Human: Please generate a detailed written description of a chilling scene on a glacier with boulders and ice. Assistant: 
A pile of boulders rests uneasily at the top of the mountain's cap, feathered in elaborate ice crystal patterns growing over their surfaces. Gritty snow crusted over with frozen melt forms a thick layer over the granite rock below, making the few bare spots seem dark by comparison. Shifting ice from the massive glacier occasionally gives off a sharp crack that pierces the air, breaking the lonely silence of the frozen mountaintop.
