The summit field of Pt. 212.2m (SJ 304 530) |
When I say headed for the hill, all this entailed was walking back a few metres up the lane to where a slight gap emerged in the hedge on my right, this would give access to the upper field where the summit of the hill was positioned.
The gap in the hedge proved fun; it had two strands of floppy barbed wire across it and was relatively narrow, with the hedge consisting of thorns. I straddled the barbed wire and delicately picked my way through the hedge with a tug and a pull and eventually emerged on a closely cropped grassy field, which online logs indicate is used as a paddock. When driving toward the narrow lane I noticed a number of horses on the lower part of the field, when on its summit they thankfully remained out of sight.
It was only a short walk from where I had emerged on to the field to the summit. When approaching it I assessed the lay of land and zeroed in on what looked to be the high point, when there I put my rucksack down to mark the position. I then assessed this point from a number of directions and decided to take two data sets, each a few metres apart.
Having set the Trimble up for its first summit data set I walked back toward the hedge a safe distance away from the equipment, so as not to disturb satellite reception, and waited for the allotted data to be gathered and stored.
