And more fun .......

I created a challenge two days ago, just to test the system if nothing else. Afterwards, I realised that there were issues which make the challenge difficult to complete, although on the surface of it it doesn't appear that hard.

This one -

It was designed to reward people who get out there. The problem is of course finding out the altitudes.
I would be quite happy if people could vote it out of existence!

If I re-create it it will be with a list.

Finding a list of elevations (altitudes) is an interesting problem
When you run the FindGenStats macro in GSAK, it somehow goes away and extracts the elevations for caches you have found, from a geo database somewhere.
But how do you do this for caches you own, or caches which you haven't found?
It would probably take a while as there are external database calls involved, but theoretically it should be possible to butcher this macro to do the job for all caches in a filter.

30m resolution

Don't blame me if they block your IP address.

If that doesn't respond, try the 90m resolution.

Or try the Google Maps API.

There's a stand-alone GSAK macro that will find the elevations.
