Brand
new all-colour OFD 1 Survey ~
from Chris Grimmett
When you next
visit the Club, take a look in the Long Common Room at the new wall
survey which covers of OFD 1, Cwm Dwr and out as far as Fault Aven.
This is the first part of the cave to have been resurveyed by Brian
Clipstone and a pair of Dobsini, with some assistance from others
then compiled and drawn by Brian followed by a cartographic reworking
from Clark Friend [proof-reading and print organising by Chris Grimmett
- Ed].
The scale is
exactly the same as before but you will see much improved detail,
many more annotations and - it's in glorious Technicolour. The highest
passages are coded in red, graduating downwards to purple for the
lowest. All water, irrespective of its level is in blue - dark blue
for sumps and pale blue for open water. The survey has been printed
on PVC rather than conventional poster paper which should be much
more durable and damp/beer proof.
One aspect that
has already proved very popular is the addition of surface features
including the cottages, The Stump, the track, station and fence
boundaries. This makes it much easier to relate the orientation
of the cave to what goes on above ground.
A well known
law ensured that Twll Gwynt Oer was right where the roof beam runs
across the LCR and the cave had to be moved across a bit with the
aid of a pair of scissors. As the new and old surveys do not quite
line up with each other, cavers doing a through trip between Cwm
Dwr and Top will have to undertake a hyperspace jump to the East
of Fault Aven [do not attempt this when water levels are high].
As the project
moves forward, we are maintaining a log file of any errors or suggested
alterations before any final survey is printed. If you have any
comments on how you think it looks, we would be interested to hear
from you [contact Chris Grimmett].
Here are some thoughts:-
Should we print
the copies for sale in black and white or colour?
Would you pay a premium for colour?
Is plastic a better print medium all round?
Do we include official Fixed Aids on the survey?
By the way,
don't bother telling us that we have mis-spelled Lowe's Chamber
and Passage as Low's. When we did the checking through, we found
that to the contrary, Low's has been mis-spelled as Lowe's for the
last decade or three!
