are you sure the pictures arent altered?

no ....its a real place

people sneak up there to take photos

hmm

have to wear gasmasks

sulfur flames wouldnt show in daylight

well ,im not sure what it is ,but its a real phenonomena

have you ever watched powdered or sulfur stones burn?

thats what they say it is

they dont show up because everything else is brighter than the flame

not really no

i have

i have sulfur

you cant see the sulfur flames during the day time

its burns faint blue

or in sunlight anyway

could be a mixture of gases or something ,i dont know ,find the colour interesting though reminds me of the electric blue algea that turns the sea into blue

also i dont recommend burning sulfur inside

the light is still released
Its just you cant see it with all the brighter stuff arround

dont burn sulfur inside

do you mean the light from the flames? if so, ofc

yeah apparently you have to wear gas masks to go up there

not meant to go up

i dont remember for sure, but i think the fumes effect your eyes too. its very harsh

and if i remember right that lake by it ....if you fall in you die

acidic or something

hmm

hangon off to google that

like i said, the blue looks much too bright to be from sulfur

Its in the night time

also exposure can make it brighter

yeah i noticed that in some pictures

yeah its that place

if you fall in the lake ...you wont be getting out

Its sulfuric acid

there are organisms that thrive in waters like that

yeah

bad way to die

yes very

no thanks
