The first hardness test is the "difficult crack", where the rock offers hardly any gripping surfaces. If there are difficulties, then this is a reason to turn back. Further challenges lie ahead. One example is the the forbidding Flatiron, which can only be handled with picks and crampons, or the ramp to the waterfall chimney, which arches above it. The mountaineers at the Traverse of the Gods need nerves of steel. "This passage is eerily exposed with an unobstructed view 400 meters into the depth." There are also peaceful moments on the wall, however. For example, on the evening of the first day in the bivouac on a small rock formation. "High above, I'm sitting in the middle of the Eiger north face, looking at the many distant lights in Grindelwald, and a sense of tranquillity comes over me," enthuses Abegglen.
