What period of time was Shiprock, NM formed?
I am currently working on a project dealing with Shiprock, New Mexico and can not find much information on what period/age Shiprock was formed.
I know that Shiprock is 30 million years ago which would make it possibly during the Late Oligocene period, however I can not gather much information on this period of time that deals anything with the rock. Any input would be greatly appreciated!
it is 27 million years old
or in the mid-Oligocene Epoch
