In 1968 Troh’s Nest was built on the east side of Scouter’s Mountain and was the
third and last of Henry Troh’s Portland area airports. His home, pictured in the
in the foreground, was used to run a successful charter business from the
airport until his untimely passing at 57 from a brain tumor in 1968.
The airport was re-classified as public in 1977 and is known as Troh’s Memorial
Air Park / Happy Valley Airport Happy Valley, OR.
As of 2012, Happy Valley Airport is no longer depicted on Sectional Charts, but
continues to be listed in the FAA Airport/Facility Directory data as an active private airfield with 3 aircraft based on the field (2 single-engine, and 1 helicopter). The site
of Happy Valley Airport is located east of the intersection of Southeast Vrandenburg Road & Southeast Airport Road,
