Snowflake Frozen (Zombie?) Thread

Please forgive me if this has been discussed already-- but I'm developing a game set at Telgar Weyr and this topic has been on my mind:

We all know that cold temps "freeze" Thread. But does it immediately die, or is there a temp range where it goes dormant and can "thaw" if the temperature rises above a certain point?

I've been considering the climate in the upper Northern Barrier Range where Telgar is located. My conclusion is that it would be very similar to a boreal climate on Earth (I'm thinking the NW Territories in Canada, but I'll take other suggestions!)-- meaning only a few months of the year have daytime temps significantly above freezing, but the majority of the time temps hover around or below 32*F.

In my game, Telgar and Igen Weyrs have combined their population and protectorate. This would put them in charge of fighting Thread over a huge chunk of the Northern Continent. My theory of how this is possible: a large section of Telgar's original protectorate consists of cold mountain range and for most of the year the low temps should kill Thread and free the riders up to worry about the warmer, lower altitude portions of their protectorate.

The scary part of this being-- what if the Thread isn't dead but dormant, and comes back to life when it thaws? ZOMBIE Thread!

Whew. Talk about a huge first post! Feel free to tear apart any of it that is patently erroneous. And hello everyone!

TL;DR version- is frozen Thread dead? Or can it come back to life and start eating things once it thaws?

It SHOULD be able to revive: otherwise it would never attack anything. Afterall, it has spent a very long period frozen in space and it is only the friction of entry that has activated it.

The hard shell that protects Thread from 0 degree temperature burns off in the atmosphere, leaving the innards to fall to Pern. Therefore the innards should always freeze to crackdust in the right conditions, because they no longer have protection.

Sorry. It's a fun idea, however.

That's what I was thinking, but I wanted some other opinions on the matter. Because how terrible would it be for a high-altitude Fall to happen in the morning and once the sun comes up about midday, the Thread thaws out and starts eating everything?

I just finished Dragonsdawn this afternoon, and toward the end of the book some of the characters mention a Fall taking place over the mountains and they essentially decide they don't need to meet it because it's over the mountains and who cares anyway? I think this implies that maybe even if Thread falls on a mountainous region, it will have very little vegetation to eat and won't be able to burrow because of the stony ground.

I'm feeling more comfortable about my theory now. I think it's safe to say that any Thread that isn't frozen to death by the cold temperatures will starve.

Somebody has done a study of Thread written as a scientific paper. I can't find my copy of it.

They don't fight thread much in the colder regions during winter.

In Dragon's Dawn they did not have the man power or equipment to fight every fall, so if it was unlikely to spread they did not bother. In latter passes I think they fought more falls to prevent spreading, even if it was not over a populated area.

Actually I am not sure how thread survives at all in the upper atmosphere after the shell burns off. The Atmosphere on earth is as low as -30f at 30000 feet also the thread shells hit the atmosphere at over 20000 mph and after the shell breaks anything in the shell would still continue at that speed continuing to burn. So even if it survives entry into the troposphere the low temps would freeze it to dust.

The was shown in the book Dragonseye/Red Star Rising The weather wasn't right at Fort and High Reach but it changed to a warmer front at Benden.
