<h3>Taking bearings</h3></center>
|
|
|
|
<p>In the long term, every cave that gets a number should be on a
|
|
<a href="survey/ontop.htm">surface survey</a> carried out to the same
|
|
accuracy <b>and with equally good sketching as the underground surveys</b>
|
|
(see the <a href="survey/index.htm">Surveying Guide</a>). Failing that, a
|
|
good <a href="survey/gps.htm">GPS fix</a> should mean that the immediate
|
|
vicinity can be found again. However, for prospecting and initial exploratory
|
|
work, it is usually good enough to take bearings from the entrance and make a
|
|
good sketch or take photographs.
|
|
|
|
<p>In theory, any cave can be located by taking bearings to two other known
|
|
points. For this to work at all well, the bearings should be as nearly as
|
|
possible at right angles to each other, and the points should be clearly
|
|
recognisable, well-defined and not too far away. As these criteria are not
|
|
always readily met, it is usually worth taking extra bearings on several
|
|
points (ie. at least three) which can be used for confirmation or for
|
|
spotting duff ones.
|
|
|
|
<p>In general, sharp pointy peaks which can be recognised over quite a wide
|
|
area are best, so that the Bräuning Zinken is excellent. Peaks with very
|
|
rounded or multiple summits are generally not useful, so that the Vd.
|
|
Schwarzmooskogel, for example, is particularly bad. In this case, it is
|
|
useful to include a sketch to say exactly which point was used. The apparent
|
|
summit, as seen from Top Camp, is usually called "VSK nipple". This is a good
|
|
50m below the true summit, but appears well-defined. It is fine for finding
|
|
caves in the field but is <b>not</b> adequate for locating them on a map.
|
|
|
|
<p>In the cave descriptions, bearings are quoted with a series of standard
|
|
<a href="abbrev.htm">abbreviations for landmarks</a>, which gives a good
|
|
indication of which ones are most useful.
|
|
|
|
<p>Ideally, take bearings on one of the points identified in the pictures
|
|
below (follow the links to useful sized images on which the peaks are named).
|
|
Failing that, be sure to identify your feature correctly, using a good map
|
|
(ie. the Alpenvereinkarte 1:25000 sheet 15/1, Totes Gebirge West), and write
|
|
down the name in full, preferably with a sketch.

identified the summits on the views with complete certainty :-)
