Geocache Description:

Since I regularly work with these beautiful and amazing creatures, I would like to give you a small riddle about our local cetaceans.

All the following species have been recorded here on the Azores. Worldwide we have around 90 different species of cetaceans, so as you can see we have almost one third of the worldwide occurring species here! What a hotspot! :-)



Maybe some of you already know the common names of these guys. However, that would be too easy - so in order to receive the coordinates, you need to figure out the scientific names and form them into numbers. Nevertheless, there is a trick, because these numbers must be in between 0 - 9 for each species. Do you have an idea? Great, then let's go!

Afterwards, you need to multiply these numbers. Multiply all numbers for species 1-14 and divide it by the answer to the ultimate question of life, universe and everything and then add 98.324. Here you have the north coordinate!

For the west coordinate just multiply all numbers for species 15-28 and substract 6.629.478. Easy, hm? 

If you did everything correctly, you should be ready to go! :-)


You will have to look for a small petling.
