In the middle of a vast, arid plain, a large sinkhole has opened up, swallowing a horse and creating a cavernous pit. The horse stands at the edge of the sinkhole, looking out at the desolate landscape. The sinkhole is surrounded by a sheer rock face, and the ground is covered in loose rocks and debris. The sky is clear and blue, and the sun shines brightly, casting long shadows across the scene.
