Last November, when the Woolsey Fire tore through Malibu Creek State Park in California, the area where outdoor scenes for M*A*S*H were filmed was burned but not destroyed as previously reported. According to a post at the Reddit M*A*S*H community by someone who hiked out to the site last month, “There was charred trees and bushes all around the site, and the helipad looks like it was completely on fire at one point, but the picnic benches and sign post survived.”
The California Department of Parks and Recreation re-opened portions of Malibu Creek State Park on December 18th, 2018. The campground is still closed. Although the M*A*S*H filming location survived relatively intact, a number of structures in the park were destroyed, including “employee residences, the historic Sepulveda Adobe, Red House, Hope Ranch also known as the White Oak Barn (including historic Adamson rowboats) and Reagan Ranch.”
The official website for the park has the following notice: “Malibu Creek State Park was badly damaged in a November 2018 wildfire, but recovery has begun. Please tread lightly and exercise caution when visiting.
