Not much context given. Just in a phrase "You have to dismantle the blockage/barricade of stones to make your way there." And I'm pretty sure that it refers to rocks/stones heaped after a rockfall. Maybe on some mountain road.
P.S.: I'm doing a translation of a text on my own, so I might not feel some subtleties of English. This is why I'm asking you this question.
Interesting. Usually you dismantle something that has been built intentionally - e.g. a machine, a house, etc. Thuis this indicates that someone placed them there intentionally, and they would be a barricade.
If the stones arrived by a rockfall, you would remove the stones.
So again, is this an adventure game of some sort? Who is the person who will have to dispose of the stones? Why is he there?
Yes, a kind of. Probably you are right about removing them, thanks for making that point! I only wanted to know what term I could use for a heap of rocks formed after a rockfall, as I thought that there was some term out there to describe a pile of rocks that blocks your passage.
