Does anyone know what it is? There are about 5 bunched at the end of the trail near Soapstone.
It's not a trail marker. They're too close together and don't look like any of the other markers I've seen on other Reston trails.
I did a Google image search with it, and it found nothing. Thought it might have been a character from Hebrew/Cyrillic/Arabic script. I even thought it might have been a letter from the fictional Star Trek language, Klingon.
Any other ideas?
