I was in Yosemite a few summers ago with a couple friends from college. We happened to arrive at the same time as a party of Udibe with their U.N. guide and bodyguards: my first real life encounter with aliens.
Seems they wanted to climb El Capitan. We were scheduled to make our attempt that weekend, but after some negotiating we gave up our spot, and up went the Udibe. It took them about 15 minutes total. Their wide, eight fingered hands are apparently very good at grasping rock, and they explained that they’re used to about twice the gravity.
