Human: Please write a short description of a mystical scene outside of a wilderness area with columnar basalt and a geyser. Assistant: 
The trail stops at the foot of a ridge formed of columnar basalt. Rectangular fingers of stone reach up toward the sky like square tubes of a primitive pipe organ, their dark surfaces tinged in places with bright sienna. Crevices in the stone make climbing the ridge possible, however easier trails lead off in other directions.
