American climbers Kevin Jorgeson and Tommy Caldwell are currently half way through the world's most difficult rock climb. El Capitan is the largest granite monolith on Earth at nearly half a mile high, and what makes this particular effort stand out is that the pair are free climbing the Dawn Wall, which is extremely smooth and challenging without climbing aids. They are only using ropes to break their fall, which adds to the extremity of the effort involved.

This Facebook post from Jorgeson shows how difficult the grip can be on the climb.

 

Jorgeson and Caldwell have both been documenting their efforts on social media, and in the best-case scenario are expected to complete the climb in the next two to three days.

Good luck, guys.
