Photograph showing the exterior of the Cazadero power station taken from across the Clackamas River. Four large pipes run uphill from the building. Previously burnt trees can be seen in the background.

Photograph showing construction progress of the powerhouse at Cazadero Dam/Station G, taken from a high angle looking downhill. The foundation can be seen on the near side of the river, with multiple men working. Across the river, a dirt hillside with fallen trees and stumps can be seen.

Photograph, taken from across the river, of the Cazadero powerhouse/Station G. Part of the roof is incomplete, and three pipes run from the building up the hill. A stairway next to the pipes goes from the building to the top of the hill.

Photograph taken from a high angle of penstock units at Cazadero Dam/Station G. The pipes can be seen running downhill towards the in-progress powerhouse, with numerous workers.

Photograph showing construction progress on the intake penstocks at the Cazadero Dam/Station G. Workers are visible in the center of the frame, and five large pipes are seen on the right. Construction debris can be seen throughout the image.

Photograph showing small wooden building with piles of cut lumber in front of a steep logged hillside. On the right side of the frame, the Clackamas River, or Oak Grove Fork can be seen, and snow is on the ground throughout the image. Written on the negative is “E301.09-O-369.”
