Baja California, Mexico

Fall 2005

The Fall 2005 field trip took us to the Baja peninsula of northwestern Mexico. The trip included discussions of geothermal power, climbing dunes, tides, playas, alluvial fans, granitic dikes, batholiths, sand ripples, stramatolites, marine terraces, impact induced landslide deposits and much more...

Below are my pictures from the trip. Enjoy!

While clearly not a slide block (since no stratigraphy is preserved) this 1m long boulder of mudstone (?) clearly seemed out place mixed in with the surrounding conglomerate. Evidence for impact induced mass waisting?

The block's (above) texture and color is consistant with the mudstones of the Maastrichtian
