A conflict in correlation of coal beds dating from 1914 is reexamined with-die aid of new core hole data, photogeologic interpretation, a broader understanding of the stratigraphy, and brief field studies. It is concluded that die known coal beds in Squaw Basin are of limited lateral extent and are older than those exposed at Eden Ridge. Similar coal beds may be found in other rocks of the Tyee Formation in this area. More core drilling could be justified. in Squaw Basin for coal. It necessarily places considerable emphasis on observations made in 1914 and on details of correlations of beds. T. 33 S., R. 11 W. overlaps the Agness and Marial 15-minute quadrangles and the Coos Bay and Medford 1:250,000 scale quadrangles. Sees. 1-6 are missing from the township, but sees. 7, 18, 19. 30. and 31 are about 13/4 miles wide. The area of the township is about 32 square miles. Most of the township is in the Siskiyou National Forest. The South Fork of the Coquille River and its tributaries, including Squaw Creek, drain much of the township. This river drops from 2,100 feet to 800 feet altitude within the township as it loops around the south end of Eden Ridge. The Rogue River is present in the township in sees. 25, 35, and 36, at an altitude of about 240 feet. It drains, most of the southeast corner and south border areas of the township. The divide between the Coquille and Rogue Rivers is Panther Ridge, which includes Bald Knob and Coal Butte. The boundary between Coos and Curry Counties follows this ridge (pi. 1).-The high point on this ridge within the township is about 3,700 feet altitude. Access to the township is through the Coquille River valley by an unpaved two-lane road south 11 miles from Powers. This road continues south to Agness on the Rogue River. A new highway up the Rogue River to Agness from the coast is under construction. A single-lane road leads eastward to Grants Pass, following the Coquille River within the township. Logging and forest lookout roads give limited, temporary access to much of the township. Heavy timber or dense brush and soil conceal most rock

When the first Outer Continental Shelf leases were issued in 1954, the oil industry was operating near shore in shallow waters. Although regional OCS Orders issued under the regulations have been kept reasonably up to date with advancing technology, the Secretary's regulations had not undergone a complete review by the Department and the interested public since May 1954. The Santa Barbara public since May 1954. The Santa Barbara event triggered the complete review of both the regulations and the OCS Orders. The new regulations and orders not only reflect technological changes but also changes in public attitudes toward preservation of our environment. Of particular interest to petroleum engineers are the provisions petroleum engineers are the provisions requiring much more detailed attention by the Geological Survey to company plans and equipment for prevention of pollution and blowouts before drilling may begin from platforms or mobile rigs. This includes increased Survey attention to the estimated depths to the top of significant markers; to depths at which water, oil, gas and mineral deposits are expected; to the proposed blowout prevention, casing, mud, and cementing programs; and to chokes and similar shut-off devices in wells and pipelines. While some call the new regulations harsh and tending to reduce exploration incentive, most industry spokesmen, we believe, find them to be a simple extension and clarification of practices that responsible oil producers have generally adhered to for producers have generally adhered to for years. If the new regulations have much to say about preventing blowouts and spills, is there any operator who would knowingly run a chance of a blowout? The very small ratio of spills to offshore wells drilled answers the question for the most part, but the fact remains that blowouts and spills do occur, that their potential for damage is great, and that every reasonable precaution must be taken to prevent their occurrence. The new regulations reflect the oil and gas industry's concern for conducting operations that do not interfere with the rights of others, and its responsibility for corrective action when things go wrong.
