It's been quite a year. We had one 2020 fire that jumped the continental divide, was burning in the tundra on the way over, which I believe is a first on both counts.
There's also some consideration about two fires that began in Boulder County in mid-October, both in same neighborhood, with no apparent means of ignition, and people wonder if embers from a fire west of the divide could have jumped and started these two. The first one (Calwood Fire) began at a moment when we had sustained 50 mph winds from the west. That would have required a 30 mile travel thru the sky. The greatest documented ember travel before was 18 miles (in Australia). My first reaction would be to discount a 30 mile ember ignition, but we are in unprecedented times so who knows.
