Airplane Crash Memorial

on Jamacha Ridge




Cuyamaca Plane Crash Memorial Site

Monument Trail
Descanso, CA 91916
32.908702, -116.580885

Location: The memorial is off Highway 79, and is accessible from either the Sweetwater Bridge parking area or Green Valley campground.  The hike to see the monument is almost entirely uphill with over 800 feet of altitude.

Distance: About 4.5-miles out-and-back on the same trail, or about a 5.3-mile loop if continuing north on the Monument Trail

Difficulty: Moderately Strenuous

Before you go: It is highly recommended that you pick up a map from the ranger's station at the Green Valley campground and have them mark where the trailhead is.  

**No dogs allowed**

Trailhead: Off Highway 79, park in the large Sweetwater Trailhead parking area in Cuyamaca Rancho State Park, just north of the Green Valley campground and south of the visitors center.  From this parking area, walk north across the bridge over Sweetwater River on Highway 79 to start on the West Side Trail on the west side of the road.


Located 800 feet above a trailhead near Green Valley Falls lays "one of the most sought after crash sites in U.S. military history.”  The memorial site is small, consisting of a burned V-12 cylinder aircraft engine mounted on a stone & concrete pedestal and a plaque attached to the pedestal dedicated to U.S. Army pilot First Lieutenant Charles F. Webber and U.S. Cavalry Colonel Francis C. Marshall.  The plaque reads "Who fell on this spot on December 7, 1922.”

The backstory goes that on December 7th, 1923 two military officers had left Rockwell Field, North Island in a  twin-seat Army DeHaviland DH4B model biplane one morning to inspect cavalry posts throughout the Southwest.  26-year-old pilot First Lieutenant Charles F. Webber was navigating the plane with 55-year-old Colonel Francis C. Marshall in the forward passenger seat.

Within two weeks they had logged almost 4,000 miles of exploring and mapping potential air routes.  This was arguably the most historic use of DH4Bs, the first successful aerial refueling from their plane to that of fellow pilots’ Lieutenants Lowell H. Smith and John Paul Richter beneath them.  There were many known dangers involved in this flight as both were aware, especially flying in an outdated aircraft over the rugged mountain and desert route between San Diego and Fort Huachuca.  Fog and an inability for the failing engine to climb high enough to avoid the trees on this ridge were other major contributors.

Many pilots attempted to locate the crash site when the two failed to reach their destination that day.  By December 17th, their search had grown to the largest combined air and ground search in U.S. military history during peacetime.  

It wasn't until May 4th, 1923, almost a year later, that the wreckage and pilots were discovered.  A local ranger named George W. McCain was riding on horseback along Japacha Ridge when he discovered them.  A memorial was soon dedicated to them by the Civilian Conservation Corps works.  

The trail starts on the West Side Trail where some fine old oaks and pines still thrive.  After 0.6 mile, it intersects with the Monument Trail, when the elevation gain really begins.  You can make a 5.3-mile loop hike by continuing north on Monument Trail from the little spur trail to the actual monument. This trail becomes West Mesa Trail, then intersects on the right with the Japacha Fire Road to take you back to your starting point.  Or you can climb to the monument and retrace your way back for about a 4.5-mile round-trip.

Personal Experience:  We went in late spring when the wildflowers were in full bloom.  It was such a beautiful hike.  I would recommend going in spring or autumn for optimal weather.  I made it my personal goal to take a photo of every different type of flower I came across. :P  The hike was not too bad at all.  We were finished with the entire hike in maybe an hour and a half.  That was with taking many photo stops.  The views are fantastic.
