Are the Ruins of Gondolin underwater, or on Tol Fuin?

[SPACE_LEMON]

When Beleriand sank, the plateau of Dorthonion/Taur-nu-Fuin became the island of Tol Fuin. The highest points of the plateau were the Crissaegrim, which surrounded Gondolin. So, after the drowning of Beleriand, do we assume the ruins of Gondolin are above sea level, below sea level, or were destroyed utterly in the War of Wrath?

Personally I like to think that the valley of Tumladen wherein lay Gondolin became a bay of Tol Fuin after the drowning of Beleriand, and the ruins submerged, but not utterly destroyed.

I'm a little late to this party, but here's my answer:
I think as far as lore tells us: the only remaining lands of Beleriand and the Lands to the North after the War of Wrath are that of the island of Himring/Himling, Tol Fuin and Tol Morwen.

The highlands of Dorthonion and the Encircling Mountains around Tumladen were separated by the Pass of Anach, so there's possibly some form of geological fault-line between these two areas that leads to the Tumladen region sinking much more than Dorthonion does. Tumladen is likely the product of an ancient caldera lake that drained over time , which could give the possibility of geological weaknesses in that area. So bearing this in mind, the area could have sunk further after all the interference from the powers of the Valar who presumably take part in the War of Wrath.

So my take on this would be that a few of the tallest peaks of the Crissaegrim would be visible as small islands in an archipelago, but that that the ruins of Gondolin would have sunk a fair amount. As for how much was left after the Fall of Gondolin, I'm unsure. The city was certainly plundered, but I think Morgoth was perhaps too arrogant to order it be completely destroyed. Burning it and enslaving its people was probably enough. Very difficult to say if the ruins would exist after the war of wrath as the exact cause of the sinking is left very vague.
