Great series. The GC is hard to shoot unless there are some clouds or something to add interest, and you got that. I once lucked out and was there for a snow and it became very photogenic. Your slot-canyon shots are awesome.
For stars, use the largest aperture lens that you have at a fairly wide angle. The general rule is to keep the exposure under 25-sec. by upping ISO as needed. The ratio of the aperture to the focal length can be used with a formula for an even more precise time, but the larger the aperture relative to the focal length, the better. Still, 25-sec. usually does the trick. Try wide-open, at ISO 1600 for 25-sec. as a starting point. My biggest problem is getting focused. You can't just choose infinity. I try to find a really bright start and use Live View manual focus at 10x view. Lock the mirror up and use remote release or self-timer on a very sturdy tripod. If it's windy, you might as well come back another night, unless you can get behind a big rock to block the wind.
