Mapping Mountains – Trimble Surveys – Brown Clee Hill


05.04.22  Rodge Hill (SO 747 624)

As I locked my car I checked the time; it was 3.40pm as Charles and I left for the ascent of Rodge Hill.  Any warmth from earlier in the day had now been replaced by a chilled breeze and I decided to put my spring fleece coat on, otherwise my upper body and especially my arms would no doubt have felt the chill of mid-afternoon.

Rodge Hill was our fourth hill of the day, and much of the time had been spent waiting for the Trimble to attain its 0.1m accuracy level before data should be logged.  The equipment had been placed in a number of restricted positions; including beside a road, at the bottom of a steep cutting that is now a dingle, next to a bricked building below tall fir trees, and on this hill; beside a tall hedge.  None encouraged satellite reception, during such times Charles had found a sheltered spot to lie on the ground relaxing whilst the Trimble slowly did its stuff.  Not everyone would have been as patient and I appreciated his lack of complaint.

Our chosen route passed close to the connecting col of this hill, we stopped to quickly assess the lay of land and considered surveying it on our way back, if time and inclination was sufficient, it wasn’t, so LIDAR data will suffice.

The public footpath we were now on marched across a large open field, newly planted in crops, following the course of an earthen vehicle track toward an intervening fence.  It then veered rightward, uphill, again following an earthen vehicle track.

Any glimmers of sunlight enhanced the tranquil scene with intermittent flashes of highlighted colour.  The world seemed at ease and for me, this route proved extremely enjoyable.  After gaining the initial height the path met the upper ridge of Rodge Hill.  We now veered left and followed the path all the way to the summit on what is a part of the Worcestershire Way. 

Gathering data at the summit of Rodge Hill

The summit of the hill is positioned beside a high hedge consisting of blossomed hawthorn and the occasion rogue maturing tree.  The high point was relatively easy to pinpoint and once we had done so, Charles retired to a bench dedicated to Ali Staines.  The dedication had engraved tandem bicycles on it and the dates 1963 – 2000.  It was a beautiful piece of wood and understated in its simplicity; a fine memorial to someone’s loved one.

The Trimble took an age to achieve the required 0.1m accuracy level, but once this figure appeared on the screen, I pressed ‘Log’ and stood a safe distance away so as not to interfere with satellite reception and waited for the allotted five minutes of data to be gathered and stored.

During this time a couple with a dog approached, I reassured the two women that I had not just murdered Charles; who had now taken on a prostrate position on the ground.  We chatted for a few minutes before the dog pulled toward Charles, one of the women said ‘she’s going to lick him’, the other laughed and said ‘not me, the dog!’  This brought lots of laughter to the scene. 

This encounter and what was said brought many laughs

The countryside hereabouts had taken on the qualities of spring with new born lambs nuzzled against their mothers, with many playfully jumping around the adjacent field.  The view to our south-west was extensive and the light enhanced the grey overhead cloud giving a pleasing touch to the last few minutes on the summit of the hill.

All that remained was to retrace our steps back down the ridge to the large open field and across toward the connecting col.  As we approached we again assessed its position, Charles asked if I was going to survey it, I knew I wouldn’t as we had one more hill to visit and therefore we continued down to the awaiting car.
