The 500-Metre Tops of England and Wales – the Deweys

Y Drum (SJ 082 378) – Dewey addition

The listing to The 500-Metre Tops of England and Wales appeared in Michael’s Mountain tables book which was published by Constable in 1995.  This list mixed metric and imperial height in its criteria to bookend up to the 2000ft height band and listed hills between 500m – 2000ft (609.6m) in height with 30m minimum drop.

Since publication of this list there have been a number of status changes to it. In recent years this has involved independent surveyors and the use of LIDAR.  Both have enabled an accurate re-assessment of many of the hills included in Michael’s list as well as potential new Deweys that were considered marginal on height and/or drop and not initially included. 

Michael Dewey is in receipt of the survey details relating to this hill and has confirmed its addition to his list of The 500-Metre Tops of England and Wales.
