I’ve been out there before when I was in wildland fire with BLM, one of the issues with the Preserve is (and issue meaning making things more difficult, not that it’s a bad thing in general) there’s a very strict ban on vehicles going anywhere besides premade roads/trails.
That means that instead of like most fires in this type of fuel where engines can drive up and directly attack it, it’s a hiking game. And even then there is strict rules about what kind of damage you can do to the area. In any other area this would a straight forward, put dozer line in, have crews start burning, and engines start mobile attacking areas they can get to. That’s why seeing fires like this sucks, because I know the crew (if they haven’t all left yet) from the Mojave National Preserve, and I know they’d want to do more to stop it.
