The idea for this coin was to make a rather simple design and turn it to get different sceneries: a forest, a field, a campfire and the sea. On top of the sceneries are prints of different petroglyphs from my area. The backside is from a gilded clasp fro the 8th century found of Gotland, showing characteristic animal ornaments.
This version, "Stormy weather" shows old shipson a stormy sea. The ship carvings are known as "Lingaskeppen" and is far older than the other thna the viking carvings, They are at least 2500 years old but can be even older, they are from the period 1800- 500 BC.
There is no cache pointing out the carving, it can be found at N59 04.279 E17 35.076 but you have to cross a field. There is a modern intepretation of the ships in a roundabout nearby, and those ships have a cache - "Båtar på torra land" (GC371E7)
