A lot of photography depends on luck. We try to be in the right place at the right time, and often it works. Certainly we would get nothing if we didn’t try. An example is the weather. Obviously, rain or clouds or other difficult conditions can put a damper on making good images, but a less tangible factor is haze. There’s no good way to forecast haze in the wilderness (although it is more common in the summer), so it can squelch the best plans. In 2003 on the High Road, Abby and I dealt with haze brought about by forest fires in eastern Arizona, which spread out over a huge region.
The examples here are from Canyonlands. The first image is from November 2007, on The Next Cairn, and you can see how hazy it is. The second was made at about the same time of day, and from near the same spot in March 2004 (The Confluence), and as you can see, it was very clear at the Grand View Point that day.
