Core Sampling at VLA Site, 1973
Before any VLA construction began, there was extensive soil testing at the site in the center and along all the proposed arms. Environmental engineering firms, geologists from New Mexico Tech, several local drilling companies, and local excavators were all involved in the multi-month process, and many core samples were extracted for analysis. In this 31 August 1973 photo, the rig from Albuquerque Testing is drilling a test hole on the southwest arm to extract core samples. The Lorenzo well is in the background.
