Uranium Mine Adit #3 - 6067. My EMF meter was sounding the alarm with a reading of .36 uT = 36 mG (milliGauss). With further research (from mindat.org) these were all of the Rosa Group of uranium (uraninite) mines. Interestingly in the description it stated "The presence of asbestos mineralization on these claims with no visible nearby diabase intrusion is somewhat of an enigma." 78.26° F
