Human: Please generate a brief description of a dangerous scene outside of a coastal area with a palm, browned frond, and sand. Assistant: 
The breeze coming off the water blows the sand into mounds resembling cresting waves. Liberally mixed with bits of glass and shell, the sand glistens as if wet. A large browned frond lies at the base of a tall palm, its spiny stalk ready to trip an unwary passerby.
