||ShadowAce couldn't find CZ1856
Today I received permission and an escort to get on the building. We searched using the measurements provided in the description of the marker:
[i]35.5 FEET SOUTHWEST OF THE NORTHEAST CORNER OF THE BUILDING, 34.5 FEET WEST OF THE EAST EDGE OF THE BUILDING, 8 FEET SOUTH OF THE NORTH EDGE OF THE BUILDING AND IN THE CENTER OF A WIRE MESH ENCLOSURE.[/i]
This area no longer has the enclosure and no nail could be located here. The images provided show the outline of the enclosure in the roofing material, my PDA and my benchmark coin.
Other images show the roofs general condition, but no nail was located.
