Frostbite Update

I wrote recently about my frostbitten fingers following my ski down the Maple Mountain/Hall trails at Jackson NH. I was using the term loosely but, not knowing anything about frostbite, I wikipediaed it. While I don't have blisters, the superficial skin of both right and left middle fingers is dead. There is no edema deep to these so this skin sort of feels callused. Hmm. I'm pretty sure no amputation will be necessary.
