<center><h1>Austrian H&ouml;hlenkataster</h1></center>
The H&ouml;hlenkataster is a national catalogue of all the documented caves
in Austria. Within it, each known cave has a unique number. This number
comprises two parts - the first part identifies the area in which the
cave lies, and the second part is a number allocated to the particular
cave, roughly in the order of discovery.
<p>The area numbers divide the country hierarchically, the four digits
representing successively smaller areas delineated mainly by natural
physical boundaries. CUCC work in area 1623, in which the "1000" (the
Gro&szlig;einheit) represents the Northern Limestone Alps, "1600" (the
Hauptgruppe - major mountain group) represents the Totes Gebirge, a mountain
area 100km east of Salzburg. The Totes Gebirge falls naturally into three
massifs, and some smaller outlying blocks. "1620" (the Untergruppe or
massif) is the western massif, and within that, "1623" (the Teilgruppe or
part of the massif) is the Loser Augst-Eck plateau.
<p>A cave which CUCC are currently exploring is named "Kaninchenh&ouml;hle",
which has the number 1623/161. There are presently six entrances, and these
are labelled 1623/161A, 161B, 161C, 161D, 161E and 161F. On older
discoveries, these numbers were typically painted on the entrance. This has
become deprecated with the increase in area of the Nature Reserve
(Naturschutzgebiet), and now a more permanent, but less obtrusive, stainless
steel tag is bolted on. These numbers enable anyone coming across an
entrance not only to see that it has been explored, but also to be able to
identify it and look up a description or survey for any cave in Austria.
Each area has one locally-based person responsible for allocating "official"
numbers in the kataster.
<p>Cavers actually exploring caves in an area may use their own provisional
names or numbers (many of which appear in these pages). CUCC use easily
fabricated aluminium tags with our own internal number as a temporary
measure during early exploration.
<p>If caves have been explored by groups not recognised by the local cavers,
or caves have been inadequately documented and may be rediscoveries, then
they may still be known only by old provisional numbers. In our area, there
are a few insignificant caves found by CUCC which have numbers like "B8"
(though we are currently documenting the ones we can actually find more fully
to give them "proper" numbers). Further north, there are numbers like "LA23"
or "BS17" explored by Lancaster University Speleological Society and the
University of Bristol Spelaeological Society respectively.
<p>The Austrians periodically publish summary lists of caves for each area,
and within these lists, each cave has a status code, such as "3/S/E +".
The number represents the extent of the cave on a scale from 0-9, the
letters denote the sort of cave it is, and the symbol at the end stands
for the current state of exploration.

<p>If length and depth give different codes, then the cave gets the greater
of the two.

<hr>
<p>So, for instance, the Kaninchenh&ouml;hle, 1623/161, gets the code
"5/S/E&nbsp;&times;", because it is 22 km long and just over 500m deep (both
rate a "5"), is principally a vertical cave, but also has passages with ice,
and been extensively explored, but there are still many leads to push.
<hr>
<font size=-1><p>Some of our older cave descriptions (mostly for caves we
have not explored and know little about) use an older system:

<li>0&nbsp;&nbsp;&nbsp;length/depth unknown
<li>1&nbsp;&nbsp;&nbsp;caves from 5 to 50m long (Kleineh&ouml;hlen) or deep (Sch&auml;chte)

<li>3&nbsp;&nbsp;&nbsp;caves from 500m to 5km long (Gro&szlig;h&ouml;hlen) or over 500m deep (Riesensch&auml;chte)
<li>4&nbsp;&nbsp;&nbsp;caves from 5 to 50km long (Riesenh&ouml;hlen)
