Alderängarna Nature Reserve

Alderängarna's nature reserve is just outside Mora towards Älvdalen. Here a labyrinthine area of ​​meadows and waterways awaits with unusual animals and plants. A nine kilometer long hiking trail runs through the area.

Geology Alderängarna are part of the large Mora field, which is composed of several different sand deposits. Here, from the ice age to the present, two generations of rivers have left their mark in the landscape. One of the country's largest glacier deltas has been formed where Österdalälven today flows into the Siljansringen, west of Mora. When the ice receded 10,000 years ago, an ice river ran along the valley of Österdalälven, which ended up in a bay in the Siljans area's ring-shaped crater. Huge amounts of sand were deposited and formed one of Sweden's largest iceberg deltas. As soon as the delta was laid dry through the land elevation, the sandy surface was transformed by the wind into a rolling dune field, Scandinavia's largest. Österdalälven has since gradually cut itself deep through the delta and today there is a magnificent riverbed with today's smaller delta, wide river planes, terraces and arch-shaped slopes. Practical Information: On the site there is a resting place, outhouse, fire place as well as wind shelter.
