    It’s been disappearing from the US for decades. The last remnants were in unpopulated areas of the mountain and desert southwest. I do’t think there is any left , unless is was an area accidentally skipped when the regulations changing various Class Gs to Es were written

    Not “quite” all gone, Mark, but really close in the CONUS.

    Airport “13Q” in western NM has some around it, and there might be one or two others. There used to be a little sliver near the Grand Canyon, up until a few months ago but it looks like that was removed as well.

    Now, go up into Alaska and you’ll find some still remaining. North and south of PAPT, for example, and then some straight north of PAFM. A few other areas.

    Well I got interested and looked around, and found just one more, SE of MRF, Marfa, TX, on the border with Mexico.

    So as far as I can tell, here is the complete list of 14,500 ft Class G airspace in the CONUS:

    Around 13Q (NM)
    SE of MRF (TX)

    All the rest are in Alaska.

    It was only about 4 or 5 years ago when you could follow a rough line of 14,500 Class G starting in North Dakota and ending in NM (with lots of breaks and zig zags on the way). There was a lot more of it just that recently. Now, it’s essentially just an academic curiosity for most pilots.

    Look on the Low Altitude enroute charts for a tan stain on the white areas. This is used to indicate that the G airspace does not stop at 1200 AGL.This makes it relatively easy to spot remaining “high” class G airspace.
