The Waldo Canyon fire in Colorado Springs is not the largest but definitely the most destructive, with ~350 homes destroyed. We are fortunate to not have to deal with this, but many do. This blog shows what it has been like for them.
We need to remember them in our prayers.

The largest fire ever in my neck of the woods was a little over 1800 acres in 1980. We thought that was bad.
