"FreeBASE": Dean Potter on the Eiger Nordwand

On August 6, 2008, Dean Potter completed the first "FreeBASE" ascent of Deep Blue Sea (5.12+) on the north face of the Eiger (13,025'), Switzerland. He scaled the slightly overhanging limestone route solo, sans rope but with a five-pound BASE parachute for protection against the consequences of a fall.

Last year, Potter was introduced to Deep Blue Sea by mountain guide and photographer Beat Kammerlander. While they were stormed off the face on Pitch 5, Potter said he recognized the potential that the route held for a FreeBASE ascent. He saw the opportunity, as he described, for "solo mentality and freedom without instantaneous death." Had it not been for the inclement weather conditions, he would have tried it then, he said. He returned to make his attempt this summer, and though weather conditions were similar, Potter was positioned for success.

For half of the month, Potter lived in a cave 9,500' up the Eiger's west ridge. For the other half, he lived at the Horner Pub in Lauterbrunnen, as he describes, "dipping into a sort of a barfly existence." He filled his days with pushing his limits on overhanging limestone routes, honing his technique, and BASE jumping the cliffs in the mountains surrounding Lauterbrunnen a few times a day. When the weather offered a window, Potter made his climb.


From the northwest arete of the Eiger, Potter traversed along a ledge to the base of the 600' headwall. The route from the arete allowed Potter to avoid the lower sections with loose rock—should he have sustained a fall so low, he would not have been able to deploy his parachute with enough time to land safely. He describes the first part of the climb as "gently overhanging, pumpy limestone sport climbing. The upper crux seems a little harder, with bouldery 5.12+ side pulling flared jamming."

"During this FreeBASE, I was able to relax and fully groove during the climb. Additionally, it has opened my emotions and mind to the limitless possibilities. FreeBASE climbing Deep Blue Sea has stirred my way of thinking more than anything in the past," Potter said.

"Yail Bloor My bet is he pulls a Dan Osman by early next decade."

Yail i think you won the bet. He met Danny at the skies, in May 2015, while base jumping in a wingswit.

Ironically they both died while free falling and not climbing, even though they were daring climbers.

Yeah I'm curious about the rig as well. What size canopy? Slider up or down? What size PC?

I mean really, what would his game plan be if he did come off? Relax, get belly to earth and start tracking? Or relax, get belly to earth and deploy immediately? This obviously depends on the how high above talus he is when he comes off, but nevertheless I would like to know what his thoughts are.

Congrats Dean! That's some good shit right there.

Superb style.

Having handled and packed a few base rigs, I am pretty sure Dean was not using a conventional BASE configuration. The weight alone tips you off but the narrow profile and sparse harness are clear as well.

A very tidy piece of kit that does open up a range of tactical/style options.

Does anyone know who sewed that rig?

If you are going to do it, you better be able to land it! Dean, it appears, has learned how to land his canopy well enough to risk cluttered landing areas. A very necessary skill.

Congratulations to Dean for his demonstration of the possibilities.

Amazing stuff. Dean is such a touchable hero. I met him one damp winter morning in the Curry Village Parking lot. He asked- what are you guys climbing - he was genuinly interested in our overprotected scampers at Knob Hill (easy 5.8 - 5.10). A true inspiration.

grande dean!

Absolutely amazing, total respect for Dean and what a great story!

Totally and utterly far out! That is the most outrageous thing I have heard of in this sport. Right on Dean, you're crazy man!
