grand gulf

 This is the Grand Gulp,  I mean, Gulf. The good picture, above, is by Frank Martin. It is supposed to have geological significance, but I don't know what. It is deep enough that it did cause me to gulp when I was standing by the edge, so I edged away. Apparently where that mud puddle at the bottom is, there is a cave with a lake that you used to be able to go in by boat. Doesn't look that appealing right now, thanks to recent heavy rains. Some geologists did an experiment with dye, and apparently water from half the state away emerged here in the gulp.
