Another interesting location near the mouth of the Rio Grande
is visible in Peter's Topozone url below. Notice the 1/2 mile
long oxbow lake about 2 1/2 miles west of the Rio Grande mouth.
It is below sea level. Not much below, probably only -1 or -2
feet but clearly below. USGS lists the Gulf of Mexico as the
low point of Texas so they don't recognize this lower point.
However, having written a guide to the low points in the US
I am trying to get more info on this spot. I may have to
drive down there and check it out.

Sadly, there isn't much for the border anymore to follow anyway... "A
few sticks in that sand", now what sort of border is that?
