Natural Selection will weed the week out of the mountain biking population.
Natural Selection, found on the far end of the mountain off of the Chupacabara trail, is a true double black diamond trail! The descent begins with some flat ladder bridges leading to rolls down a series of fantastically-steep rock features.
A series of these features helps get you warmed up before the trail funnels into its marquee feature: a triple-piece wooden hit requiring you to nail a gap jump onto an elevated wooden bridge that's about four feet in the air, drop off the bridge, then roll into a fairly substantial wooden booter gap jump to finish.
There's no real ride around to speak of on the marquee feature on Natural Selection. If you don't want to hit two mandatory gaps and a mandatory drop, you'll be forced to walk your bike around this section. If you decide to hit this feature, it requires total commitment: this trail has broken more than one collarbone. Proceed with caution.
The trail finishes fast, with a few more fun wooden features before spilling out at the bottom of the mountain. Written by Greg Heil
