Expansion of OSU-Cascades, the University’s branch campus in Central Oregon, continues in a former pumice mine. The camera is positioned in at the east edge of a bowl that was formerly a productive pumice mine, looking west toward the deepest portion of the mine, where the bottom is approximately 100 ft. below the surrounding land. During the first phase of reclamation work, crews removed fill material in the mine, processed it and replaced it to create a structurally consistent material able to support buildings. Sheer cuts on the sides of the mine were re-sloped to improve access and safety for the new campus and yield fill material to raise the floor of the mine up to 40 ft. Additionally, remediation of an adjacent demolition waste landfill – also owned by the University – yields clean soil and rock to be used as fill. Edward J Ray Hall is prominent in the left of the frame. It opened in 2021 and is named for OSU’s President Emeritus who was instrumental in the establishment of OSU-Cascades. A new Student Success Center will be built in the open area in the center of the frame, with opening planned in Fall 2024. The small white building at the right houses part of a geothermal heating and cooling system that makes the OSU-Cascades campus one of the most energy efficient in the country. On a clear day several Cascades peaks are visible on the skyline, with Mt. Bachelor most noticeable near the center of the frame.
