Bird tracks at the Sharpsburgh Site.
A large bird track petroglyph is clear and a smaller bird track is just to the right of it.
Lichens obscure the Sharpsburg rock art.
Lichens partially obscure a group of thunderbird at the Sharpsburg site. The petroglyph
on the left edge was described as an "oar-shaped motif" and may have sexual symbolism (Diaz-Granados and
Duncan 2000: 168, Figure 5.46d).
