Y-Line rock pit 1 rehabilitation project: unit 89-4
Johnson LE. 1990. Y-Line rock pit 1 rehabilitation project: unit 89-4
This report is one of a large group containing details of individual projects done as part of the major rehabilitation efforts in the Redwood Creek basin, Redwood National Park, California. It contains a description of the site (a rockpit on the Y-Line, Devils Creek drainage). After removing enough rock for some of the anticipated rehabilitation needs, work crews recontoured the rock pit and spread straw mulch in preparation for planting trees. The report describes the rehabilitation work at the site (with location and topographic maps, tables of costs). Some work at mid- and lower-level sections of the rock pit remains for the future. Background information on file for each site includes photopoint files (photopoint maps and description of locations for documentary photographs), color slides (the work process, before-and-after documentation), administrative files (calculations of volumes for excavation, equipment/hours/costs, daily logs, contracts, etc.), detailed geomorphic site maps (unmarked mylar base maps with overlays), and aerial photographs.
