adobe Illustrator files that show two versions of the map on two map sheets, several figures, and the two cross sections. Differences between the maps as they appear in the final map sheet and as they appear in the either the .mxd or .pmf files represent changes made in the Adobe Illustrator file to the symbology only and do not reflect any changes in the actual source data. BASE MAP- The topographic base map was created using a Leica differential GPS system with a local base station set up outside of the moving landslide. We used the differential GPS, a laser rangefinder, and compass and tape to monitor motion of the Scenic Drive landslide from April 2005 through November 2006. Part of the landslide was regraded to improve drainage after motion stopped in the summer of 2005. Subsequently, motion began again following heavy rains in December 2005, and we resumed measuring the slide motion. We measured displacement along the headscarp and along the northwest lateral boundary of up to 13 cm (5 in) on January 3, 2006. By January 15, displacements of about one meter (3.3 ft) were visible along the entire slide margin. Between November 6, 2005, and January 16, 2006, our survey monuments had moved as much as 2.5 m. We continued to measure the displacement of our monument array using differential GPS through the 2005-06 rainy season and after motion stopped in the summer of 2006. After the landslide stopped moving in June 2006, we mapped the landslide topography using differential GPS (measurement uncertainty of 3 cm.) Beneath heavy forest cover, we used a laser rangefinder (measurement uncertainty 0.5 m) to map critical areas of the toe and the headscarp that were inaccessible to differential GPS. Even so, there are impenetrable areas where displacement and topography are poorly resolved. Position errors in excess of 1 m (3.3 ft) may occur in forested terrain near the toe of the landslide. Although mapped in metric units, our map is contoured in feet, and subsurface data are reported in feet, consistent with drillers' logs and existing work on the landslide. Our measurements are made with respect to a local reference frame that we established, with a local vertical datum referenced to the geodetic ellipsoid. We maintained the same datum as the 2005 map (Wells and others, 2005) to more easily quantify relative changes in the landscape. Our elevations are about 108 feet below elevations referenced to mean sea level. Some areas beneath trees in the toe area and along parts of the head scarp have no GPS coverage, and in these areas, the contours do not reflect the complexity of the ground surface and its deformation. SPATIAL RESOLUTION- Uses of this digital geologic map and derivative cross section data should not violate the spatial resolution of the data. Although the digital form of the data removes the constraint imposed by the scale of a paper map, the detail and accuracy inherent in map scale are also present in the digital data. The fact that this database was edited at a scale of 1:400 means that higher resolution information is not present in the dataset. Plotting at scales larger than 1:400 will not yield greater real detail, although it may reveal fine-scale irregularities below the intended resolution of the database. See BASE MAP, above, for further discussion of uncertainties. GEOLOGY OF THE LANDSLIDE AREA- This paragraph is modified slightly from OFR2005-1191 (Wells and others, 2005). The area of activity in 1998, 2005, and 2006 occurs within an area mapped as a probable ancient landslide by Brabb and Pampeyan (1972). The landslide area is underlain by late Miocene and Pliocene Tehana Member of the Purisima Formation, a shallow marine sequence of interbedded fine sandstone and mudstone that dips gently to the southwest in the direction of the regional slope (Brabb and others, 1998). The Purisima Formation is glauconitic at its base, where it unconformably overlies more steeply dipping Oligocene and Miocene submarine pillow breccia of the Mindego Basalt (Brabb and others, 1998). These field relations are exposed just east of the La Honda fire station in a road cut on Highway 84. The head scarp of the 2005 landslide exposes a 1 m thick, nearly black organic soil horizon overlying 3-5 m of an orange-brown diamict consisting of weathered vesicular basalt clasts in a muddy matrix. Locally exposed beneath the diamict in the head scarp are outcrops of vesicular, weathered pillow basalt and pillow breccia of the Mindego Basalt. A 2 meter-high exposure of fine sandstone of the Purisima Formation crops out in a small stream about 70 m southwest of Recreation Drive. A waterfall over Mindego Basalt occurs about 200 m to the south off Recreation Drive, where it crosses a small stream. In the landslide mass, a dozen dewatering wells have been installed since 1998. They encountered landslide debris derived from both the Purisima Formation and the Mindego Basalt. On Scenic Drive the wells were drilled through disturbed, mottled, wet, brown to greenish gray fine sandstone and mudstone of the Purisima Formation containing clay seams and lenses of cobbles and boulders of basalt. Basaltic debris was more common in the wells closest to the head scarp. Drilling of the well near Recreation Drive exposed wet, disturbed, broken, and mottled fine brown and gray sandstone diamict with horizons containing sparse basalt cobbles to a depth of about 17 feet (R. Wells, field notes). Below that depth, the hole encountered largely dry, cross-laminated and burrowed, fine-grained, greenish-gray, stiff sandstone of the Purisima Formation. A trickle of water was noted at 20 feet. The hole was drilled to refusal at 37 feet (J. de Mouthe, written communication) in zeolitized basalt pillow breccia probably representing the Mindego Basalt. Well logs are shown in the cross sections. LIMITATIONS AND UNCERTAINTIES- This 2006 map represents a snapshot of an active landslide. Changes in the landslide since 2005 are shown in the report. Although individual data points are located within a few centimeters at the time of measurement, the uncertainties may exceed several meters, given the continued motion of the landslide, the lack of GPS data beneath trees in critical areas, and artifacts of the contouring method. Property lines and cultural features aside from portions of Scenic Drive have not been determined. Survey elevations are derived directly from the differential GPS and are related to the geodetic ellipsoid. Relative elevations are likely quite precise where data coverage is good, but the relation of the GPS frame of reference to local benchmarks has not been determined.
