This multi-cache involves getting information from the Periodic Table of Chemical Elements. To proceed from the start (E1) to stage 2 (E2) perform the following formula E2 = (E1 N) + AN of "B" and (E1 W) + AN of "P" [AN = atomic number]. In addition, beginning with E1 there are clues which, when put together, will reveal the coordinates to the Final cache
Observe all common sense desert precautions. Final stage has room for travel bugs.
CONGRATULATIONS to b&ladventures, LPT and TrekstarL on FTF.
