       To find the location of the marker, from Electra, go north on SH25 from HWY287 less than a 1/4-mile. Past the cemeteries on both sides of the road, the gate is next to Precinct #4 Annex. A Centennial Celebration sign hangs next to the gate. Go through the gate to the west, staying to the left of the abandoned power house, then turn right on the second road. The marker faces C. M. Putnam Lease Well #57, about a 1/4-mile behind the Precinct #4 Annex.
        GPS coordinates to the gate: 34-degrees 05' 56.8" -98-degrees 54' 23.3".
