Found 1/4 corner today
Mirrors and Chalk
That is excellent advice Kent, and I thank you for it.
I forgot I had a yellow timber crayon in my vest that would have worked well.
I will bring a better camera and get a better shot when we head back to that corner.

The reason I favor plain white chalk (aside from the fact that it is cheap and high contrast) is that it washes off with no residue whatsoever. So, after highlighting the marks on the stone for photography, in a couple of good rains the chalk ought to be washed completely off. That way, the stone is left in pretty much exactly the same condition in which it was found in case there is some question about the stone for some reason. I haven't used lumber crayon much. Is it water soluble also?

"I haven't used lumber crayon much. Is it water soluble also?"
Here is the MSDS Report for you Kent. It is not water soluble; however, it has been my experience that it will fade with prolonged weathering, and one can purchase water soluble lumber crayon as well.
The benifit of the keel is that it will not fade after a couple of rains, but it will eventually disappear.

Sorry about the delay in responding.
Adam is correct. The crayon is not water soluble, but will wear off after a few rainfalls.
I do prefer an "undoctored" photo of a corner if I can get it. Maybe it is that where's Waldo aspect of trying to find the markings.
That being said the chalk and crayon are excellent tools to make the markings more visible. I usually end up taking one photo without enhancing the markings and one with enhanced markings.
