Exploration Basis
A series of core holes were drilled from 1984 to 1988 as a part of the Continental Scientific Drilling Program (CSDP) to better understand the stratigraphy, structure, hydrothermal alteration, and subsurface architecture of the Valles caldera. Several authors have reported results from these core holes, including Goff et al. (1986, 1987), Gardner et al. (1987, 1989), Hulen & Nielson (1985), Hulen et al. (1988, 1989), Musgrave et al. (1989), Rowley et al. (1987), Shevenell et al. (1988), and Starquist (1988).
 
Notes
CSDP core hole VC-2B was completed in 1988. Core hole VC-2B was drilled on the western flank of the caldera's resurgent dome, and penetrates the deep liquid-dominated portions of Sulphur Springs hydrothermal system. The well was continuously cored to 1,762 km elevation with 99.2% core recovery.
