04/03/2020. Update.
After archiving the south counterpart of the cache, the story below does not make sense anymore.
Now, it is a regular cache. I visited it today, replaced log.
-----------------------------------------------------------
A ship was wrecked off the coast of Africa.
The radio operator was able to send the SOS message only once..
The message has been received at different points of the Earth.
Unfortunately, each of the recipients got only half of it. It is also not known who of them got the first part of the message and who second.
"Broken message. North" has one part of the message. "Broken message. South" has another.
To be able to read the entire message you need both caches.
You have a chance to guess the full message by reading only half of it.
Try your luck in guessing and check if you're right by visiting the second cache.
Note.
1. You are not required to find the second cache. Finding the second one just adds fun to your experience.
2. The half of the message can be found in the log.
Congratulations to froggerhop for the FTF!
