The fire near Kennewick by Clodfelter and Hildebrand burned about 100 acres. Crews say it appears this one was intentionally set.
The fire near the old race track in West Richland off SR-224/Mayo Loop Road burned 10-15 acres. A 20 year old was off-roading and a tumbleweed got caught under car which ignited and caused the fire. Part of the land is owned by the Department of Natural Resources.
