Produce a detailed written description of a chilling geyser in the wilderness with black moss, steam vents, and rock.
assistant
Cascades of once-liquefied rock act like steps from a short stone rise to the east. Plumes of steam from that direction drift into the area and making it difficult to see. The only vegetation to be found is a simple black moss which hugs the rim of some seething steam vents. Scalding water occasionally bursts from these vents and releases a noxious, gaseous odor.
