21. One of the most notable features of the park is the presence of large talus slopes on three sides of the lake. 22. The garden is situated on a high ridge south of Mont Blanc, and contains a rockery, alpine pasture, talus slopes , and wetlands. 23. The fern thrives in thin serpentine soils on sunny, disturbed habitats such as roadcuts and talus slopes , in dunite and other ultramafic rocks. 24. The algific talus slope habitat that harbors the snail is a landscape cooled by air and water emerging from masses of subterranean ice. 25. After four hours of half-crawling and half-climbing uphill, the trail turns into a talus slope of massive rocks, and Kendall takes the lead. 26. It grows on talus slopes near the tree line in the mountains, 3000 3400 meters ( 10, 000-11, 300 feet ) above sea level. 27. In situations where the slope angles are steeper than 25?. gravity tends to move the boulders downhill to form scree or talus slopes . 28. This action has left many talus slopes at the base of Moosic Mountains, and the soils often contain large boulders that make excavation difficult. 29. Both ways the route will start in low birch forest and gradually enter long talus slopes and plains with many snow patches in the summer. 30. The summit can be reached without equipment if the conditions are good and there is very little snow on the talus slopes on the southwest face.
