Numbering Conventions

The original LUSS sites are marked either in dark red or later ones in orange paint both with a T designation (with the exception of caves 1-50)
e.g. T999

A few others may also have the designation, the club and the year
e.g. T999 LUSS 78

A number of major cave sites are marked with a metal tag with the same designation format.

Due to the nature of early exploration and the large groups undertaking surface work there are obvious gaps between number sequences. 


KAMI sites are numbered according to the area and then the number. 

The sites are not always marked, so location co-ordinates are required.  (there are overlaps / numbering changes between original LUSS sites and subsequent KAMI work.  In general KAMI used EUR50 rather than WGS82)
