Pit 3 <br />Pit 3 is the southernmost or furthest upstream of the five pits. Soils in areas to be disturbed are <br />all Green River series formed in alluvium derived from sedimentary, metamorphic and igneous <br />rock. This series is found in floodplains and terraces where Pit 3 is located. Data for annual dry <br />weight production of the vegetation supported by this series is not available. <br />Table 4.
