The 40 mile desert, beginning here, is a barren stretch of waterless alkali wasteland. It was the most dreaded section of the california emigrant trail.

One of the most geologically intriguing features of the colorado plateau is its remarkable stability. Relatively little rock deformation such as faulting and folding has affected this high, thick crustal block within the last 600 million years or so, although there are some newer features such as the waterpocket fold of capitol reef (estimated 50–70 million years old).
The term pleistocene (most recent) was coined by charles lyell in 1839, on the basis of a section of type strata in eastern sicily, according to the proportion of extinct to living species of mollusk shells in the sediment. Strata with 90 to 100% present day species were designated pleistocene.

Analyzing ancient rna data from a pleistocene canid, we find hundreds of intact micrornas that are taxonomically informative, show tissue-specificity and have functionally predictive characteristics. With an extraordinary age of 14,300 years, these microrna sequences are by far the oldest ever reported.

The most recent ice age occurred then, as glaciers covered huge parts of earth.
Twelve to fifteen sequence boundaries associated with nannofossil extinction were recognized and mapped in the pleistocene - miocene section. The forty mile long ship shoal line shows that the mahogany salt moved to the south into the younger section leaving salt weld and a counter regional fault system to the north and creating the ewing bank.
The crater was created about 50,000 years ago during the pleistocene epoch, when the local climate on the colorado plateau was much cooler and damper. The area was an open grassland dotted with woodlands inhabited by mammoths and giant ground sloths.
