Arctic Dinosaur Ecosystem: North Slope, Alaska

Rocks for Wyatt Uploaded by: Jason_Petula On: 1157853035 File Size: 15346 Comments: 0 / Views: 1647 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.	Chris Stops Slip with ...

Most of the trail has slumped into the river and the portion that remains is extremely muddy and slippery.

Cesna 206 Uploaded by: Jason_Petula On: 1156464250 File Size: 42274 Comments: 0 / Views: 2078 Description: A Cesna 206 was used to extract all team members from the field back to Umiat. The large wheels on the plane allowed it to land on gravel bars near our campsite. Unfortunately, it could not land closer to our campsite. As a result, we had to drag ALL gear a few hundred yards, through a tangle of willows, so the plane could be loaded with gear. Each flight carried gear and one person.	Arctic Ground Squirrel Uploaded by: Jason_Petula On: 1156464012 File Size: 68413 Comments: 0 / Views: 1999 Description: The arctic ground squirrel (a.k.a. - sic sic) often visits the quarry. These rabbit sized animals have terrorized the research team for weeks on end using uncanny methods of distraction. A high pitched bark draws all attention to a sic sic next to the quarry. With all eyes focused on the noisy sic sic, its other family members chew through packs to steal lunches.	Plastering in Pouring ... Uploaded by: Jason_Petula On: 1156325089 File Size: 40602 Comments: 0 / Views: 2020 Description: Chris and Thomas add additional pieces of plaster covered burlap to an undercut portion of the pachyrhinosaur skull. Even though conventional methods yield poor results when plastering in cold rain, the team has no choice. The skull most be rolled free from the quarry tomorrow or it will be lost.	Tony Plastering Prized... Uploaded by: Jason_Petula On: 1156324906 File Size: 57733 Comments: 0 / Views: 2064 Description: No longer able to await better weather, Tony races against the clock to jacket and remove a potentially articulated pachyrhinosaur skull. The skull is locked in solid rock and many days have been spent carefully chiseling the skull free from the frozen tundra. If the skull cannot be freed soon, it will be left behind and probably lost to the Colville River as the quarry continues to slump.
Chris with Plaster Hands Uploaded by: Jason_Petula On: 1156324670 File Size: 48565 Comments: 0 / Views: 2067 Description: Our extraction date for this expedition is fast approaching. Because so many days have been lost to poor weather, we are working in conditions not particularly suitable for working with plaster. One method we have used in our race against the clock is heating water on a portable campers stove. Chris Strganac (Southern Methodist University) can be seen mixing plaster with his hands as we race to get a jacket around the skull of a pachyrhinosaur.	Ok to Enter Caribou Lo... Uploaded by: Jason_Petula On: 1156324277 File Size: 54321 Comments: 0 / Views: 2052 Description: Thomas drew on some river rocks so people would know when the Caribou Lounge (i.e. - bathroom) was occupied. This side of the rock implied it was safe to proceed further. Another message on the reverse side of the rock clearly let you know to stay back.	First Helicopter Sling Uploaded by: Jason_Petula On: 1156324115 File Size: 19170 Comments: 0 / Views: 2006 Description: Despite a morning snow storm, we were able to work at the quarry today because the NOVA film crew arrived at camp with a helicopter. The helicopter took us to the quarry so the film crew could get some shots. They offered to take some materials to Umiat for us. This photo shows the first jacket flying from the quarry.

Snow in August Uploaded by: Jason_Petula On: 1156323564 File Size: 31939 Comments: 0 / Views: 1936 Description: Nothing makes you want to get out of your tent in the morning then freshly fallen snow. Weather in the Arctic is unusal. One moment it can be 50 degrees with partly sunny skies. Five minutes later, freezing rain accompanied by bone chilling winds. This is why seasoned researchers always carry a day pack with them loaded with a variety of clothes.	Field Sketch of Pachyr...
