A very interesting map for those of us who have spent or plan on spending considerable time in the L.A. area. This is a map of life expectancy as reported by L.A. county's own department of public health that was displayed in L.A. Weekly. The consensus seems to be that the wealthier parts of the county have much longer life expectancy whereas the poorer parts won't get to be as long in the tooth. "If you reside in the Westmont unincorporated area of south L.A., you live to be 72, but if you live in LaCanada Flintridge, you live to be nearly 88." (Coolican in LA Weekly).

San Andreas Plate Boundary GPS site vector map

This map shows velocity vectors of specific sites monitored by GPS across the western United States. The emphasis of this map is to show the plate boundary between the North American and Pacific plates, commonly referred to as the San Andreas fault, which is shown at the dramatic increase in magnitude of vectors on the western edge of the continent. The velocity presented on this map is probably relative to North American plate, which means that any vector with a magnitude on the North American plate is due to elastic deformation. I specifically chose to post this because it is interesting to see proof that our world is a very dynamic one, and is moving under our feet.
