>the first photo was shot close to the groundI hope you enjoyed your time here.
The picture is of a route called "separate reality" and the crack in question is about 600 feet off the ground. You can see the Merced river and the road far down below in the picture.
"Famous for its exposed overhang, this crack sits a perilous 650 feet above the Merced river. Wolfgang Gullich was the first to free solo it, but it's a true "trophy climb" that's also been done by Heinz Zak, Dean Potter and Alex Honnold. On reaching the top, Gullich noted, "I suddenly had an impression that it was not a game of gambling with my life; it was not subjectively dangerous. It is the thought of death that teaches us to value life."
"In a way, this is the perfect solo. Only five people have ever done it. It requires commitment from the very first move and finishes with a foot-over-head inversion. Any single part of it could rate it as the most exposed single pitch on Earth."
