11. During this work he discovered �lgruben rock glacier and the rock glacier north of Krummgampenspitze. 12. Fossil remains of rock glaciers have been found on the southeastern flank at altitudes of. 13. On Nocarane, three different stages of rock glacier activity have been foun on the southern flank. 14. Beneath rock walls, possibly active rock glaciers are found at altitudes at Nocarane and on Chachani. 15. In addition, lobate debris aprons can show surface lineations just as rock glaciers on the Earth. 16. At first they appeared to resemble rock glaciers on Earth, but scientists could not be sure. 17. Additional forms of glacial deposits, which extend down to above sea level, include rock glaciers and limestone pavements. 18. If a retreating glacier gains enough debris, it may become a rock glacier , like the Timpanogos Glacier in Utah. 19. The presence of a rock glacier in the area points strongly to the glacial origins of this chain of lakes. 20. A large rock glacier ( " Blockgletscher " ) is located east of D�sener See, with a permafrost depth of up to.
