When doing a dawn hike on Mauna Kea it is important to choose your altitude with care. You really want to be right at the top of the cloud layer. There, where the fog drifts over in alternating shifts with the sunlight, there is where the magic happens. Mamane in the fog, puʻu appearing and disappearing, and fogbows. Add fog and you have all the ingredients for some good photography.
The plan had been to spend the morning on the summit doing some testing. When that got cancelled I quickly dropped into plan B… Go hiking. I got the altitude right.
