The Tamperer featuring Mayhem

John Barnard

We are concentrating our Marilyn and SubMarilyn surveys on those hills with re-ascent between 147m and 153m. Heights were measured with a Leica 530 GPS system. In 2009 we discovered two new Marilyns and deleted Raw Head and Baystones from the list. Survey results are summarised below.

Moel y Gaer was surveyed because if it were higher than 304.9m it would have replaced Mynydd y Cwm as the Marilyn.

Milk Hill was confirmed as the county top of Wiltshire, as it is higher than Tan Hill by 0.24m.

The survey of Hail Storm Hill confirmed the accurate position of the summit of this very flat-topped hill. The south-east top at SD 84093 19015 is 0.12m lower.

The height of Kinder Scout was established by optical estimate from the trig point. The summit position was identified as a small grassy platform on a peaty knoll, but this may not last long due to further erosion.

There were no changes to the list of Nuttalls or Deweys in 2009 but a few were surveyed to confirm their status:
