At Base Camp</h2>
|
|
|
|
|
|
|
|
|
|
<p>The original notes and sketches should be filed in a clearly marked
|
|
|
|
|
envelope - don't take them out until you are ready to draw up, and put them
|
|
|
|
|
away again as soon as you have finished. They may never be referred to again,
|
|
|
|
|
but ultimately they are the most valuable record of your survey and are kept
|
|
|
|
|
for reference if there is ever a problem.
|
|
|
|
|
|
|
|
|
|
<p>Take the printed centre lines and redraw the survey round it, working from
|
|
|
|
|
the original sketches as if this was to be the final published survey. You
|
|
|
|
|
can "invent" details like boulders in boulder-strewn passage, but otherwise,
|
|
|
|
|
draw only what was recorded faithfully in the cave. If this makes your
|
|
|
|
|
drawing look bad - record more next time ! If things really are unclear,
|
|
|
|
|
consider taking a copy of this drawing back into the cave to clarify it.
|
|
|
|
|
|
|
|
|
|
<p>Make sure the drawing clearly shows the point of connection to previous
|
|
|
|
|
surveys (look at the relevant drawing in the old survey book to ensure the
|
|
|
|
|
sketches match and you really have connected where you think). Make sure you
|
|
|
|
|
note which Question Mark was addressed by this survey and show the location
|
|
|
|
|
of any new question marks, with an estimate of quality and any difficulties
|
|
|
|
|
which will be encountered (eg. if it is a climb, are bolts going to be
|
|
|
|
|
needed ? If a dig, is it a few loose boulders or a crawl over mud ?)
|
|
|
|
|
|
|
|
|
|
<p>CUCC use a set of symbols pretty close to the standard ones promulgated
|
|
|
|
|
by the BCRA, with occasional differences - such as large-enough boulders
|
|
|
|
|
which are sketched to scale using the US symbol. The current state of
|
|
|
|
|
standardisation for cave survey symbols (a useful guide to what we should
|
|
|
|
|
be using where possible) has been documented by
|
|
|
|
|
<a href="http://www.olsen.ch/~devon/uis/misc/praezis/">Häuselmann,
|
|
|
|
|
Weidmann and Ruder (1996)</a>, but this is up for discussion in 1997.
|
|
|
|
|
An alternative set of standards can be seen from the
|
|
|
|
|
Australian Speleological Federation
|
|
|
|
|
<a href="http://rubens.its.unimelb.edu.au/~pgm/asf/stdsurv.html">here</a>.
|
|
|
|
|
|
|
|
|
|
<p>Make sure that you draw both plan and elevation (the latter should be an
|
|
|
|
|
extended section, rather than a projected elevation) for horizontal passage.
|
|
|
|
|
For pitches, several plans at different levels may be easiest (rather like
|
|
|
|
|
the cross sections at each survey station used in horizontal passage). Also
|
|
|
|
|
projected elevations may be useful in addition to the extended section.
|
|
|
|
|
|
|
|
|
|
<p>Write a <b>passage description</b>. This should be detailed enough to be
|
|
|
|
|
followed by someone in the cave who hasn't been there before, and should
|
|
|
|
|
include all passage names, lengths of pitches and climbs, compass directions
|
|
|
|
|
when this makes left/right/ahead clearer. If your passage is a connection
|
|
|
|
|
it is worth while writing descriptions from both directions. It will be
|
|
|
|
|
regarded as helpful if you actually type this description into a computer
|
|
|
|
|
rather than writing in the survey book - but make sure it can be found again!
|
|
|
|
|
In written descriptions, underline passage names the first time they are
|
|
|
|
|
mentioned, or when they are "defined".
|
|
|
|
|
|
|
|
|
|
<p>Complementing the passage description in vertical bits is a <b>Rigging
|
|
|
|
|
Guide</b>. This is usually easiest to do as a sketch, but include notes to
|
|
|
|
|
ensure that all bolts can be found again, and all natural belays recognised.
|
|
|
|
|
Ideally, the knots should be left in ropes removed at derigging, so they can
|
|
|
|
|
be <b>measured</b> for the rigging guide. Remember to do this before undoing
|
|
|
|
|
the knots for rope-washing. Although a good survey and details of the belays
|
|
|
|
|
can be used to estimate the length of rope needed, this is no substitute for
|
|
|
|
|
measuring how much rope it actually took to rig !
|
|
|
|
|
|
|
|
|
|
<p>If you did all that properly, there should be very little left to do in
|
|
|
|
|
the UK, unless you have volunteered to help with drawing up the final survey.
|
|
|
|
|
However, it is as well to check that you have done all you can before BCRA
|
|
|
|
|
conference, by reading the <a href="athome.htm">Back in the UK</a> page.
