    These interesting photos show a very small area. How big is Moon Valley?

    It’s not very big. You are right that the pictures only show a small area, it was a Sunday and very difficult not to include a Brazilian in a sunga or a minuscule bikini! Hence the tight shots...

    Hey I want to see the chic in the bikini..!...

    Nice limestone rock formations

    Ha! I'm sure you do!

    Is it limestone? My first thought was sandstone but I'm no geologist.

    The second is very good. With the first one I have a lot of trouble making sense of what I'm seeing.

    Thanks Cornflake, as I said it was difficult to convey a better sense of the place, I'm hoping to be able to go back on a less crowded day. I'm no geologist, but found this description online:

    The Vale da Lua represents the best-known outcrops of
    the basal unit of the Paranoá Group, which can be classified as
    a sedimentologic, stratigraphic and geomorphological site. The
    rocks of this unit are constituted by matrix supported
    conglomerate, badly selected, of gray color and carbonate rich,
    and this last feature is responsible for the differential action of
    the fluvial erosion, that results in peculiar forms of great
    natural beauty sculpted in the rocks. The São Miguel
    conglomerate was affected by important diagenetic processes,
    related to the recrystallization of most carbonate originally
    present as matrix and now considered as a "pseudo cement",
    that now corresponds, on average, to almost half of the rock
    composition. The characteristic evidenced by thin sections
    analyses show that the rock (clast and matrix) were submitted
    to low-grade metamorphism. The Vale da Lua is well
    preserved and to keep this condition it is necessary to increase
    the information to the visitors about the rocks conditions
    formation (including depositional and sedimentary processes),
    once there is great confusion by part of the public, and many
    believe in volcanic origin to the local rocks. It is important to
    emphasize the warning plates, the importance of the area
    preservation, the prohibition of getting rock samples and the
    general maintenance of the place.

    Here's another pic

    Wow, Cristóbal I love these shapes. Nice contrase with the flowing water and the jagged stone shapes. Really nice exposures, too.

    Thanks Sara, it is a unique location for sure.
