Notes
1 Date of change to the list. Changes before 2006 were publicised in the Hillwalkers' Register Annual Report in Strider magazine for the year given. Thus "2000" means the hills were added or deleted in the HR Report for 2000, published in April 2001. The HR Report for 1999 states that there are 373 Deweys, as in Michael Deweys' original publication of 1995. From 2006, changes were announced on the rhb egroup.

2 Names in red indicate a subsequent reversal of status. Links are to entries in the Database Notes or postings on the rhb group. Where 's' is given in the next column, a survey report will be available (these can take a while to appear after the survey)

3 Codes listed below. An asterisk (*) denotes supporting data obtained at a later date.

Acknowledgements
I am grateful to the authors of the following sources for the history prior to 2006:
  • Two files dated 25 May 2006 uploaded by Rob Woodall to the rhb group, which were the primary source from which additions and amendments were made
  • David Purchase's records, including the Hillwalkers' Register Annual Reports
  • Details of surveys by Myrddyn Phillips with staff and spirit level in 2000-2003
  • Michael Dewey's list dated November 2007, which resolved some name conflicts and confirmed that Pen y Bedw was not relocated prior to the survey in November 2008.

An Excel file with further details is available on request.
