Geology on the Wing Wednesdays #10 – Sandy Creek winding through the drought-stricken Hill Country, Texas

Whew! I had a hectic holiday season, but a great one.  Too great, in fact, to be blogging.  So now I am back in the swing of things, here is a quick photo from a recent trip to see family.  Contrary to popular opinion, there is topography in Texas!  Here is a nice shot of Sandy Creek just upstream of its entry into Lake LBJ (named for the president), which is a dammed portion of the Colorado River.  As you can see, there is no flow in this creek at present, as the drought here is terrible.

Approximate lat long: 30.566596, -98.389192

According to the LCRA river report,  Lake LBJ and the other lakes on the Lower Colorado River are about 37% full (thats about 40 feet low!), and it shows.  All the boat docks and marinas are on dry land and there are large islands in the lakes that usually are underwater.  Below is a photo on a more river portion of the lake – you can see where the river/lake usually is, and all the boat docks on land.  Note the Cretaceous (I think) limestone cliffs that make up the banks of the river.
