There are taiga forests of conifers, mostly larch , in the slopes of the mountains up to 900 meters (3,000 ft) to 1,100 meters (3,600 ft), often mixed with Siberian pine . At higher altitudes these give way to thickets of dwarf Siberian pine up to

According to a 2013 study, the range contains 34 glaciers . With the exception of some tropical glaciers, they are the most isolated glaciers the world, over 1,200 kilometers (750 mi) away from any other glacier. The glaciers are small, at most 2.1 kilometers (1.3 mi) in length. The area experiences
