Description:
Hot (>30 degree C) water has been reported from the Safford
area for at least seventy years. The most notable hot water
occurrence, Indian Hot Springs, is located northwest of
Safford near Fort Thomas. Indian Hot Springs, a health
resort at the present time, includes several hot springs and
an artesian well about 182 meters deep (Knechtel, 1938).
Collective discharge of the springs and well is 320 gallons
per minute (gpm) and the highest published discharge temperature
is recorded at 48.3 degrees C (Knechtel, 1938).
Nearly all wells deeper than 244 meters in the Safford
area discharge artesian water. The deepest of these wells,
the Mary Mack, was drilled in the NW, NE, Sec. 13, T6S,
R.24E during 1929 and was completed to a depth of 1148
meters (Knechtel, 1938). The well encountered water flows
at 495, 524, 676, 707, 978, and 1079 meters (Knechtel,
1938). In 1933, the well discharged 2500 gpm of 58.9 degrees C
sodium chloride water containing 3251 parts per million
(ppm) total dissolved solids (TDS) and 4.9 ppm fluorine
(Knechtel, 1938). Present status of the well is not known
because a field check of the described well location failed
to find the well; but the well has probably been plugged
and covered.
