The first real mountain I got to the summit of, a 14,000 footer in Colorado. As you can see in the picture it didn't involve climbing, just hiking (but over a lot of talus). We basically followed the ridge line. I learned what "false summit" means. :)
We got a jeep trip to the tree line and then it was up to us to get to the top and back down to the ranch. I signed the register at the top and got a card confirming I made it to the top. But, I lost the card when I lost my wallet riding the Big Dips at West View Park. Sadly, I don't remember the name of the mountain.
The excursion was part of a summer St. John's Lutheran Church trip for teens to a dude ranch. I was thirteen or fourteen, don't remember exactly.
