  1. Quick thought: if it IS an ice dragon in that cave, maybe the reason it didn't melt away when it died is...IT'S NOT DEAD!!! Dormant dragon anybody? And continuing the spitballing, what if the Horn of Jorumun's 'giants from the earth' is something about an ice dragon beneath the earth waking up and shaking the ground...
  2. Try this thread out: I contributed quite a lot to it, and in my opinion it is well worth the read.
  3. Lakes are fed through a combination of these mechanisms: Direct precipitation (ie rainfall) into the lake Surface run off, both in the form of water running over the ground and through small streams (here including Rippledown Rill and doubtless countless others) Throughflow (water moving through the soil) Groundwater flow (water moving through the bedrock) Springs feeding into the lake from below The lake does indeed lose water from a combination of evaporation, outflow from rivers, and percolation (water seeping into the bedrock). However Jaak makes a very good point about the river, and the rest is a simple case of inputs > outputs. Love this idea Steelshanks
  4. I just love it when I have an excuse to reference this thread: Trust me, it's well worth the read
  5. Welcome to the forums! Skagos is a dormant or extinct volcano, which explains its shape, topography, and the obsidion. I'm certain that the Skagosi do have knowledge pertinant to the fight against the Others, even if it's just a dedicated obsidion-equipped fighting force or something. I posted something a while ago which touched on the relationship between the Skagosi and the Ibbenese, although I confess I didn't flesh it out much. It doesn't directly relate to this topic but you might find it interesting. http://asoiaf.westeros.org/index.php?/topic/141326-a-theory-on-the-ifeqevron/ I think Skagos is going to be important soon: Rickon and Osha are there, it's a good way for GRRM to conveniently boost the Northern troop numbers, and it's possible that during the Long Night II it'll be connected to the mainland by sea ice, which would change the whole dynamic considerably.
  6. Hmm, true. Although as a businessman, , Illyrio might be pragmatic enough to put his own feelings aside? You're probably right, it was just a thought I had. There's also this:
  7. I like this theory, but remember that Pentos historically hasn't gotten along with Braavos. Might I suggest a slightly different approach: Illyrio is trying to manipulate the Braavosi into a situation where they'll be facing off against the Dothraki, Volantis, Slaver's Bay, Myr, Lys, Tyrosh... so that Pentos will finally be free of Braavos' restrictions and be able to become a great power in the Narrow Sea again?
  8. @Bobity. Welcome to the forums! It's so nice to see another volcano thread, I was beginning to get bored. At the risk of blowing my own trumpet, you might want to check out my own theories in my signature. Volcanoes are my speciality on these boards: I always get involved in topics concerning them. I agree with you completely that volcanoes are very significant in the books, not least because they provide a good location for dragons to live. You are correct about Hardhome being a volcanic disaster (note that the quote says "waters choked with swollen corpses" - bodies in water will become bloated regardless of whether they were killed fleeing a volcano or not), Winterfell is obviously an example of geothermal heating, and well done on remembering Marahai! Not many people do. I also think that the Mother of Mountains is likely to be a volcano, and as for the Shadow (oh boy) let's just say there are definitely lots of volcanoes in that area (if you're curious I can give you more evidence). I also really like your idea about the gender switching! I'm making that my new working hypothesis for the future. I really don't think Hardhome was a dragon attack. The evidence is nigh-conclusive that the city was destroyed by a volcanic eruption. Have you considered the Cape of Eagles here? It bears a remarkable resemblance to Banks Peninsula in New Zealand, and this being a (possibly extinct) volcano would explain the basalt blocks in nearby Moat Cailin. I think Bobity. is talking about fused Valyrian stone, rather than the notorious oily Black stone. Is that the source of confusion? Lord Vance II, we've had some interesting geography-related discussions before, so it's good to see you in this thread as well!
  9. The pool is cold because it is deep, shaded from the sun, exposed to the elements, and because it's in the North. The Winterfell walls and springs are warm because of geothermal heating. It is perfectly possible for the pool to be separate from the spring, and the two do not preclude the other from existing in the same area. Yes, but those hot springs are heated geothermally. The godswood pool is not. End of. How do we know this? For all we know there are other smaller ponds in the area that aren't mentioned. I'm afraid I have to disagree with your conclusion here. Just because an area has a lot of hot springs does not mean that every body of water in the area has to be warmer than otherwise. The pond may not come into contact with a geothermal heat system at all. Also bear in mind that 'deep' in this context just means beyond the ability of anyone to swim the the bottom of: it doesn't mean bottomless or miles deep or anything. Given that it's a freezing pond in a society with medieval technology, that could be as little as 20m or so (I'm not an expert on free diving or anything mind). I see absolutely no reason to suggest the pool is anything other than mundane and natural. Actually, GRRM is famous for carrying out extensive research on his topics, and he is a literal genius after all. Given the depth of detail he's laid out for volcanoes, tectonic plates, and geothermal heating in the books (which I can go into further if you're doubtful) it's more than clear that he knows his stuff.
  10. Ah, I understand what you mean: you're saying that the Shivering Sea is actually composed of the Northern, Arctic, and Essosi plates, like the Atlantic is made of the American, Eurasian and African plates? Yes that's an interesting idea. Of course it's pure speculation given that we don't have a map of the entire arctic region, but speculation is fun! One thing about your RRR at the Narrow Sea: I suspect it would more likely be a TT? junction instead. The three plate involved are Southern Westeros, Northern Plate, and Western Essosi plate. The plate margins are in the Narrow Sea, along the Neck and Three Sisters, and (presumably) somewhere along the northern coast of Essos, be in in the ocean or on land. Thus the plate margins form a 'T' shape. However the Northern/Southern Westerosi plate is a divergent boundary (Northern heading north, Southern south) and the Southern Westeros/Western Essos margin is the same (Southern west, Essos east) - all relative to each other. These would both create trenches (T) instead of ridges (R). The reason for the question mark is that I don't think we know enough about the movement or shape and size of the Arctic plate to come to any judgements about it, but I'd be interested to hear your thoughts. I think you might also find this website interesting: http://web.stanford.edu/group/anthropocene/cgi-bin/wordpress/game-of-thrones-geology/
  11. So I just remembered that Winterfell is composed largely if not exclusively of granite. Granite is an impermeable rock, and it may well have been mined in the region. This may indicate that the underlying geology of the region is predominantly granite, which would make the existence of an isolated deep pool more likely. However the complex cave system beneath Winterfell is indicative of a karst landscape (limestone). It's possible that the granite was extruded out on top of the limestone, that plates of granite were lifted on top of the limestone as tectonic plates shifted, or that there is in fact only a smallish area of granite and that most of the stone used in the construction of the castle was mined elsewhere. The pool may even have been an artificial feature created for the godswood? Oh yes I forgot about the ground level. You may be right on that. Exactly! Occam's Razor here
  12. I always thought it was just a standard (albeit very deep) pond: not connected to any of the hot springs. Because of this, it's volume, the fact that it's shaded by trees and the fact that it's located in the cold cold North, is enough to explain its temperature IMO.
  13. Could you please clarify what you mean by that last sentence? I'm afraid I don't quite see what you're driving at. Once again, I don't feel confident making assumptions about the possibility of an Arctic plate, although there is certainly a convergent boundary at the Frostfangs.
  14. Because Dragonstone and Driftmark are volcanic they are almost certainly formed by a plate boundary in the Narrow Sea. Now they may well be on the Southern Westeros tectonic plate: inter-plate volcanoes are usually not directly on top of a boundary. I've put quite a lot of thought into plate boundaries, and so far I've concluded that we have the Southern Westeros plate (Red Mountains to the Neck) moving in a westwards direction, while the Western Essos plate (Free Cities to the Bones, excluding the area around Valyria) is moving east (all relative to each other). Meanwhile we have, as we are agreed upon, the Northern Westeros plate splitting away from its Southern counterpart. If you imagine these boundaries drawn on a map, this leads me to conclude that the Shivering Sea (at least up to Ib from Westeros) is wholly or partly another plate by itself. I'm reserving judgement on the possiblity of an Arctic plate as we don't have any maps of the whole thing yet (and likely never will ) We can agree to disagree then. Personally, I don't want to draw too many judgements about the lake's shape or size given the fallibility of all the different maps we have, and I find the argument of the glacial sheets all having narrowed by the time they reached the Riverlands (partly evidenced by the shape of hills and mountains in the area) convincing. However, I fully appreciate that you can see it from a different perspective, and I'm glad that we agree on its age.
  15. I do see your point about the seeming lack of other large lakes in the Riverlands. While I suppose it is possible that there are many smaller lakes that don't appear on the maps (and in fact this is to be expected anyway in a region with so many rivers), I do wonder if the area's underlying geology might hold the explanation. Perhaps the God's Eye basin is the only area where the rock is easily eroded, or maybe the glacial sheets narrowed by the time they reached the Riverlands. Yes, but the Yucatan crater is tens of millions of years old, so the crater walls (as opposed to mountains) have eroded away over time. If the God's Eye was in fact an impact crater only ten thousand or so years old then you'd expect it to still have it's crater walls. I'm still trying to decide whether the Mountains of the Moon are fold mountains or volcanic, but I do think the Neck is a divergent plate boundary, with small island chains and a region of geothermal heating.
