End dumps and scrapers were combined to move more than 1.5 million cu yd of dirt and shot rock uphill for a relocation of U.S. 26 near Mitchell, Oregon. About 75% of that material consisted of either a hard, lava-like basalt or an underlying mudflow-type of cemented conglomerate. This article provides further details on the project, including drilling and blasting operations, rock excavation, and production data.
