We should see the Three Tooth Cinquefoil (Potentilla tridentata) in flower.
It is listed in Herbaceous Plants of MD for Prince George's and Montgomery Counties.
Flora of WV lists it from 4 counties on "exposed summits at high elevations".
It appears to be a part of MD flora but isn't on the rare list.
