Detailed mapping of over 8000 square kilometers and logs from 20 core holes were used to determine the distribution and thickness of basalt flows and interbeds in the Pasco Basin. The data indicate the high-MgO Grande Ronde Basalt and Wanapum Basalt thicken from the northeast to the southwest. Deformation began in late Frenchman Springs time in the Saddle Mountains along a northwest-southeast trend and in Roza time along an east-west trend. By late Wanapum time, basalt flows were more restricted on the east side. Saddle Mountains Basalt flows spread out in the basin from narrow channels to the east. The Umatilla Member entered from the southeast and is confined to the south-central basin, while the Wilbur Creek, Asotin, Esquatzel, Pomona, and Elephant Mountain Members entered from the east and northeast. The distribution of these members is controlled by flow volume, boundaries of other flows, and developing ridges. The Wilbur Creek, Asotin, and Esquatzel flows exited from the basin in a channel along the northern margin of the Umatilla flow, while the Pomona and Elephant Mountain flows exited between Umtanum Ridge and Wallula Gap. The thickness of sedimentary interbeds and basalt flows indicated subsidence and/or uplift began in post-Grande Ronde time …

The 20th meeting of the Association for Energy Systems, Operations, and Programming (AESOP) was held in Gatlinburg, Tennessee, on April 24 to 26, 1979. Representatives of DOE Headquarters discussed the effects that new security and privacy regulations will have on automatic data processing operations. The status and future possibilities of the Business Management Information System (BMIS) were also discussed. Then representatives of various DOE offices and contractors presented reports on various topics. This report contains two-page summaries of the papers presented at the meeting. Session topics and titles of papers were as follows: Washington report (New ADP issues; BMIS: the Business Management Information System; Nuclear weapons and the computer); Improving the productivity of the computing analyst/programer (What productivity improvement tools are available; Rocky Flats experience with SDM/70; Albuquerque Operations Office experience with SDM/70; Planning and project management; Minicomputer standards and programer productivity; MRC productivity gains through applications development tools); User viewpoints and expectations of data processing (User perspectives on computer applications; User viewpoints on environmental studies; Planning and implementing a procurement system; Two sides of the DP coin); Data base management (Use of data base systems within DOE; Future trends in data base hardware; Future trends in data base software; …
