What about ice pressing down? The repeated glaciations might have pushed in area down and back up several times over 6 million years. Might have even caused that drip to break off.


It's a detailed paper by five highly qualified researchers, with over 100 citations, and thanks six different reviewers.

It seems very likely to me that they would have said something about this theory if it were relevant.


That wouldn't cause the "bullseye" pattern the article describes, would it?

I don't think the recent glaciation got as far south at Utah, anyway.


You may be referring to the ice sheet, but there have been many periods of alpine glaciation in Utah. https://www.sciencedirect.com/science/article/abs/pii/S02773... and https://geology.utah.gov/map-pub/survey-notes/utahs-glacial-...
