I dont know, just guessing. And I guess there is a little steam on this pic.
And I came acros an area with much red on, but I only got this one here.
just if the eventually lava, have cooled below 100 dg celcius, there would be no steam.
Also we have come across some cracks with alot brown color on the sides.
Also I dont think water can be in (layers) its normal horisontal, and it simply just like thick to me, like syrup, idk.
