On July 21, 1917, Harrison, Idaho, was a thriving mill town with a population of around 1,200. The next day, a devastating fire ignited at the Grant Lumber Company and rapidly consumed much of the town. Fueled by high winds, the blaze destroyed approximately 30 residences, sawmills, and the entire business district. The town's wooden structures, including sidewalks and buildings, were particularly vulnerable, leading to a swift and overwhelming destruction.
In the aftermath, many residents and business owners faced profound loss. Some chose not to rebuild, while others, determined to restore the town's spirit, constructed new fire-resistant brick buildings. By 1918, six such brick structures lined the main street, forming what is now known as the Harrison Commercial Historic District. Despite these efforts, the town never fully regained its former size or prominence. However, the resilience and determination of its people ensured that Harrison endured, preserving its rich history and community spirit.
