For months, two geologists had left their motel at daybreak, heading out in their pickup into the sage-covered hills of the Tuscarora Mountains. Folks in Carlin all knew the geologists were searching for gold, and that made the old-timers smile because they had futilely searched those same hills for gold themselves. The geologists, John Livermore and J. Alan Coope were looking for a specific
