Aha, I was looking for them in the skyline, not the foreground. Indeed more than obvious, agreed !

We all appoint Rick as the winner!

Next is #91 - about.

Yay, I win something!

#91:

Could be easy, could be not. We'll see how it goes, let's first wait and see if someone directly recognizes it!

Hmmm... sun, green, limestone (however I see sth like quartz behind), dwarf pine... I'd say the Alps, somewhere near the Dolomites, or Slovenia, or the Vienna's pre-Alps. What mountains could have such visible twisted sedimentary layers ?

Aha, you're taking the geological approach to solving the puzzle

Well, in this case I can tell you that the mountain is the highest point of this particular dinosaur-bearing formation (or rather, the internet can tell you).

Geological-botanical in this case (vegetation often tells a lot about what part of the world, at least in Europe)
The only problem is that my knowledge of the Alps is near zero... I think Borut or Vid would solve the enigm.

I'll leave it like this for a little while, I'd be interested to see if someone recognizes it instantly. It should be sufficiently well known in its neighbourhood...

Nobody recognized it yet, time for a new clue:

No idea about the english word for it but we call this in french "montagnes Russes"; would your mountain be much further than I first expected ?

Hah no, the clue has nothing to do with the name... I didn't know these things had such 'mountainous' names in french.

The mountain is a little further to the west than you initially guessed though.

Is the altitude less than 2000 m

Cret de la Neige

I'd say there is too much dwarf pine, a feature rather found in Dolomites and Central Europe, to be in the french/swiss Jura

Diego, twice no.

Let's add some pictures taken from high up the mountain, in three different directions:







Hopefully this will help with the geological approach to determine the location of the mountain in question If not, then I'll add a much more clear hint on its location tomorrow.

In Europe?

Yes, it's in Europe.
