Yes it is, and that is one of the reasons I do this, to get the pioneer ones that still can be read before they are too weathered [from design or poor materials, sandstone , wood etc. or moss] and preserve them here. Some are very interesting and sometimes hard to see or find. I can sometimes bring out the letters with some programs but hopefully Hamilton has a master list.
It's kind of sad that some of the stones are impossible to read, considering most people want their lives remembered somehow.
