M. Culbertson, hydraulic engineer, U.S. Geological Survey, Menlo Park, Calif., and preparatory work in Alaska (during June 1-18, 1971) was done with the cooperation of Harry Hulsing, district chief, Alaska District. Examination of river crossings between the Yukon River and Prudhoe Bay was done by helicopter, for the use of which I am indebted to Giles McDonald of the Bureau of Land Management. Most of the crossing sites described here were examined in the field, in too brief a time to permit quantitative measurements but long enough to be of much assistance in interpretation of the aerial photographs. Location of the earlier photographs with reference to the terrane was difficult because of the inaccuracy of existing index sheets, but it was greatly facilitated by Ray Krieg of the R & M Engineering Geological Consultants in Fairbanks and by personnel of the Alyeska Pipeline System Office in Anchorage. This report was prepared at Washington University in St. Louis, Mo., with support by Research Grant 8623-EN, Airphoto interpretation of the form and behavior of alluvial rivers, from the U.S. Army Research Office in Durham, N. C.

Since the introduction of side-scan sonar as a tool for ocean-floor surveys, a number of workers have described the occurrence of linear bottom features produced by grounded ice. Such features have been found on modern polar shelves (Skinner, 1971; Pelletier and Shearer, 1972; Kovacs, 1972; Reimnitz and Barnes, 1972; Brooks, 1973), and as relict features (Berkson and Clay, 1973; Belderson and Wilson, 1973; Belderson and others, 1973). Studies of core samples, high resolution seismic profiles, and diving observations indicate that the sediments of the Beaufort Sea Shelf are highly distorted by the action of grounding ice, and that the recurrence rate of gouging is very high. It has also become evident that grounding ice is contributing considerably to the sediment transport processes of modern Arctic shelves.
Sediments from similar environments exposed on the continents today should also contain the record of ice gouging and related processes. Thus it has become apparent that drifting ice is an important agent influencing the sedimentary structures and the sediment transport regime of Arctic shelves today and has been in the past. The diagrams presented here, with supporting evidence in the form of side-scan sonar records, and ice and bottom photos, demonstrate the most prevalent processes and types of bottom features observed on the continental shelf off northern Alaska. As the map shows, most of the shelf is affected by these processes today.
