To "starmoth": Yep, I'm also one of those interested in natural disaster/survival stories. I'm looking forward to reading this one. Also great, if you're not already familiar with them are: "The White Cascade", an excellent telling of the little known disaster of the nation's worst avalance in history, taking place here in WA St. in Mar 1910 at Steven's Pass in the Cascade Mts. There were numerous horrific winter storms following on the heels of one another over a week or so. 2 trains were stranded up there & in spite of desparate efforts to get them out, were unable to do so. There were soon multiple avalanches in that area, one of which tore both trains off the tracks & plummetting down the mountainside, killing around a 100 or more souls. It is a gripping read! There are also some related books, but which I've not read yet.
Also great are many of the Donner Party disaster books, which I am now working my through some of them, as well as a PBS documentary on the topic.
Thanks for your input. Hope mine helped you, too, & that I didn't ramble too miuch!
