View of the excavation of Arroyo Seco Drive south of Avenue Forty-Nine, March 6, 1934

A deep, wide ditch is at center and dozens of workers are excavating at the bottom. A narrow stream runs along the bottom of the ditch at left.

Crude wooden planks lead from the top of the ditch to the bottom. Several buildings can be seen in the distance at left, while a copse of tall trees is visible at right.
