Your top pic looks like a "T" cross, perhaps representing the crucifixion. Below that where it looks like someone has removed some of the lichen....perhaps the curled up lamb as if sleeping.

Thanks Oddrock. I see the "T" you are talking about. I have looked it over many times and I still am not sure about the lamb. I Think maybe the Pic was taken too close. Hopefully I can get one more trip up there before i have surgery if my knee will hold out. Thanks to you and Billythekidder i have some things I need to pay closer attention to. Many thanks
