Puiselet
Hi peoples, bonjour, mon amis de souterrain
Hi peoples, bonjour, mon amis de souterrain
I bring you here a little photo report of Puiselet sandmine.
I wanted to do it with some infos and history to the sand of Fontainebleau, quarried on and under ground in the area.
I found some good info about it, but all in French, which I can neither understand in a correct way, nor translate into English.
Sorry
Seems it's about 30 millions years old, very clean and used for the production of glass and more.
Partwise the sand is very fine, stored in layers of a few meters of hight, some is fixed to something like rock and you also find bigger rocks of hard sandstone,rounded by the weather, stapled to hills with sand between.
These are used for bouldering, high difficulty climbing in low hight and risks.
I saw huge sand quarries in the area, working and abandoned,
even an abandoned street, cut by a newer quarry; you can still get on it, but it makes no sense,
(only for that motorcycle licence training I saw).
Also no sense to take a photo of a street which looks like a street
-
pretty white sand, embedded in other kinds of sands, maybe 300m wide...
-
n°1
-
...ten meters thick maybe
-
n°2
-
they quarry different sands, colours, size, quality perhaps
-
n°3
-
that's what it looks around Puiselet sand mine, rocky places appear, but not everywhere.
You got lots of forest and just fields there.
-
n°4
-
that's a relict outside the quarry
-
n°5
-
ok, in now
a piece of rail with iron sleepers, used as a ladder
-
n°6
-
I hope they are not only based on sand
-
n°7
-
some sand is solidified, some not
-
n°8
-
looks good, does it work good too?
-
n°9
-
n°10
-
much looks like this
-
n°11
-
there we go, down to the dead end; the brown in the ceiling is iron I think, rust
-
n°12
-
what's wrong here?
-
n°13
-
other place, but this thing does not anymore reach the ceiling, something moves
-
n°14
-
girls, they freeze on their way home
-
n°15
-
I have to say, these pics are not in the order of my way, I mixed them up
-
that's made by permanently dropping water..
-
n°16
-
...and that is a hole to a lower section of the mine
how nature created it, I don't know, water or whatever and when ?
-
n°17
-
fix layers between the sand
-
n°18
-
again a bit space to the ceiling (but this could move sideward)
-
n°19
-
what makes that colours ?
-
n°20
-
big hall, party place
-
n°21
-
my camera made problems, so these both are taken with little Ixus100
-
n°22
-
some meters of rail, I think the should be much more, covered by the sand
-
n°23
-
if it works...
-
n°24
-
another example for fixed sand. Did there water flow in it and bring chemicals?
-
n°25
-
here comes the ceiling down
-
n°26
-
I like this shot
-
n°27
-
now two examples for same place looking very different, using different light
-
M7 torch this..
-
n°28
-
...and this with with home made 12V warm white lamp (most used in this report)
-
n°29
-
and the last one
-
n°30
-
keep care in dark holes
