The Hermiston fireworks display on the 4th of July set the south side of the Hermiston Butte on fire. The grass on the north side of the butte was burned off by the fire department as a precaution before the show because they were launching the show from the top. The un-burned side caught fire shortly after the fireworks display started according to news reports. That fire was fought by multiple trucks from Umatilla County Fire District and had most of the fires under control by 10:45 pm.
