Every show cave, mine or subterranea on this site has a short list
of hard facts called Useful Information.
With a contemporary browser it will be displayed like this text, with
smaller font and darkgreen letters on white background.
In the Useful Information block you find information in a very brief form, which makes some explanation necessary.
It is very difficult to write dates, fees and hours in a well readable manner, so we always tried to find a sort of "international" way of writing it, which should be understood by anybody. But if you do not understand it, here is the explanation:
All kind of statistic data about the cave or mine.
|L||lenghth over all.|
|VR||Vertical Range: height difference of the whole cave, difference between highest and lowest point, given in meter.|
|D||biggest Depth below surface.|
|T||Temperature of the cave in centigrade (degree Celsius).|
|A||Altitude: the height of the cave entrance is given in metre asl (above sea level).|
|Ar||Area: the area is given for certain sights like dolines, given in square metre m².|
|⌀||Diameter: the diameter sign is a circle with a slash, which is a quite straigh forward visualization of the meaning of diameter. It resembles the scandinavian letter Ø (O with a slash), but it is not the same sign.|
Many other statistical values like size of the area in which the cave lies, size of the floor in sqaure meters or volume of the cave are sometimes used. They are not very useful, as there is no method to gather them exactly. So they depend often on the enthusiasm of the surveyor. On the other hand, the above criteria, like length and depth, are easy to compute from the surveying data. I will not add other information than the ones listed above without a good reason.
All dimensions are given in the metric system.
