Corner of New Mexico-Oklahoma-Texas
Many people haven't noticed that the northwest corner of Texas' panhandle is not the same point as the southwest corner of Oklahoma's panhandle. It's because New Mexico "wraps" around the Texas panhandle for a mile or two before it reaches Oklahoma. In this photo, I am standing in Texas (at least I thought so: my assumption was that the USGS benchmark in the foreground is not located at the actual point, but someone wrote to tell me it is. I figured the road behind me is Texas' north state line). Anyway, the northwest corner of Texas' panhandle is a mile or two to the west (left). The dirt road defines the eastern state line of New Mexico: the state has a miniscule "panhandle", if you will. Oklahoma's panhandle is to the right (east) of the road, and north (behind) the fence.
