Rock folded by a glacier (Lahka national park)

by Ivana Richterova, Charles University in Prague, Prague, Czech Republic

Lahka national Park is a magnificent example of rocks formed by a glacier mass. Curved detail smaller then one centimeter can be found here as well as several meter wide oblong pyramids in the old glacier river bed close to Glomfjord. Folding is well apparent due to different erosion speeds of particular layers of the sediment rock.
