No other <br /> depth relationships are apparent from the data in Tables 3 and 4. <br /> Squaw Gulch has the highest geometric mean sulfate concentrations of all the drainages, followed in <br /> decreasing order Arequa Gulch, Vindicator Valley, and Poverty Gulch. Poverty Gulch has the lowest pH, <br /> and the highest manganese and zinc. The geometric mean concentrations for these four analytes in <br /> each of the drainages are shown in Figure 5. <br />
