The Urenui Formation stratigraphically overlies the Mount Messenger Formation. It is exposed for about 20 km (12.4 mi) along the coastal outcrop section, where it is approximately 900 m (2952 ft) thick. The Urenui Formation mainly comprises siltstones, which are generally massive, with bedding often only defined by subtle parting lineations. Benthic microfauna indicate that depositional water depths were middle to upper bathyal in lower parts of the formation and uppermost bathyal near the top. The stratigraphie position, paleobathymetry, dominant lithology, and correlation to clinoform-dominated intervals on nearby industry seismic reflection profiles, all indicate a prograding continental-slope depositional environment for the Urenui strata.

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
