Observation Narrative
Plot captures the upper portion of a 3-acre woodland / barren complex over Catoctin metabasalt on the eastern flank of the Blue Ridge. The woodland is open and stunted, occupying a steep slope, with large, rocky, herbaceous openings. Phacelia dubia has all died back, but covers more area in the spring. Another 3 acre woodland / barren complex is about 250 meters to the northwest.
