Since “retirement” in June 2010, Richard has continued to work part time at the Bureau on geologic map projects and related studies that concern Cenozoic volcanism, magmatism and the Rio Grande rift in central New Mexico. Richard’s primary interest is the structural control magmatism, geometry of magma ascent and the evolution of volcanoes, including the 32.5 million-year old supervolcano at Socorro known as the Socorro caldera.
