However, the related adventure lab is very close.
This is a bonus cache for the "Looking for Ducks?" Adventure Lab. Completing the Adventure Lab will provide you with the coordinates.
The Adventure Lab can be found at: https://adventurelab.page.link/wLry.
If you are looking for ducks, you have come to the right place.
I love that South Dakota has many species of ducks that call our state home, at least for parts of the year.
The adventure lab related to this bonus cache will let you see 6 different duck species up close and learn more about each of them. You will need to scan the QR codes near each duck to learn more about them in order to answer the questions (or you will have to have knowledge of ducks).
They are all travel bugs, so you can log them as well! This adventure lab is located in GeoquackerO> and Asgoroth's yard.
You have permission to visit the adventure lab during daylight hours only, however, the bonus cache container is in a public place that is available at all times.
