Some really boring links:

Caving Links

Friends Links

Oh, and if you're really bored you can read my 3rd year project A detailed theoretical and practical investigation of a digital clinometer for cave surveying (PDF format).

...or you can read an article I wrote about GPS for cavers

...or a rambling explanation of geodesy for the benefit of cave surveyors that I wrote on the survex mailing list (PDF format).

...or you can read my thesis.
