| Gloppedalsura Magma Geopark Stavanger Norway. Gloppedalsura consists of avalanche boulders that are piled on top of an end moraine. 10,000 years ago the ice sheet that covered the area, melted away. For a period of time the massive end moraine dammed the Hunnedal river`s former course, towards Veen and VikesÃÂ¥, and formed a lake in Byrkjedalsgryta. The terraces in Byrkjedal at 240 metres altitude are evidence of this moraine-dammed lake. The annual cycle of frost and expanding ice broke free a vast number of boulders and rocks and sent them tumbling down the southern mountainside. This debris settled as a 100-metre thick scree on top of the moraine. Hunnedal river and the lake in Byrkjedalsgryta were forced to find a new outlet; the water burrowed a gully from Byrkjedal towards Gilja - Giljajuvet |
