The severe drought across Texas has had an unexpected effect for history buffs: the exposure of ghost towns, graves and artifacts that were previously underwater.

The town of Bluffton, Texas was covered by water when the Colorado River was dammed up in 1937 to create Lake Buchanan.  In previous droughts, portions of the old town have become visible, but not very often.  Now, with the worst one year drought conditions recorded in Texas history, the lake is exposing even more surprises.

And Lake Buchanan is just one example.  Other lakes around the Lone Star State have dried up, exposing  Native American artifacts, which have been subject to looting.  Lake Whitney, about 50 miles south of Fort Worth is one such site.  The lake has receded to reveal tools, fossils, and even an ancient skull.  The Army Corps of Engineers is patrolling the area to discourage more thefts.  Check out the story of Bluffton below in video:  (via cbsnews.com)
