Help me reconnect with partner

Please excuse my English. I am an American climber, this September I climbed Central Pillar of Frenzy in Yosemite with an Austrian climber. I did not get his email address or contact information, but I would like to find him. I believe his name was Arcos, he was on a trip in the USA to climb in Bishop, Yosemite, Moab. In Yosemite he was very excited about the climbs on Arch Rock. He was an excellent climber and he taught computer programming. I believe he was from VIenna. If you know who I am talking about, or if my climbing partner sees this post, please email me: [email protected]

Thank you,

Jack
