Minecraft wiki entry for Mountains, associated text: The grove creates a forest of spruce trees on the sides of a mountain, reminiscent of a snowy taiga but the surface is covered with snow layers, snow blocks, dirt and a lot of powder snow instead of grass blocks. Rabbits, wolves and red foxes can spawn in this biome. This biome generates in high altitudes beneath the peaks and on hilltops next to forested biomes such as dark forests and taigas, and can generate as a large biome at lower altitudes if next to snowy biomes.
