Rocks for WyattUploaded by: Jason_Petula On: 1156064384 File Size: 39913 Comments: 0 / Views: 949 Description: A great number of bad weather days have restricted us to camp because it is too dangerous to clamber up the bluff to the quarry. With little to do at camp, I often explore the gravel lined beaches of the Colville River searching for interesting rocks for my two-year old son Wyatt. These are examples of the many colors of rocks found along the river. |
Bone Quarry ProgressUploaded by: Jason_Petula On: 1155105455 File Size: 62440 Comments: 0 / Views: 950 Description: This is photo of the bone quarry from the ridge we use to climb to the top of the bluff. When we first arrived, most of the white jacket was buried beneath sediment. We have done a lot of excavating, but much more is necessary to facilitate the removal of the jacket from the bluff. |
Bone with Tooth MarkUploaded by: Jason_Petula On: 1155088525 File Size: 47505 Comments: 0 / Views: 908 Description: Tony discovered something today that everyone found interesting. He uncovered a bone with a bite mark on it. This is an important find because it offers evidence that there were carnivores in the ecosystem. |
Jason at QuarryUploaded by: Jason_Petula On: 1155087998 File Size: 60443 Comments: 0 / Views: 949 Description: The quarry not only contains dinosaur fossils, but also clues about the dinosaur's environment. The rocks that encase the dinosaur bones are all fine-grained - suggesting a low energy environment. | ||
Occipital CondyleUploaded by: Jason_Petula On: 1155021128 File Size: 68150 Comments: 0 / Views: 987 Description: This is a photo of a bone found today called the occipital condyle. It is a very important find because it is an easy way to not only identify the species as a pachyrhinosaur, but also that it is a skull. This particular bone is located at the base of the skull and attaches to the vertebral column. |
Bath TimeUploaded by: Jason_Petula On: 1154992435 File Size: 26432 Comments: 0 / Views: 913 Description: Excavating in the quarry all day produces a lot of sweat and blisters. There are two options for dealing with a dirty person: (1) Wait a month until returning to town where there is running water, or (2) Dunk your head into a frigid river and scrub up. The water is vividly cool, but also very refreshing! |
Dave's Frustration...Uploaded by: Jason_Petula On: 1154991712 File Size: 42121 Comments: 0 / Views: 953 Description: Dave has been resolving problem after problem with the boat motors. He is understandably frustrated. Nonetheless, he keeps his cool and always comes up with a solution. For instance, he managed to repair the boat from yesterday's accident. | |||
Hauling Jackets up the...Uploaded by: Jason_Petula On: 1154990855 File Size: 63968 Comments: 0 / Views: 826 Description: Once a portion of the slab has a jacket around it, the next step is to haul the jacket to the top of the bluff. The bluff's top is approximately 50 feet above the quarry. This jacket weighs about 250 pounds and took five men to haul to the top. |
Accident on the RiverUploaded by: Jason_Petula On: 1154990232 File Size: 58893 Comments: 0 / Views: 946 Description: Landing inflatable boats on gravel bars is relatively straight forward because the rocks have been weathered round. However, the landslides from the bluffs introduce new rock to the river that is sharp and angular. One of the boats accidently hit one such rock hidden beneath the surface. The impact was great enough to punction the material and damage the boat. Dave towed the boat back to camp to begin repairs. |
Jason Uncovering a Din...Uploaded by: Jason_Petula On: 1154989572 File Size: 68403 Comments: 0 / Views: 920 Description: Layers of rock and sediment are carefully removed from the quarry. When a suspect bone is found, the matrix removal process slows down. Often, it is necessary to use brushes to slowly reveal the bone. In this case, a portion of the skull is revealed. |
Kent Holding Bone Stil...Uploaded by: Jason_Petula On: 1154988775 File Size: 47292 Comments: 0 / Views: 934 Description: Kent is holding a newly uncovered bone still in the matrix. The matrix is the rock surrounding the bone and is usually removed by a preparator. Removing an entire dinosaurs from the matrix can take months, if not years of careful labor. | ||
Loading Boats at UmiatUploaded by: Jason_Petula On: 1154760609 File Size: 45572 Comments: 0 / Views: 858 Description: The boats were too heavy to man haul the mile stretch from Umiat to the river. We decided to use an unusual looking machine pulling a water tank for the camp. The machine is equipment with four-foot tires that allows it to cross the muddy path to the river. Lifting the boats atop the tank was no easy task. |
Landing at UmiatUploaded by: Jason_Petula On: 1154759656 File Size: 40870 Comments: 0 / Views: 998 Description: Umiat is a permanent field camp located on the North Slope of Alaska. The story of Umiat's origin varies depending on who you ask. The most common story I heard was that it used to be a military camp used primarily by the Navy as a fueling station for petroleum expeditions further north. Now, it is shared by a variety of groups. The only odd thing about the camp is that a group of workers are inciderating dirt. One graduate students thinks the dirt may be contaminated with fuel from when this was used by the military. Maybe a little investigating on the Internet will reveal the true story. | ||||
Kent Using Rock SawUploaded by: Jason_Petula On: 1154758830 File Size: 42193 Comments: 0 / Views: 994 Description: Kent uses a rock saw to cut the massive jacket into a more reasonable size. Once the jacket is cut, the team will begin under cutting the rock slab to release it from the larger unit. The portion Kent is cutting contains the head of a pachyrhinosaur. |
Climbing the BluffsUploaded by: Jason_Petula On: 1154747282 File Size: 35035 Comments: 0 / Views: 999 Description: Kent and Tony climb up the bluffs to the Kikak-tegoseak quarry. Climbing the bluffs is challenging because the sediment is lose and muddy. One slip and a person could easily tumble up to 300 feet into the Colville River. |
Kikak-tegoseak dinosau...Uploaded by: Jason_Petula On: 1154746867 File Size: 46542 Comments: 0 / Views: 1002 Description: This is the Kikak-tegoseak dinosaur quarry. Kent (Preparator) and two graduates students from Southern Methodist University Thomas Adams and Chris Strganac jacket a pachyrhinosaur skull and other fossils with burlap and plaster. |
Entering the Brooks RangeUploaded by: Jason_Petula On: 1154745769 File Size: 35326 Comments: 0 / Views: 890 Description: We flew a Cessna Caravan from Fairbanks to Umiat. The flight was beautiful, especially the portion through the Brooks Range. The pilot flew low allowing us to see the landscape in great detail. I even saw some Mountain Sheep. | ||
