59K A shelly section of the Beaufort Formation, 3/13/04 |
91K Jean Self-Trail contemplating even more core from the Cape Fear, 3/14/04 |
119K Washing core, 3/15/04 "If it were raining just a bit more we might not need to wash the core." |
68K Jean Self-Trail measuring an interval of Cape Fear core in the tray so it can be sliced up and boxed, 3/16/04 |
62K Core recovered from below 270 feet (near the base of the Cape Fear) showing the clays and interfingered sands, 3/16/04 |
64K Close-up of the core shown in the earlier interval. The sands range from very fine to pebble-sized. There is a nodule of pyrite in the sand interval and Cape Fear colored-clay balls in the underlying silt matrix, 3/16/04 |
94K The casing coming up the hole, 3/17/04 |
87K The extruded core being washed, 3/17/04 |

83K Fossilized root in paleosol zone, 4/13/04 |
78K 4/13/04 |
68K A rock impeded progress most of the day 4/14. On Thursday, 4/15, finally recovered the rock that had been blocking the entrance to the core barrel. 4/14/04 |
77K We had two large rocks blocking the core barrel. One the exact size to prevent core recovery is unusual, two is quite rare. The solution is the entire rod had to be tripped (removed) from the hole in order to retrive the rock and resume successful core recovery. 4/16/04 |

Colleen McCartan updating the sample log. Each time a sample is taken from the core for analysis (such as fossil identification, salinity, percent fines determination, etc.) the depth, size, and scientist are recorded, 3/16/04 |
54K Rob Weems updating the lithologic log on each cored interval after it is recovered from the core barrel and prior to boxing, 3/16/04 |
58K This is a UV light box. The UV light is used to cure the Slide mounting media (Norland Optical Adhesive 61), 3/18/04 |
42K
Jean Self-Trail removing a cured slide which she will examine under a high-powered microscope to check for nanofossils, Nanofossils are used to age date the formations, 3/18/04 |
55K The preserved slides allow for later processing of the samples. It appears that some of the fossils may degrade if they are not preserved quickly. This is one method that is being studied, 3/18/04 |
48K Burning the midnight oil, 3/18/04 |
61K
