Quick Summary

The Absaroka Sequence is a geological term referring to a sequence of rock layers deposited during a period of epeirogeny, which is broad regional uplift of continental crust. This sequence spans from the Late Carboniferous to the mid-Jurassic periods, approximately 320 to 176 million years ago. The Absaroka Range in the Rocky Mountains is a prominent geological feature resulting from volcanic activity and subsequent erosion. This range, extending through Wyoming and Montana, is characterized by high peaks and is a source for several rivers. The formation of such sequences is linked to large-scale adjustments within the Earth's crust.12
