Go to the cache that is missing scroll to the bottom and tap "Report the a problem with the cache" and choose either "needs maintenance" or "needs archive".
You don't really wanna hide them when you visit then archive them when you leave because it takes effort when hiding a geocache. It's best to hide geocaches in your area.
There has to be a way to maintain the cache. So for example if the cache gets broken or missing and it needs to be replaced and your somewhere else then you can't really handle it. If you have a family member or freind that's in the area of the cache and can maintain it then thats when you can hide one.
Hi! So I have a geocache and I used the compass app to get the coordinates, but then later on I realized that it shows my geocache is somewhere else then its supposed to be. How can I get the exact coordinates?
Mark a DNF on it, and if you really want to find that geocache message the owner for a clue, and if you are for sure it's not there then tell the owner it might not be there anymore.
