I read about that somewhere; maybe in an old Compass and Tape. Basically you just hold the clino body agains a dip bed and measure away; same with the compass for strike. The difficulty comes when the cave passage wall does not run directly down dip; I think you then have to locate the same strata on the opposite wall and draw an imaginary horizontal line between the two and clino at right angles to that. Not as easy as it sounds. Of course, dip/strike may vary throughout the cave.
