H2002-27-22 Part 3, Gil Mull talks about the differences in geological fieldwork between public / academic,differences in how projects are managed between private versus public sector, his memorable experience while traveling via helicopter to a remote field site and the importance of having an experienced pilot, some life threatening experiences during his fieldwork and the hazards of geological fieldwork, the excitement of geological fieldwork and challenge of exploration, the issues of oil exploration affecting moose and caribou populations in the North Slope and stories about bear encounters, and communication used and the rigorous safety standards.

H2002-27-22 Part 4, Gil Mull talks about geological fieldwork being very collaborative, his employment with the USGS, geological exploration of ANWR, background information on the National Petroleum Reserve in Alaska, field geologists, drilling engineers, oil wells, oil exploration funding, limited access to information and career change, his employment with the Alaska State Geological Survey and background information on state land use for oil exploration in Alaska, assessing and comparing areas for oil exploration in Alaska using past and present geological data, his employment history, and the contributions of geological fieldwork.

H2002-27-23 Pt.1 Gil talks about fieldwork on the North Slope, Gates of the Arctic National Park area, and the Brooks Range, working on reconnaissance mapping at Chandler Lake, using helicopters for field work, Lisburne limestone, Kanayut conglomerate, Castle Mountain and Fortress Mountain formations, Dahl sheep in Castle Mountain, the park boundaries, meeting Ed Hall in Noatak, archeological site at Tukuto Lake, rock interpretation, purpose of geologic fieldwork, the interpretation of rock units and oil exploration, geology of the Brooks Range, Mount Doonerak structural geology, his favorite places in the Gates of the Arctic National Park and the Arctic National Wildlife Refuge, geological maps for the Brooks Range and the Gates of the Arctic and the geological significance of these areas, features on the geological maps, interpretations of features on the maps, geology of the North Slope, what the colors on a geological map represent in the Brooks Range, North Slope and Gates of the Arctic, and the importance of rock units in interpreting geological time and geological formations of a certain localities.

H2002-27-23 Part 2, Gil Mull talks about the geological map of the Brooks Range, a geological map of the southern Brooks Range, northern Prudhoe Bay and Beaufort Sea, his view of the Gates of the Arctic National Park before and after its classification as a park, the permitting process and policies for conducting fieldwork in the park, importance of geological fieldwork, mentoring students, and the politics of gaining access to the park.
