Craig Berwyn (SJ 071 323), only bwlch surveyed
It felt good to be
standing in a bog. I hadn’t done this
for a number of weeks and the heather bound morass where the bog was situated
was a delight with the first purples of bloom and vivid late afternoon greens
picked out by a lowering sun. Not
surprisingly I had the bog all to myself, although the road passing over the Y
Berwyn was no more than a couple of minutes’ walk away. I wondered why more people weren’t stopping
to savour the bog’s delight. They didn’t
know what they were missing.

I wonder if Bog Bwlch
Surveying has ever trended on the Internet, if it hasn’t it should as it has a surreal
appeal all to its self. This particular
bog is connected to the highest point of the Y Berwyn; Craig Berwyn and if not
for the near road it would be a quiet spot, however its water laden depths must
surely be seldom visited other by a rogue sheep or scampering fox.
I’d come prepared with a
ten figure grid reference initially produced by Aled Williams from LIDAR
analysis, and afterward also by myself.
LIDAR only has partial coverage for the area of this bwlch, but what is
covered is sufficient to produce a grid reference within a metre or two of its
critical point.

This was the last of six
such roadside surveys during the day and all under a succulent blue sky and
sunshine to savour. As I left my car I
walked over the road and immersed myself in heather, this can be rather comforting
if soft and especially so if the experience is not protracted. Today was one such occasion, with just a few
minutes spent in the bog laden heather bound morass, just enough to enjoy and
not too much to detract.
Considering the amount
of heathered surrounds it would not be too difficult a task to pinpoint the
bwlch without the aid of LIDAR, but having the all-important ten figure grid
reference led to the critical point and within a few minutes the Trimble was
set-up gathering data.

During data collection I
tried in vain to find a dry patch of ground to stand on, to be fair the bog was
not too bad compared to some whose delights I’ve experienced, but it was never
the less a watery haven.
Once the allotted data
were gathered and stored I closed the equipment down, packed it away and looked
out across the heather to distant hills and a blued horizon, what a stunning
place.
