In reply to ON3WAB:
You raise a couple of interesting points…
Regarding your question about Hontonberg, Johan (the ON AM) and I have checked this very carefully. The summit is part of a huge undulating “plateau” with a number of highest spots within a few meters vertically of the highest elevation.
Hotonberg is the highest spot but the next highest spot is a meter or less lower. This is checked on the national survey data as well as SRTM data. So although it does not look like it, Hotonberg does have prominence but as part of a large flatter area. This is not unlike summits like Detling Hill in the UK.
As for Kemmelberg, unfortunately topographic prominence does not respect political boundaries… the former is fixed but the latter can of course move
This rule is applied to all associations and for example there are DL summits that are parented by OE summits and PA summits that are parented by DM summits. In this instance Kemmelberg is parented by Mont des Cats in France. With flatter regions, it is quite possible that a parent summit that negates another could be a very long way away.
I hope this explains and is useful to those that have an interest. If you have any further information to add to the discussion above, I’m sure Johan would be pleased to see it.
