Hi Neon - good to see you around. This was posted about in #119. Its in the Yellowstone region and continental divide so it is an unstable area and brand new geologically. After a while it will settle to one or the other. In this case I expect during that time the earth will move and it will continue to be unstable. But I guess given a small enough measurement theres going to be a bit of a slight blur at the very edge of any catchment area.
