How in the heck can I get to Ysgramor's Tomb with the mod Frostfall active without freezing to death? It appears to be in the middle of an arctic sea. I doubt I could swim to it. Is it possible to find a path over ice floes to it? It will be bad enough carrying a ton of firewood since there are few trees.

This mod (http://www.nexusmods.com/skyrim/mods/29170/?) has a water walking spell which will allow you to cross the sea without freezing to death.

You can make/buy a few bottles of Snowberry Extract just in case you fall into the water. You'd still get wet, though, which would most likely increase exposure rate.

You can also use one of the Water Walking potions from the Dragonborn DLC (you can find two in Raven Rock Mine/Bloodskaal Barrow) or Ahzidal's boots. Or you can use one of many mods that add Water Walking spells/enchantments/potions to the game. http://www.nexusmods.com/skyrim/mods/55590/? has enchanted/disenchantable gear with the Water Walking effect if you don't want to go through the trouble to get Ahzidal's boots.
