Craft a 300 DPI coloring book page showcasing the wildlife of the Himalayan foothills. Envision snow leopards stalking their prey, yaks grazing on sparse vegetation, and eagles soaring against the backdrop of towering peaks. Use only clear black outlines to bring this high-altitude scene to life, ensuring ample white spaces for artists to color. Remember, no shading at all; the outlines alone should transport the artist to these lofty heights."
