Observation Narrative	This plot is located on a sloping shelf weathered out of the face of the cliffs lining Mather Gorge. Many linear crevices and a few very small pools are present in the bedrock surface substrate. Vegetation is a prairie-like shrub herbaceous association dominated by Hypericum prolificum, Physocarpus opulifolius, and Andropogon gerardii. The foliose lichen Xanthoparmelia cf. conspersa dominates the drier rock surfaces, while the bryophyte Grimmia laevigata forms large mats on surfaces and in crevices that carry periodic running water.
