**There is nothing at the posted coordinates, you don't need to go there.**
This is a bonus cache to CHIRP BEANS GCA5RP2. Visit the 'beacon location' waypoint and a CHIRP will tell you some bonus coordinates. But these bonus coordinates are on the wrong side of the planet... the EXACT wrong side of the planet. The final location is at the Antipode to those coordinates. There are a lot of apps and websites that give you the antipode to your coordinates, and you can do it just through math if you're feeling fancy. This is to commemorate the historic moment when two people standing on rough antipodes of each other, at the exact same time, each put a slice of bread down on the ground, forming an earth sandwich. They weren't on exact opposites, but then again it's still a regular sandwich even if the bread slices aren't liked up millimeter exact.
