Three men operate a large jackhammer against a rocky cliff face

Three men operate a large jackhammer against a rocky cliff face. The shirtless man to the left wears dirty jeans and a cap, back covered in dust. The central figure, also covered in dust, uses both hands to guide the drill. A third man wearing a striped shirt, dust-covered pants, a cap, and a yellow face covering holds the drill steady. All three men appear to be barefoot. Dust and debris surround the base of the jackhammer.
