Do you remember as a child playing a game where someone would hide something and you'd have to find it by getting clues on how close you were to the object.
"Cold, colder, warm, cold, hot, hotter, boiling"
Well to find this cache you have to do the same thing. Use the checker below to narrow in on the cache, until you're at the point where you're boiling.
Use the posted coordinates as a starting point.
Thanks to The Rats for the idea behind this one.
Congratulations to BenM70 for being the FTF and Cachedin NQ for achieving the first green tick in the checker.
