John, I was looking at some peaks' parent lineages, and it occurred to me that it could be interesting to present the first peak along that lineage that is more prominent than the subject peak. Since this already exists in your data in most cases, I'd think the query would be simple enough, though it could be taxing for your database.
Is what I've described the equivalent to the concept of encirclement/island parentage, or is there something about that definition that I'm not considering?
