I’m voting to close this question because travel.meta.stackexchange.com/questions/8473/…

Noone is blocked from the photo, though - how would it apply?

@mlc can you explain more, the question you link to is not about photos without people.

@Willeke I think this is a reference to "Others are weird and not valuable."

Can you ask around others who use that garbage bin? I presume it was something like an office bin, not a public bin or dumpster you were trawling through.

@Willeke "I found this picture in a garbage bin and now I want to go there" feels very stalkery to me, or at least enough of a risk of being so that we should err on the side of closing unanswered

Lots of lakes in Peru look like this

@mlc This does not look like the kind of landscape where people live, especially given that the vantage point is looking down from a mountain.

I don't have enough reputation to vote as to close or leave open to this question. However, if I had, I would leave it open as it is interesting. I don't know where it is, I have guesses though which include Iceland and New Zealand. Hope someone knows.

@WeatherVane actually, it was in a public dumpster where I was throwing my own garbage (recyclable waste is thrown without bags in France where I live), so I cannot decently ask the people around

I would have thought, living in France, that in might be in the Alps (there aren't enough other mountains high enough around here to have this kind of glacier lake), but it might be from further away indeed.

a quick google search leads to berg lake in canada. The landscape looks very similar although I cant find the exact photo

@mlc just for what it's worth, your comments seem very strange / don't close vote !

If it's in a residential area, why not put a note close to the dumpster to ask? People are likely to use the same bin again :)

I don't (yet) know where it is in the world, but you can narrow it down a little as being somewhere that people visit regularly - there is a road or track in the top right of the image, to the left of the two pale stripes. It's either a drone/balloon camera photo or a satellite photo taken late afternoon and probably in the last 20 years from the retreating glacier (stone coloured on top = melting). Lowish altitude as trees. Lake might be longer now, but terminal moraine shape and lake edge on right hand side won't have changed much.

@uhoh plus there are lumps of ice on the lake - these are the high albedo objects in the water, particularly the big one near the left-end of the lake. It's high altitude or somewhere cold - there's snow on the ground in the left of the picture. I also don't know of any volcanic lakes that have a water exit that isn't also the one the lava came out of - lowest point and all. Presuming that the thing I labeled as glacier is a hardened lava flow.

@bob1 Convinced! The only ice I saw in Flores was in glasses :-)
