Mescalito is the pyramid-shaped formation splitting the Pine Creek Canyon within the Red Rock Canyon National Conservation Area (approximately 20 minutes driving time from downtown Las Vegas). From the approach trail, Mescalito looks like a miniature version of its near neighbor, Rainbow Mountain. Both share similarily colored characteristic rock bands - grayish lower portions and redish upper regions.
This FKT is for Pine Creek Canyon Trailhead->Mescalito Summit->PCC Trailhead, the route you choose up and down the Mescalito is up to you (feel free to include your Car-Summit time in your notes) there is an ammo box for a summit register at that top.
You can find various routes from 5.5 - 5.7 (or greater) on Mountain Project that will allow you to climb/scramble the rest of the way to the summit. Regardless this is an adventure climb full of hard scrambling no matter which way
You can also look through a class 3/4 descent (or maybe ascent too?) option on both Mountain Project and Summitpost.
Excited to see how ascent-descent routes get refined (new hybrids?) to optimize efficiency on both the Mescalito and the bushwhacky trails and washes below
