AB: The Plate Boundary Observatory (PBO) is the geodetic component of the NSF funded EarthScope Project. The final PBO GPS network will comprise 875 continuously operating GPS stations installed throughout the Western US and Alaska. There are 449 Stations planned for California with 232 of these in Northern California (NCA). This poster will present a progress report and highlights of GPS installations in NCA over the past year. At the end of the third year of the project (10/2007), PBO NCA installed 131 GPS stations. In the fourth year of the project we installed 64 stations for a total of 195 stations. This total comprises 80% of the along the active transform margin, 70% of the sites on volcanoes and calderas and 67% of the sites covering the extensional regime of the Basin and Range. Highlights from this year include completing reconnaissance and permitting of GPS networks around the volcanoes at Mount Shasta and Mount Lassen. Six of the eight GPS stations planned for Mount Shasta were built and at varying azimuths and distances from the crater. Mount Lassen has 9 GPS stations, 6 stations in the Lassen Volcanic National Park and 3 more on surrounding National Forest Service property. Data from these stations are available from the UNAVCO archive. We expect to complete the Northern California part of the PBO GPS network by the end of Sept 2008. In order to accomplish this goal, we are working to finalize reconnaissance and permitting activities for sites whose initial permits were rejected. There will likely be a handful of sites that we will have to relocate from their originally proposed locations in order to get a permitted location.
