The Nålneset Peninsula section of the Kongsfjord Formation, Finnmark, northern Norway, allows comprehensive bed-by-bed correlation in a series of high-resolution measured sections. The outcrop is composed of high net-to-gross sheet sandstones that are interpreted to have been deposited in a channel-lobe-transition environment (Drinkwater, 1995). This section was previously recognized as forming the inner-fan depositional environment of a major submarine fan (Pickering, 1981), which is preserved at the base of a 3.5-km (2.1-mi)-thick overlying section. The outcrop section illustrated here is one detailed part of the oldest, lowermost part of the Kongsfjord Formation, which shows numerous features representative of the typical channel-lobe transition. It is characterized by a hierarchical arrangement of laterally extensive, often compensating, high and low net-to-gross sheet elements that are tens of meters (many tens of feet) thick. Abundant evidence of extensive dewatering, rapid deposition, internal scouring, bed amalgamation, sediment bypass, and reworking are present (Drinkwater and Pickering, 2001). Separating these elements are thinner, finer-grained sheet elements that are characterized by low-density, strongly parallel- and thinly bedded, layered, low-density turbidites. These are composed of typically silty and very fine-grained sandstone. Outcrop quality allows extensive correlation of both types of sheet elements within the outcrop section. A high-resolution example of these sheet elements has been documented and quantified in this example. The Nålneset section is illustrative for sheet systems in confined-basin environments, or in fan environments at a scale an order or more below that of the fan's gross morphology. Outcrop limitations preclude an absolute determination of the full depositional environment.

Tor H. Nilsen, a red-haired Scandinavian who stood more than six feet tall, died October 9, 2005, at his San Carlos, California, home. This was after a valiant five-year fight with melanoma cancer. He was 63. His ashes were scattered at his family plot in Norway in 2006.
He was born in New York City on November 29, 1941, to Mollie Abrahamson and Nils Marius Nilsen of Mandal, Norway, and was the first of their children to be born in the United States. After graduating from Brooklyn Tech, he earned his B.S. in geology from City College of New York in 1962. While there, his prowess on the basketball court impressed a scout from the New York Knicks, but Tor went on to graduate school and earned his M.S. and Ph.D. degrees in geology from the University of Wisconsin at Madison in 1964 and 1967, respectively. His M.S. thesis was a study of Precambrian metasedimentary deposits in the Lake Superior area, and his Ph.D. thesis was a study of Devonian alluvial-fan deposits of the Old Red Sandstone in western Norway.
Dr. Nilsen’s principal expertise was in depositional systems analysis, stratigraphic analysis, and the relationships among tectonics, eustasy, and sedimentation. He began his industry career in 1967 as a research geologist with the Shell Development Company in Houston, Texas, and Ventura, California, where he worked on the tectonics and sedimentation of Tertiary shelf systems of coastal California. He subsequently spent two years with the U.S. Army Corps of Engineers as the Military
