Pen Aran Hill (SO 137 888) |
As with many smaller heighted hills, the upper part of Pen Aran Hill is no more than a relatively high field, albeit a field that gives an extended view. Prior to visiting I had examined this hill via LIDAR and found two tops separated by 1mm in height, each placed at or beside a perimeter hedge and fence. I planned on visiting the two tops and survey each.

Philip had also cut grass in the Long Field and as I accessed it through a gate, great swathes extended across the upper hill in lines leading to its high point. It was only a short distance to the first southerly LIDAR summit. I stopped and quickly assessed the lay of land before continuing to the farther northerly LIDAR summit. It is the latter that many people recognise as the high point of this hill. On my way I came to an intermediary top, again I stopped and looked back and tried to assess its height relative to the other two summits. It seemed that three surveys were necessary to attempt to split these tops.
Continuing to the farther northerly top I used the Trimble as a hand-held GPS unit to zero in to the ten figure grid reference produced by LIDAR. This point of the hill has a hedge signifying the field boundary. The Trimble was soon set up and within a few minutes it was activated to gather data.

As the Trimble gathered data this proved a lovely place to stand and have the world pass me by. Compared to earlier in the morning cloud had now built up with the sun casting light and shade with shadows moving across hillsides adding depth to perspective. I was in no particular rush, but did want to visit Penarron farm which is positioned just below the upper field. I hoped I could find the local farmer and confirm an appropriate name for this hill and therefore once the Trimble had gathered allotted data I closed it down, packed it away and made my way through the swathes of cut grass back to my car.
I was soon parked at the entrance to Penarron farm and walking in to the back yard, where Ivor and Rhydian Powell were encouraging three cows in to a trailer. I volunteered my help and tapped one on its hind quarters, they were soon all safely in, more from the expertise of the two people I had just met rather than from the encouragement that I had given.

Therefore I drove back up the road, parked in the pull-in spot where I had left my car to visit the hill and went through the opposing open gate and down the field where Phil was in his tractor cutting great swathes of grass. I waited for him to head my way and waved over, he soon stopped and we chatted for ten minutes of so. Phil told me the names of the two opposing fields, the Pike and the Long Field and the Big Field for where we now were. I asked him about the name of the hill and he said he knows it as Pen Aran Hill.

The day was progressing well with three hills visited and surveyed and one new hill name and three field names documented. The fourth hill of the day; Cold Weston (SO 141 907); a name given on the Tithe map, required driving back in to Kerry and then a mile or so north-west before heading up the access track to Weston farm where I hoped to find the local farmer to ask permission to park and visit the summit, and hopefully confirm the name of the hill.
