It is bordered on its south by a structure that formed during the Eocene called the Gonave, and its major craton is underlain by the Abitibi greenstone belt. Also subjected to the Grenville and Sevier orogenies, much fault-blocking has taken place on it due to its subduction of the Farallon structure. It includes the Anahim, Jemez, and Raton hotspots, and its surface was covered by the Sundance Sea as well as the Cretaceous Inner Seaway.

The MTJ experiment is being conducted at the northern terminus of another feature found at its western edge. Another feature found on this body contains the world's largest dike swarm, and the southern end of that feature has (*) lobes named Wadena and Rainy as evidence of recent glaciations events. A more notable feature of this geological mass is a large caldera housing a supervolcano that is thought to erupt every 600,000 years. For 10 points identify this geologic mass that includes the Canadian Shield and the Yellowstone Supervolcano, and whose fight with the Pacific Plate causes earthquakes along the San Andreas Fault.
