JOHN MARTIN DAM, Colo. – A contractor ropes team scales the nose pier on upstream side of dam, Nov. 8, 2022. Three-person ropes teams installed instrumentation cables and conduit up the face of the dam from borings in the lake, assisted by a dive team. The scaler’s shadow is enhanced by late afternoon sun.
