俺已经更新了新的博客，希望对你有点帮助，冰川名字叫Sólheimajökull ，参考这里，

A short distance east of Skógar, Rtes. 221 and 222 provide the easiest Ring Road access to Mýrdalsjökull, the country's fourth-largest glacier. Sólheimajökull, a projectile of Mýrdalsjökull, just 5km (3 miles) from the Ring Road via Route 221, is a worthwhile diversion if you are not bound for greater glories farther east at Skaftafell and Jökulsárlón. Sólheimajökull is retreating up to 100m (328 ft.) every year, a vivid demonstration of the effects of global warming. Some visitors walk atop the glacier, but taking a tour is much safer. Watch out for quicksand at the glacier's edge.

如果你在冰岛能呆4天以上，看到北极光的可能性至少有80%，照相机最好要有长镜头，要是有摄影高手同行就太棒了！祝你玩得开心。
