Geocache Description:

The Cache is NOT at the listed coordinates.



In the solution for this puzzle, the number "1" is missing from "152", you just need to put it back in.

To find the beryllium sphere, you must first work out a method of cleaning laser ablation debris.

You must be able to ablate surfaces in a way that simultaneously clears away deposited debris, and avoids subsequent ablation debris accumulation. The debris formed during the ablation process which becomes redeposited at, and adheres to the target surface must be removed from the target surface before the ablation process continues over the remainder of the target surface.

a discrete cleaning step is also required to remove deposited debris from the target surface by exposing said target surface to alternating high and low fluence pulses. BUT, here is the real challenge…. the only equipment you are permitted to use, is a:

Combination sweeper and mulcher


As people are having some difficulty, I have added a clue. GOOD LUCK!! (BYOP)
