Modern day Los Angeles California was built
 over the La Brea Tar Pits that dates back to
 the Pleistocene epoch of geological history.
 It is here that the bones of many prehistoric
 creatures were preserved for millenia. These
 tar deposits are underground but very near the
 surface. Normally they would be in a solidified
 state and would be inert and pose no problem
 to residents in the area. Apparently something
 has changed underground liquifying the tar and
 sending it oozing to the surface. The only thing
 that could do this a powerful heat source from
 deep underground. My theory is that magma
 is rising near the water table and superheating
 steam which is melting the tar deposits and
 creating an oozing mess on the surface. This
 is very alarming since it is an indicator of
 geological instability and could activate major
 faults causing earthquakes and landslides in
 Southern California.
