Third: 1265 seconds (about 21 minutes) @ f/4 ISO 100
The first and second shots took place around 5:00pm. Their purpose is to record detail in the trees and rocks. The third exposure started just after 10:00pm and recorded the star trails around Polaris and the cabin lights around the lake.
so you left the camera in that exact spot for 5 hours??

All you have to do is put the camera into Bulb mode, start the exposure, then walk back 21 minutes later and stop it. You really don't have to be that precise with star trails.
The tricky part of this shot really wasn't the exposure(s), it was setting the camera up in the daytime so that Polaris would be properly framed at night. You can't see the star during the day, so framing is the difficult part.

But actually, it was more like 7 hours. I took exposures every couple hours starting at 2 or 3pm, but I ended up liking the ones around 5pm best.

You definitely don't need an SLR to do HDR work, just a tripod if you're going to take a few shots at different exposures. Drive around one day and look for a nice sunset or a cool building. There are hundreds of things even in your own home that would make for a cool HDR image. As srika said, just use your imagination!

Come tell these clouds in Oregon to go away, so I can get some light that isn't grey!! I've hiked about 11 miles so far over the last 2 days, but it's all been in totally solid cloud cover. 
I'm trying...

those star trails are insane... is it common for them to follow a circular motion like that or is that something exclusive to this region?

Great shot, Dan. Star trail shots are cool and really put things in perspective for me. We are so small compared to the vastness of the universe. And we're spinning.
Shots like that really make me think.

Looking at that photograph inspires the same emotions in me as watching an Olympic athlete. Awe. Amazement. Disblief. "How do people do that?"
Dan, I am well and truly impressed. Great work.

It has been kind of gloomy the last few days in the NW. Just what I needed, pictures or no. Besides, even with the cloud cover, I'd never do these hikes this time of year back home...too dang hot!

Dan, I have to say that the next subject as much as we might want it, can't be honeymoon.
