    This afternoon my wife and I did the weirdest slot canyon that I have seen. It was near Baggs Wyoming of all places. We stumbled on it unintentionally and were just our for a leisurely walk. The canyon got deeper as we descended until it dropped into an underground tunnel. Past this there were some tight slot sections, several natural bridges and one long underground tunnel. It was barley doable without a headlamp and quite spooky. I could see light way up ahead and would have to feel the floor of the tunnel with my walking stick, afraid that there might be a hole or drop off.

    The walls of the canyon were very colorful and the rock was somewhat similar to the rock in Bryce Canyon. There were a few tricky down climbs and at the end the canyon had a drop that we could not down climb. We found a sketchy bypass some rock that wasn't exactly confidence building. After the bypass we were mostly home free. The canyon did drop into another underground section, but we skipped that part.

    Sadly, our camera died before we got to the slot. If the weather holds, I might go up there again Thanksgiving weekend and with fully charged camera. It should make for some interesting pictures. I have never seen a slot canyon like this one. We decided to call the canyon Maggie's Ghost Slot in honor of the colorful historical figure of Maggie Baggs, for which Baggs Wyoming is named for.

    It was an interesting day indeed.

    Although the camera died before we got to the slot, I did get a photo of the rock the slot is made of. In other parts the rock is orange or yellow.

    Is the rock rhyolite or tuff?

    Have to say I'm unfamiliar with the strange white coating on the rocks. We don't have that stuff here.

    The rock was mostly mudstone with sandstone forming the drops. Some of the bright colors come from volcanic ash.

    Maidstone?

    Google comes up with a 1970 movie and the name of a town in England.

    Looking for a little clarification.

    Also, unlikely to be volcanic ASH. More likely volcanic Tuff, which is welded ash, thus making it a form of rock.

    Mudstone. Since I'm in Mexico I only have the phone and it auto corrected to that.

    The canyon is in the Green River Formation:

    https://en.m.wikipedia.org/wiki/Green_River_Formation

    Intetestingly, much of the ash fell on a lake rather than solidified on land. Some of the layers around ash are full of fossil fish (though we didn't see or look for any).

    http://geology.com/articles/green-river-fossils/

    Since the ash layers are so thin (the ash came from Yellowstone and the San Juans), maybe it is too thin or unconsolidated to form tuff (?). Most geology reports I have seen only refer to tuff as existing farther south in the Green River Formation, such as around Piceance Creek, which is much farther south.

    Maybe there is tuff in this area though. I did find some reports mentioning tuff in other places not that far away. Anyway, I'll head there with a camera when I can.

    I'm much less familiar with the geology around Baggs Woming than in places like SE Utah, Zion, Grand Canyon,
    or the Wasatch.

    There are some short, shallow slots in the Green River Formation in some canyons in the Book Cliffs. Tushar Wash and Floy Wash both have tributary canyons with them. Fun to do if youve got a few hours to kill in Green River in the evening or something.

    Also there are some in the Book Cliffs northeast of Junction, and I think Big Wash, in the Plateau Creek canyon, may have some slows/narrows in the Green River as well.
