A glacial erratic is a piece of rock that differs from the size and type of rock native to the area in which it rests. "Erratics" take their name from the latin word "errere", and are carried by glacial ice, often over distances of hundreds of kilometres. Erratics can range in size from pebbles to large boulders. They were dropped for example on a glacier by landslides and then the glacier carried the rocks with it. When it melted the rocks were left in their current position.
This special glacial erratic is located above the highest coastline, in an area that was not sea after the ice age. It’s lying on top of a hill (named by the rock, Storstenshöjden), which is the highest in the surroundings. Either the glacier worked as a dozer blade on a huge excavator and slides the rock in front of it in north-south direction. The glacier reached the top of the hill but stopped there and the rock stopped exactly at the edge before it was falling down. When the ice melted the rock was left in its position. Or the glacier carried the rock with it and when it melted the rock fell down and was left accidentally at its place on top of this hill.
To log this earthcache as found you have to:
- Measure the circumference of the boulder (at its thickest point) and mail us the answer.
- Please upload a photo with you and your GPS in front of the boulder. (A photo is no longer required for the log, but it would be nice)
Logs without correct answer-mails will be deleted. You don´t have to wait for permission. We´ll contact you, if there is a problem.
Don´t post the answers in your log.
