Observation Narrative	The plot captures a small "prairie" on a bedrock ledge at the top of nearly vertical cliff, just upstream from the access road to Sandy Landing at Great Falls Park. The ledge is situated about 8 m in elevation above the river and is only ca. 15 m wide. On the upslope side is a diverse, rocky oak-hickory forest.
