I took this on my way home this morning, this is from ~10 miles away so it's a big fire. The grade is steep there so the fire is going to climb quickly. It would be suicide for a ground crew to pin themselves up against the Flatirons to save this forest so I imagine all the great trails in this area are going to suck for a few years. Also, due to the steep pitch of the terrain, it's now very vulnerable to erosion (mudslides). Just my 2 cents from a glance.
I went to a wildland fire class a few weeks ago and spent 2 hours learning about how wild fires spread and how to save your house if a fire is coming. Fire mitigation. I also learned that the mountain fire district will drive through a neighborhood and rate each house based on it's vulnerability (IE: owner laziness or lack of caring in regards to fire proofing their land like clearing trees from near the house or cutting the tall grasses. A wood shingle roof means you're f**ked). They then place either a red, yellow or green distinction on your house. If a fire hits and your house is "red" then they drive right on by. If it's green then they will make an attempt to save your house if it's in danger. Ruthless but necessary.
