On July 24, 1947, the Hotel Mt. Lassen was destroyed by fire. The fire was so intense that it completely gutted the structure. Fred Abbay, the owner of the hotel, estimated the loss of the hotel, its contents and the businesses housed there at $700,000. Initially, it was uncertain what would become of the property. A structual engineer was brought in to ascertain whether the exterior walls were sound. It was determined that they were. In the fall, Abbay announced his intention to rebuild the hotel, utilizing the existing walls. The rebuilt Hotel Mt. Lassen opened its doors to the public on May 21, 1949.
In 2019, the big question, since the place has been closed for nearly a decade, will it ever re-open?
