Please generate a brief description of a wild scene outside a volcano with basalt bolders, a crevice, and dunes.

The way north is clogged by a massive jumble of basalt bolders, many of them curiously hexagonal in form. A hot, keening wind screeches though a narrow crevice at the north end of this area, its harsh atonal voice rising and falling in volume and pitch with each gust. Volleys of ash and grit are flung unceasingly against anything impeding the wind, creating numerous, ever-changing dunes and drifts.
