Clark Publication_Date: 2011 Title: Lidar-revised geologic map of the Wildcat Lake 7.5' Quadrangle Kitsap and Mason Counties, Washington Geospatial_Data_Presentation_Form: vector digital data Online_Linkage: http://pubs.usgs.gov//sim/3187 Description: Abstract:The Wildcat Lake quadrangle lies in the forearc of the Cascadia subduction zone, about 20 km east of the Cascadia accretionary complex exposed in the Olympic Mountains (Tabor and Cady, 1978), and about 100 km west of the axis of the Cascades volcanic arc. The quadrangle lies near the middle of the Puget Lowland, which typically has elevations less than 600 ft (183 m), but on Gold Mountain, in the center of the quadrangle, the elevation rises to 1761 ft (537 m). This anomalously high topography also provides a glimpse of the deeper crust beneath the Lowland. Exposed on Green and Gold Mountains are rocks related to the Coast Range basalt terrane. This terrane consists of Eocene submarine and subaerial tholeiitic basalt of the Crescent Formation which probably accreted to the continental margin in Eocene time (Snavely and others, 1968). The Coast Range basalt terrane may have originated as an oceanic plateau or by oblique marginal rifting (Babcock and others, 1992), but its subsequent emplacement history is complex (Wells and others, 1984). The Seattle basin, part of which lies to the north of Green Mountain, also began to develop in late Eocene time due to forced flexural subsidence along the Seattle fault zone (Johnson and others, 1994). Domal uplift of the accretionary complex beneath the Olympic Mountains occurred after ~18 million years ago (Brandon and others, 1998). Ice-sheet glaciation during Quaternary time reshaped the topography of the quadrangle, and approximately two-thirds of the map area is covered with Quaternary deposits related to the last glaciation. Geophysical studies and regional mapping indicate the Seattle fault lies north of Green Mountain. This fault produced a large earthquake about 1,000 years ago and may pose a significant earthquake hazard (Bucknam and others, 1992; Atwater and Moore, 1992; Karlin and Abella, 1992; Schuster and others, 1992; Jacoby and others, 1992). Post-glacial warping across the quadrangle is suggested by the elevations of Vashon retreat outwash that was graded to the large proglacial Lake Russell to the south. Purpose: This database and accompanying plot files depict the distribution of geologic materials and structures at 1:24,000 scale. The report is intended to provide geologic information for the study of materials properties, earthquake shaking, landslide potential, mineral hazards, seismic velocity, and earthquake faults. In addition, the report contains new information and interpretations about the regional geologic history and framework. However, the scale of this report does not provide sufficient detail for site development purposes. Supplemental_Information: DIGITAL COMPILATION: Interpretation of the lidar DEM began with a geomorphic interpretation following the protocol outlined by Haugerud (2009). We did no additional field work to make this map. Contacts of post-glacial deposits and most glacial deposits are interpreted from the lidar DEM. The digital compilation was done in version 9.3 of ARC/INFO. BASE MAP: In 2000 and 2001, the Puget Sound Lidar Consortium obtained 1 pulse/m2 lidar data for about 65% of the Wildcat Lake 7.5 minute quadrangle, which underlies the 6 ft (2 m) lidar-derived digital elevation model (DEM) serving as a base for this map. Tabor and Haugerud digitized drainage and road nets from the lidar DEM SPATIAL RESOLUTION: Uses of this digital geologic map 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 for a scale of 1:24,000 means that higher resolution information is not present in the dataset. Plotting at scales larger than 1:24,000 will not yield greater real detail, although it may reveal fine-scale irregularities below the intended resolution of the database. Similarly, where this database is used in combination with other data of higher resolution, the resolution of the combined output will be limited by the lower resolution of these data.

See Haugerud (2009) for discussion of lidar positional accuracy. Because the lidar base does not match exactly the 1953 1:24,000-scale topographic map of the Wildcat Lake Quadrangle, positional accuracy of contacts adapted directly from OFR 00-356 is even less.
