Opened in 1920, Old Fall River Road earned the distinction of being the first auto route in Rocky Mountain National Park offering access to the park's high country. In the minds of many park visitors, the relatively subtle old route remains foremost. Unlike Trail Ridge Road, which is well known for being the highest continuous paved road in the nation, the Old Fall River Road is a much more "motor nature trail."

Craig Lloyd posted this challenge in the Uinta Mountains:

The Utah Triple Crown was first coined in 2001 when I did a one day ascent of all three of Utah's tallest peaks in a day, starting from an advanced base camp at Dollar Lake. The three peaks are King's Peak, South King's, and Gilbert Peak; in that order. The trip was covered by a local paper and over time has received a bit of attention by local peakbaggers. I never considered what I did a FA and I know of at least two other people who have come forward and said they had done it before me.
