The Permian (Guadalupian) Brushy Canyon Formation consists of 460 m (1500 ft) of basinally restricted, deep-water sandstones and siltstones that onlap older carbonate basin-margin deposits at the northwest margin of the Delaware basin. The formation is exceptionally exposed along a 40-km (25-mi) outcrop belt in the Guadalupe and Delaware Mountains, west Texas. The outcrop belt forms an oblique-dip transect from the slope to basin floor, which enables analysis of variations in channel styles and sandstone-body architecture across the depositional profile (Zelt and Rossen, 1995; Beaubouef et al., 1999; Gardner and Borer, 2000; Gardner et al., 2003). This paper includes representative examples (summarized in Beaubouef et al., 1999) of channel complexes deposited in interpreted middle-slope, toe-of-slope, and basin-floor (transitional, channel-to-sheet) environments.

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
