The first field school was offered in 1995 at the Peter French Round Barn (built 1884) in Harney County in Eastern Oregon.

The 1996 field school was held in Port Orford on the Oregon Coast and centered on the Cape Blanco Lighthouse (1870) and the Hughes House (1898).

The 1998 field school took place at Fort Stevens State Park, Oregon. Preservation work included the Guard House and the Officer's Quarters.

In 1999, the field school traveled to Port Townsend, WA. Participants rehabilitated military structures at Fort Worden.

An historic Queen Anne house in Eugene, Oregon was chosen as the site of the 2000 field school.The house was built in 1888, employing balloon frame construction.  Students had the opportunity to restore windows, refinish iron cresting, and work on other late 19th Century details.

During the Summer of 2001, the field school focused attention on the Wilkins Ranch House located at Point Reyes National Seashore, CA. The house was built (c.1870) as part of a ranch complex for the historic dairy farming industry of the Point Reyes Peninsula.

In 2002, two projects kept the field school busy on Whidbey Island. Participants replaced logs on the block house, reroofed, and made structural changes to the Ebey House and learned about window restorations.

In 2003, the field school moved to the oldest continuously-operating water-powered mill in Oregon, the historic Thompson's Flouring Mill in Shedd.   The students' work included: archaeology, timber frame construction and repair, wood window repair, and a study of water-powered engineering.

The Railroad Ranch in Idaho's Harriman State Park was the site of the 2004 field school.  Students stabilized a log sheep barn with work on its roof, windows, and chinking.

And in 2005, students reconstructed a Civilian Conservation Corps-era (CCC) kitchen shelter at the Jessie M. Honeyman Memorial State Park on the coast of Oregon.
