Tectonic Plate Boundaries
The outermost shell of the Earth consists of a mosaic of rigid “plates” that have been moving relative to one another for hundreds of millions of years.
Northern California LiDAR Hillshades
1-meter resolution bare earth hillshades from the Northern California
GeoEarthScope LiDAR topography dataset. By downloading this file and
opening it in Google Earth, users are able to browse hillshades with
two illumination angles (315 and 45 degrees) for faults in the northern
San Andreas fault system. The extent of the LiDAR data is shown by the
cyan colored outlines. The hillshades will load once the user has
zoomed into an area of interest.
