Stones, Rocks and Boulders





Two thousand years ago, around 1 B.C. to 1 A.D., the archipeligo on the western side of Finland that we have been visiting and boating around was under water due to the compression of ice glaciers on the land from the last ice age. Since then, the land has risen about 1 cm per year and has created the archipeligo with Jakobstad and Larsmo in the group. And the land is still rising.

Not only have the glaciers compressed the land, they also scraped across the land bringing with them large rocks and boulders and stones, but also breaking up the rockbed of granite that was already here. (Mom and I keep joking about the granite countertops we could create with these rocks.)

Whenever someone tries to build any type of structure or farm the land, they must decide to build over the rocks and boulders or to move them. Look and the pictures and try to imagine moving these rocks. The pictures do not do the up close justice. The stones, rocks, and boulders are everywhere and are huge!

There is some great information about this at an island exhibit called 'Terra Mare' on the island of Kopmanholmen.
