Map of the Yellowstone area showing our hypothesized foci of future volcanism in relation to the main National Park infrastructure, roads, and surrounding towns. The numbers 1, 2, and 3aa refer to the three intracaldera fault-controlled lineaments as discussed in the text. See Christiansen et al. (2007) for a discussion of possible future extra-caldera volcanism in the Norris-Mammoth corridor and Mirror Plateau fault zone.
