People assessing significance need to have some experience in comparative examples or case studies - obviously, the more extensive the experience and knowledge of the type of landscape or feature, the better.
If you know all the mining sites in your area, and are confident that you have done the survey, historical research and analysis thoroughly, you may be in the best
position to assess the comparative significance of these mining sites.
However, the comparison would extend only as far as your area or your knowledge reaches.
If you lack Alps-wide experience and knowledge, you will need to get assistance from your
Park Service's history or heritage section, or engage an historian or consultant with appropriate expertise.
Reports and studies, if they exist, may be able to help you reach more general conclusions about comparative significance.
