  • Hell I’m on dyerville loop and it’s hazardous.

  • What’s a clean air shelter?

  • Is it healthy to hike the Trinity Alps, more specifically, Boulder lakes trail?

    • I would avoid it. That is not too far from Weaverville, and I would be uncomfortable being away from cell service that close to a wildfire. I would be afraid of getting trapped. If you really want to go, I would call up the Weaverville ranger station and ask. They may not even be giving out permits for that area if the air quality is bad.

  • 5 pm — here in Lake Co., the smoke is so thick you can’t see across the lake; in fact, you can hardly see the lake itself from a short distance. Local source,, reports that the source of the smoke is primarily from the Helena fire in Trinity County, as well as a current of smoke spreading over the region from as far away as Montana. The fire station on Mt. Konocti (4000+ feet) was closed because of lack of visibility earlier today. Very creepy. Heading up your way on Saturday for long-awaited gathering of old friends, and now reading about fire between New Harris & Richardson Grove, plus fire on Spy Rock Road. Lots more hot dry weather coming, too…. Thank you, Kym & correspondents, for keeping us informed (way better than CalFire website!) Keep safe everyone, and don’t play with matches.

  • Is it safe to go camping in Denny

  • Given the density of the smoke in central and southern Humboldt…
    We could use a few clean air shelters…

  • Yes my name is lucky I live in Redding it is very bad I would do anything to have a clean place to go until the smoke lifts I have asthma I can’t even have my AC unit on I volunteer at the Good News Rescue Mission considering going there for a couple days
