Figure 10. Photographs of sample sites; people for scale. A, Outcrop just above Mather Gorge is fluvially rounded and polished, indicating little loss of mass from the surface since initial exposure. Sample GF-117 was collected here. B, Shattered outcrop of schist showing possible evidence of frost weathering. This is a common morphology for outcrops downstream of Black Pond. Sample GF-75 was collected near here. C, Outcrop from which sample GF-86 was collected is covered for the most part by fine-grained sediment. Fine-grained red soil is exposed behind the outcrop, which stands only 20 cm (8 in) above the ground surface.
