I live in Alaska, and I've met many of the people, and most of the PIs, who have dug dinosaurs out of the ground over the last ten years here. Most if not all of the dinosaur digs are on the north slope (there are some Mesozoic marine fossil sites elsewhere in the state, but I don't know of dinosaur sites except on the slope), and most of those are on the Colville River. I've been on that river, a few miles from the site, but I've not been on the site itself.
Several thoughts:
Also I'm deeply curious to find out what kind of "incredible hardships" they endured to reach the "Alaskan wilderness".
What the real paleontologists say is that the real hardship is funding! They use small planes and helicopters to get to this site, and it's very expensive.
The kind of hardships you'd face: It's going to be very windy - usually upwards of 25mph, and pretty continuous. It's going to be cold by most peoples' standards, staying in the 30's F in June. Its wet. You aren't going to have toilets, not even porta-johns. You aren't going to have hospitals you can get to within 12 hours. Bears
are genuinely interested in eating people in this area, and they don't warn you they are coming by shrieking. Wolves are generally harmless. When the wind does let up, there are nineteen billion mosquitos per cubic foot of air in the mid summer.
It really is a pretty unpleasant environment by most peoples' standards, and it is an objectively more dangerous environment than most dig sites.
The Colville site is mostly known for hadrosaurs. My understanding is that some of the discoveries there have significantly aided understanding of the fossilization process, but my memory is a bit hazy on that. There have been a few spectacularly preserved finds, mostly partials, but I've never heard anyone with credibility refer to unfossilized bones coming out of these beds.
There's a timeline for the Colville digs on the web (do a search - forum won't let me post links), which peters out in 2002 for some reason. More recent information can be found at the "Colville Virtual Base Camp" (again - can't link) website, where they have podcasts and everything. As you can see, the research these days is ecosystem oriented, and they are working hard on outreach and education. Perhaps that's response enough to the unfossilized dinosaur claims.
