Trip highlights:

  • Soda Lake Maar: Soda Lake fills a phreatic (steam) explosion crater caused by a magma injection into the water table. A blast megatons in size created the nearly mile-wide crater west of Fallon.
  • Project Shoal Nuclear Test Site: A 12-kiloton nuclear device detonated in 1963 east of Fallon created a 50-meter-wide cavity in solid granite. Within months the cavity had collapsed to within 250 m of the surface. Has it collapsed any more?
  • Dixie Valley Fault, 1954 Rupture: The magnitude-7 earthquake ripped along more than 60 km of the Stillwater Rangefront. The unusually wide graben along with many other data sets suggest a low-angle, pure normal-fault rupture.”
