Exterior of a sand and gravel plant, ca.1928

Photograph of exterior of a sand and gravel plant, ca.1928. To the left, a large partially-formed building can be seen. Five large entrances can be seen at the base of the building. Numerous panels and exposed support beams can be seen on the exterior of the building. To the left of the base, a wheeled machine holding a metallic crane arm extends towards the building. As the building grows in height, only the portion near the right of the building grows vertically. At this top section of the building, a small structure with two visible windows can be seen. Near the base of the building to the right, a large metallic conveyor is attached to a mall tower to the far right. The tower is supported by four large legs at its base. A metallic stairwell is attached to the side of the tower and curves around the structure. Visible support beams line all sides of the small tower. In the extreme background on the right, a small building with several windows lining its side can be seen. On the left, a tall building is also visible. A large mountain range can be seen in the far distance.

这张照片拍摄于约1928年，展示了一处砂石厂的外部景象。画面左侧可见一座尚未完工的大型建筑，其基座处设有五处大型出入口，建筑外立面遍布板材与裸露的承重梁。建筑基座的左侧，一台搭载金属吊臂的轮式机械正朝向该建筑延伸。随着建筑向上施工，仅其右侧区域仍在垂直加高；在该建筑的顶部区域，可见一座带有两扇外露窗户的小型附属结构。在右侧建筑基座附近，一台大型金属输送机连接至最右侧的小型塔楼。这座塔楼的基座由四根大型支柱支撑，塔身侧面设有金属楼梯，环绕塔楼结构蜿蜒延伸。这座小型塔楼的各侧面均排布有清晰可见的承重梁。画面最右侧的远景中，可见一座侧面排布有多扇窗户的小型建筑。画面左侧还可见一栋高层建筑，更远处则是连绵的大型山脉。
