| Nab Hill (SE 033 323) |
Nab Hill can give an easy
ascent, however if not for the aid of LIDAR, Abney Level and hand-held GPS
equipment you could wander the summit area visiting a multitude of lumps and
bumps trying to determine which in fact is the highest. This is due to the debris of old mine
workings. Outside of these, the upper
hill is typical of the area with heather dominating on an open moor. Nowadays it also has a number of scattered
wind turbines beyond its trig pillar, with the latter positioned on one of the
lumps eastward from where LIDAR indicates the high point of the hill is
situated.
When we set out flashes
of sunlight enhanced the opposing moor across the minor road where John had
parked. The rusted colours of autumn
were on grand display as the sun highlighted slithers of green amongst the
golden yellows and oranges. Although
delightful to look at, it also looked horrifying to walk through as patches of standing
water led the eye toward Warley Moor Reservoir, which added stillness to the
scene.

Our way up was in the
opposite direction to the reservoir, either over or under an intervening blue
barred metal gate that led to a wide green track that took us in to the upper hill. Ahead and on the near horizon was a forlorn
looking wire fence with an immediate drop in front of it, no doubt an abandoned
hole from the various workings hereabouts.

I left before John and
Mark, slowly gaining height as flashes of sunlight struck the land. This time of year can give dramatic effect
when on the hill with low light and succulent colour the order of the day.
Prior to visiting John’s,
I had noted the LIDAR position for each of our planned summits, but on this
particular small walk I only got the Trimble out to zero in to the summit location
as I crested the upper moor, having walked past the quickest route to the top
whilst aiming for what looked like a good possibility which vied for high
point.
Having crested the moor
I took a series of photos as John followed by Mark roughly followed my inward
route. As I did so the grey murk behind
us and to our west looked rather foreboding, it was almost black and no doubt
heralded the next heavy patch of incoming rain.

Before leaving this spot
I checked the LIDAR co-ordinates for the summit against what the Trimble was
showing as my current position, and then continued following the dilapidated fence
around the rim of moor to what was becoming evident as the high point of the
hill. This consisted of a welcome patch
of greened grass situated amongst the debris of old mine spoil and the heather
of the moor.

The summit was a
tranquil spot to wait for my two colleagues who quickly joined me. Before leaving I positioned the Trimble atop
my rucksack which would normally form the survey position. Today however, with the heavy rain fast approaching
I had no intention of gathering summit data, LIDAR would have to suffice.

As I packed the Trimble
away and gathered up my rucksack the first drops of rain skidded our way. My brolly, which I carry on most small hills
when weather dictates, was soon up shielding my camera equipment, the Trimble
and the majority of myself. It was only
a short walk back to the car and when we arrived the heaviest part of the
shower was over, affording a semblance of dryness to sort gear and head off to
the next hill.
