Original structures

Today, only one original Camp Abbot building remains. The officers' mess hall was built in 1943 by the
Army Corps of Engineers under the direction of Captain John V. Banks. It remains at its original location as Sunriver Resort's ''Great Hall'', used for large conferences and special events, such as banquets and weddings.
The historic Great Hall is an impressive log structure measuring , constructed with native stone and logs cut near the building site. It has a high ceiling with exposed beams, a large stone fireplace, and a balcony overlooking the main floor. There are also small side rooms including an intimate fireside room and a number of conference rooms. In 1993, Sunriver Resort completed a major renovation of the historic Great Hall, and it is now a modern facility with unique architectural character.
The only other major Camp Abbot structure to survive for an extended period was the General Patch Bridge which was constructed in 1943 by Army engineers during the
Oregon Maneuver. The Oregon Maneuver was the largest military field exercise ever conducted in the
