Found this one from cache Paska-Avenue ( https://coord.info/GC7HP9T ) in Karstula. It was next to a vulcanic looking stone, not sure if it belonged to it because they were separate pieces but looked like it so I attached stone to it. 😅
Anyway, I'm going to place cache tomorrow at Salamajärvi National Park and I will place this traveler there too to be finded there. Hopefully cache will be published soon. 😊
