Progressive thickening of the crust has occurred during the latter part of Phanerozoic time in the northwestern United States. This thickening is correlated with progressive increase in elevation relative to sea level and is probably caused by in situ aggregation of sial. Intermediate stages in the process were probably similar to the intermediate crustal structures now found in some small ocean basins.
