McQuarrie and Wernicke (2005) produced a highly detailed series of reconstructions of the principal tectonic blocks of the southwestern United States from 36 Ma to Present. I have converted the shapefiles they produced to single KMZ file for viewing in Google Earth, including a set of polygons for each reconstruction age.
From their reconstructions, I have derived equivalent finite rotation parameters for each tectonic block from the reconstruction age to present. Watch for subsequent posts that utilize these parameters...
