Significant Name Changes



This part of the Mapping Mountains site is dedicated to any significant name change for hills that appear in listings that I am associated with.  These are mainly the Welsh P30s that appeared on Geoff Crowder’s v-g.me website and now take in all P30s in Wales and which are entitled the Twmpau (thirty welsh metre prominences and upward), also included are listings that are now co-authored with Aled Williams which take in a number of P15 hills.

This heading will concentrate on the hills that have been surveyed and / or those appearing in listings that have been recently published.  Many of the hills listed in the original P30s on Geoff’s website used names that were invented, subsequently extensive place-name research has taken place and it is now the policy not to invent names and therefore where an appropriate name is found either from local or historical research it will be detailed under this heading.
