![]() (1) Today we trached total depth (TD) within the Cononino Sandstone of Permian age. Although core 1 tool less than 3 weeks, it feels like 2 months have passed, since the balmy 70s. |

![]() (2) In the early morning we started coring the crossbedded sandstones Wupatki Mb. or the Moenkopi at 1649 ft. |
![]() (3) At about 1678.5 ft we entered a red mudstone, the lowest part of the Wupatki Member. |
![]() (4) At about 1680 ft we entered the sugary tan sandstone of the Permian Coconino Sandstone, marking a major regional unconformity and signaling we are nearly at TD. | ![]() (5) Core of the Coconino Sandstone. We stopped coring at a depth of 1706.5 ft. | |
Congratulations to all on a successful coring operation! Our original estimated depth to Permian in
our proposal was 1509 ft, and the section was about 171 ft
thicker than we thought at the time, largely accounted for in the
Chinle. |
