Change History
Moderators will move threads from "Checker requests" into this forum after a while when it has been decided that the challenge checker isn't possible for one or another reason. The threads should not be moved right away. The challenge owner should have a chance to adjust his requirements if that helps.

Re: Challenge Terrestrial Caches below sea level
There is two FAQ items about elevation
http://project-gc.com/Home/FAQ#2384662308
http://project-gc.com/Home/FAQ#4179902386
My guess is that the information is from SRTM3 https://en.wikipedia.org/wiki/Shuttle_Radar_Topography_Mission
The data was collecter during https://en.wikipedia.org/wiki/STS-99 in 2000
So if it is a deep open-pit mine then you will get those elevations
edit: If you use historical images on google earth you will see the pit. 200 the eastern part was partially refilld but where the cache is is still a deep pit
