I took this shot in the Caucasus. My friends and I crossed the Guam Gorge on foot, and in the morning I left the group because I wanted to get here to the Eagle Cliffs. Since I didn’t know the precise location of the trail, I knew I had to get my bearings “by azimuth,” as explorers say, from one of the glades on the outskirts of the village. Twilight wasn’t long in coming. The moon shone for a while before disappearing over the horizon. On the moonlit part of the cliff, somewhere to the right, a bird was squawking all night. Eagle Cliffs, so perhaps it was an eagle. My gas lamp was clearly upset about it.
