This is the online bibliography for Cascadia Revealed and Natural History of Pacific Northwest Mountains. The Recommended Reading on page 550 of the printed books lists the books I recommend most strongly, whereas this online bibliography is mainly for scientific articles.
Its primary purpose is to give credit to the many brilliant scientists who supplied hard data that went into the book. Secondarily, it offers leads to any readers who may be looking for more scientific detail. Many of these papers can be downloaded via Google Scholar. I recommend going to Advanced Search, writing a chunk of the title in the “exact phrase” field and searching for it “all in title.”
Of course, it wasn’t possible to provide citations for every single bit of info. You will find that to some extent I’ve selected the science that I think of as “recent findings”—science that has not yet been repeated for decades in reference materials, including other field guides. While I list relatively recent papers preferentially, you’ll still see plenty of 20- or even 30-year-old papers listed here, ones I especially want to acknowledge. At the other extreme are some papers from 2016 and even 2017—too late to make it into the book; they tend to be updated versions of papers that did make it; so the new version is more useful for you to look up.
I also tried to include citations here for each case where my book quotes directly or refers specifically to a “study” or a “scientist who found…” There are a couple of those I’ve lost track of, but I’ll keep trying to relocate them.
[Please excuse small inconsistencies in citation style; they allowed this digital scrivener’s task to go a little faster.]

p 30 “Missoula Floods”
Of several good books on the floods, I especially recommend:
Allen, John Eliot, M. Burns, and S. Burns. 2009. Cataclysms on the Columbia: The Great Missoula Floods. Rev. ed. Portland, OR: Ooligan.
p 30 “given that early Americans” On the earliest artifacts from southern OR:
Jenkins, D.L., et al. 2012. Clovis age western stemmed projectile points and human coprolites at the Paisley Caves. Science 337, 223-228.
Stay tuned for possible earlier evidence. In March of 2015, University of Oregon archaelogists issued a press release on a find that they described as a 15,800-year-old scraper. They have not published any such findings yet in scientific journals, so I’m considering this one a long shot.
The question of whether early Americans saw the floods is addressed directly by Richard Waitt (2016) who concludes that they were not around here in time to see the last flood from Lake Missoula, but they were around for later, smaller megafloods that came down the Columbia from one or more other glacial lakes, most likely Glacial Lake Kootenai in British Columbia. Where those late floods came from is not at all settled, though. For example, Hanson and Clague (2016) attribute floods from around 13,400 years ago to Lake Missoula. Though they disagree as to origin, these papers agree that the late floods were much smaller than some earlier ones.

p 31 “British Columbia had glacial lakes and catastrophic floods”

Speculation about these was provoked especially by Shaw (1999) but that paper’s details about the Missoula Floods have not been well accepted.

Chapter: Climate
p 34 “a lenticular (lentil-shaped) cloud”
Lenticular is usually defined as lens-shaped. Well, okay, fair enough. But the Latin word lens originally meant lentil, which then, once lenses were invented, suggested a word for lenses.

p 98 “two papers unmasked an abundant lichen as a partial parasite on oaks”
That statement now seems to be debatable, at best. I know those papers exist, but I am currently unable to relocate them. This suggests that that finding is not cited or widely accepted in recent decades and they have fallen into obscurity. The amount of nutrition the authors thought they detected was minute in any case. Lichens of North America summarizes the issue thus: “A number of lichens… live only on trees with smooth, living, green bark… perhaps indicating that they actually derive some nutrition from the green bark cells (although there is still no evidence to prove this).”

Bradley et al’s choice of Vison vison (a change from Mustela vison in the previous checklist edition) puzzles me. Their references include both Harding and Smith (2009) and Koepfli et al (2008). Those two studies see a clade combining the mink with either the four New World weasel species (Harding and Smith) or just the long-tailed weasel (Koepfli). I think that should mean that you can only take the mink out of Mustela if you also take one or both of our weasels out of Mustela. I suspect this present nomenclature for our weasels and mink may not last long.

p 512 “The CRB may have been an earlier production of the Yellowstone Hot Spot.”
Hard to choose from the many papers on this. Here’s one that sees it all starting with the CRB:

p 514 “question of how far it slid and when… is called the Baja BC controversy”
In general, geologists who place their faith in field study are skeptical of “Baja BC”, and those with faith in paleomagnetic study and seismic imaging favor it. For example:
Monger, J.W.H. 2014. Seeking the Suture: The Coast-Cascade Conundrum. Geoscience Canada 41(4): 379-398.
Colpron and Nelson (and many others) reject “Baja BC” in favor of relatively modest terrane motions in the Cretaceous, but they track very wide terrane wandering earlier on, before the terranes neared North America:
Colpron, Maurice, and Joanne L. Nelson. 2009. A Palaeozoic Northwest Passage: Incursion of Caledonian, Baltican and Siberian terranes…. Geological Society, London, Special Publications 318(1): 273-307.
Hypotheses supporting “Baja BC” have been nurtured for years by Stephen Johnston, among others, and recently reinvigorated by Karin Sigloch and by Robert Hildebrand.

I should note that this mainstream view of several decades standing is questioned by some who doubt the Ancestral arc extended north of Snoqualmie Pass:
