The Newberry Hotspot Track - a series of volcanic domes and lava flows closely coincident with the Brothers Fault Zone (BFZ) - is of interest because it is parallel to the OWL. Unlike anything on the OWL, these lava flows can be dated, and they show a westward age progression from an origin at the McDermitt Caldera on the Oregon-Nevada border to the Newberry Volcano. Curiously, the Yellowstone hotspot also appears to have originated in the vicinity of the McDermitt Caldera, and is generally considered to be closely associated with the Newberry magmatism.
