Valley of the Angry Fingers (& a Geo-challenge)

Valley of the Angry Fingers (& a geo-challenge)

Angry Finger, one of many.  Gods were nowhere to be seen.

In April I toured the Valley of the Gods in southeast Utah, east of Utah Highway 261 below the Moki Dugway.  It’s underlain by the Cutler Formation … actually it’s called “lower Cutler beds” here because geologists can't agree on a name(s).  The rocks are Pennsylvanian-Permian in age, roughly 300 million years old.  It's a red landscape: red soil, red cliffs and eye-catching red pinnacles, many of them named.

We're in the habit of naming rock outcrops that have suggestive shapes.  There are plenty here, thanks to the erosion-resistant Cedar Mesa sandstone, which provides protective caps for softer Cutler rocks.  Santa Claus, Rudolph, a rooster, a setting hen, a bell, a battleship, seven sailors, and De Gaulle and his troops all reside in the Valley of the Gods, which prompted the question: “where are the gods?”  Then I came upon the Lady in the Bathtub and was really puzzled.

That's the Lady in the Bathtub?!

Turned out my perspective was wrong, as I had driven in from the west.  I needed to go a little farther, and a little further around the bend.  There she was … a Cedar Mesa beauty luxuriating in a Cutler bathtub.

More interesting to me was the curious feature in the rock layers near the base of her bathtub – this is the geo-challenge (I have no answer at this point).

These are typical lower Cutler beds, with alternating layers of mudstone, sandstone and limestone.  Was there a depression in the surface where the sand and limy sediments were deposited?  Or was the underlying layer deformed later?  Any modern-day examples?Sources (in addition to links in post)Fillmore, Robert. 2011.
