The Stonetalon Mountains, aka Stonetalons, are a range of peaks that lie west of the Barrens, south of Ashenvale, and north of Desolace. The mountains are traditionally the homeland of the harpies, but their numbers have dwindled as the bird-women spread east and south. Stonetalon Peak, the largest mountain in the range, has long been a sacred place for both the night elves and tauren. The night elves maintain a barrow and a glade at the top, where they commune regularly with the spirits of nature. The mountains further south are less forested, although some sparse evergreens grow in certain spots, particularly the Greatwood Vale. The Venture Trading Company have put a heavy toll on the land, cutting down almost all the trees in Windshear Crag and filling the air with soot, spoiling the area's water with oil and waste much to the fury of the orcs and tauren. The tauren have a holding in the centrally located Sun Rock Retreat and the Darkspear trolls have a settlement further south at Malaka'jin. The mountains are also home to kobolds, spiders, and wyverns, while Charred Vale holds several especially dangerous kinds of beasts and elementals.

The Stonetalon Mountains were once a low set of hills giving a gentle view to the ocean waves in the west. The Sundering that tore apart the world drove great sandstone cliffs and mountain peaks high in the air. Water from the eastern coast poured into the newly created chasms and gorges. With the aid of erosion from the Blackwolf River, the Stonetalon Mountains have expanded into a vast network of canyons and cliff openings that invites adventurers and beasts alike to explore the virgin lands. The Stonetalons rise in central Kalimdor, south of Ashenvale Forest and north of Desolace. The mountain range feeds into the bleak expanse of the Barrens to the east. The atmosphere of the Stonetalon Mountains can best be described as extreme. At the lower elevations it is windy, hot, and dry. It is a harsh place where food cannot grow and flash floods are commonplace in the early summer months.

Moisture from the ocean builds up into huge rain clouds, but the towering peaks are too high for the clouds to pass inland. They crash against the mountains’ western side and pour massive sheets of water upon the slopes to run through narrow canyons and back into the ocean or into a valley to dry up in a marshy sink. When the weather turns to rain, the ground grows slick and gray. Walking on a slope or a cliff in the rain is treacherous — water seeps through the sandstone and threatens to send even careful travelers plummeting to their deaths. Oftentimes, when the clouds expel all their moisture, hot winds push them farther up the slope, surrounding the Stonetalon Peak in a shroud of thundering mist. An immediate feature any visitor notices — aside from the sheer cliffs and deep crevasses - is the constantly blowing wind. Sometimes a gentle breeze carries fresh air in from the ocean and other times a violent gale stirs up vicious dust devils or brings a storm in from the western mountains. The rugged mountains are home to many wild beasts and only a few civilized habitations. Hippogryphs roost near Mirkfallon Lake in cave complexes high on the slopes. Their nests are defended by large bramble hedgerows, making access nearly impossible without flying. Other creatures found throughout the mountains are striders, hyenas, kobolds, swoops, crag panthers, and even rock elementals and the rare sabertooth cat.

Further up the Stonetalon Peak, on its eastern side, are the chaotic lands of the wyverns and drakes. These ancient “flying lizards” have long been rivals for supremacy of the skies. Every once in a while, when other races threaten to interfere, the two will set aside their differences long enough to deal with the interlopers. Agents of the goblin-run Venture Company have also been sighted in the area, searching for potential tracts to deforest and streams of precious ore to plunder with their mining machines. The mountains are known for their Ill Winds. The winds whip through the Stonetalon Mountains with great force, slowing travelers' progress and throwing up clouds of grit and dust that can confuse the best sense of direction. Small and lightly built individuals have even been flung off a mountainside by a particularly forceful gust. The wind in Stonetalons seldom drops below moderate even on a calm day and can change from a steady breeze to a brutal windstorm without warning.
