Title	Consolidated Rock Products digging in a rocky trench, 1929
Description	Photograph of Consolidated Rock Products digging in a rocky trench, 1929. In the background at center, a large rectangular base with a metallic structural-extension connected to a ramp is visible. Adjacent to the structure on the left, a smaller building with a pitched roof can be seen. Two utility poles are visible next to this small building. Two cables can be seen running from the smaller building to the top of the metallic structure at center. The two cables are seen wrapping around a circular pulley at the top of the large conveyer ramp. At the center of the ramp, a wheeled box can be seen supported by several cables connected to the pulley at the top of the ramp. Several metallic bars and rails are visible beneath the body of the ramp. To the right of the large conveyer ramp, two additional ramps can be seen near the edge of the dirt cliff. These wide ramps connect to railroad tracks seen against the cliff in the background. The railroad tracks can be seen winding from the cliff in the background to the foreground at center. Two railroad cars can be seen sitting on the tracks at center. A metallic, pivoting arm is connected to the car on the right, and part of the arm can be seen lodged into the nearby rocky cliff. In the background to the right, a railroad track is visible curving to the right. Another railroad car with an extendible arm can be seen against a sandy cliff. In the extreme background, utility poles are visible near lines of trees, while the silhouette of a mountain range can be seen. In the extreme foreground, two latched briefcases with handles are seen amid groups of large rocks. Back of the photoprint reads: "Baldwin Park plant and deposit of Consolidated Rock Products Company, 1929".
