Not sure how I missed this trip report until just now. Great work, and even better photography.
A couple questions, if you don't mind: what lens did you use for your photos? As far as I can tell it's an ultrawide zoom of some sort (maybe a 16-35mm f/2.8?). Regarding the dynamic range pop of the landscapes - is that the result of a polarizer/graduated ND filter or maybe a color filter done in post (perhaps a combination of all 3)?
Also, did you bring a tripod for the long exposures? I ask because I opt to use natural features on the trail as support in place of a tripod. It's hardly ideal, but better than lugging my tripod around in the backcountry (despite my current tripod being of carbon fiber and magnesium construction, it still weighs 4lbs w/ head and never seems to make it past the trailhead). Living as both a photographer and an ultralight backpacker, I've gotten used to the two identities being constantly at odds, but I love hearing about how others manage to make it work for them.
