Kenedy Ranch, Texas

The Kenedy Ranch is one of the largest ranches in the world at 235,000 acres (951 sq km)!  On the southeastern portion of the ranch are cattle, windmills, mudflats, and a field of travelling dunes.  The dunes form a banner dune field, and the dunes themselves are barchans.  Particular things to note are the dune scars that appear as abruptly terminating vegetation where dunes have overtaken the small shrubs that grow in the area.  The 'S' shaped dune in the northwest shows this very well.  These dunes likely formed from a blowout, which allowed the sediments to begin migrating across the area.  Two converging longshore currents, as well as a predominant southeasterly wind "feed" sediment to the dune system and keep it moving in a NW trending direction.

My good friend Michael Hill who recently graduated from Texas A&M Kingsville has been studying and presenting research on this area for years.  It was his knowledge and experience that made this post possible.

SPECIAL BLOG: Adios, Earth

If you are reading this, I am long dead.  I came from the once-planet-now-atom-dust that was known as Earth.  From my secret moon base, I was able to capture Earth's final moments.  This outgoing blog transmission is my legacy.  To all who inhabit this universe, I send this message:

Do not under any circumstances ask a Mayan deity what he would do for a Klondike Bar!

The following shows the dates 12/20, 12/21, and 12/22 of 2012.
