The investigations undertaken in this project have provided a systematic study of the soils within a broad band of National Park land that includes the watersheds between the Marble and Middle Forks of the Kaweah River and the southerly side of Ash Peaks Ridge. The products of this study are: 1) a reconnaissance (Order 4) soil map and map unit descriptions of the selected area: and 2) ultra-detailed (Order 1) soil maps and map unit descriptions of three sites within the larger area at which long-range, intensive studies on the ecologic effects of acid precipitation are underway. The latter are: the Emerald Lake Area, the Log Meadow Area, and the Elk Creek Area.
