APPENDIX 3. FINAL DRILLING REPORT, APACHE MESA, RIO ARRIBA COUNTY, NEW MEXICO
Virginia T. McLemore
INTRODUCTION
During field investigations June 10-12, 2015, 18 proposed drill hole locations were staked in the field with wooden stakes and flagged with orange, blue, and pink flagging tape. Drilling began on August 18, 2015. A few problems were encountered during drilling and solved. The equipment was moved onto the site on August 18, 2015 and trenches for water were dug. The major delay was when the drill rig ceased to function because of fuses. After trouble-shooting for 1.5 hr, the drillers were able to get the rig going. Drilling on DH1 began on August 19, 2015. Additional difficulties were encountered (loss of circulation, improper core springs) but resolved. Drilling was completed on August 25, 2015. Table 1 summarizes the final completed drill holes. A new hole was located and drilled (DH7) along the road south of DH5 because DH5 did not encounter much black sandstone and I had mapped it to the south. The road was already cleared and the hole was on the road with little disturbance.
