Just stopped at my old friend the Niland mud spring. It hasn't changed very much since I wrote the story about it on my blog, but it did move far enough westward that they rebuilt the train track in its original location. The old section of Highway 111 is slowly being undermined, but the spring seems to have slowed its advance for a while.
Here the long story (with photos and memes!) if you want to read it. I had fun with it.
