Route: Lost Mine Trail (Big Bend NP, TX)

Route is an out and back with a 2.34 mile accent and 2.34 mile descent that starts at the trailhead on partial pavement. You immediately start climbing on the route right from the trailhead and the pavement turns to trail shortly after .05 of a mile and the accent turns into switchbacks around 1.3 miles for almost half a mile. You eventually reach the lost mine summit as it opens up near the top at 2.34 miles. The other 2.34 back down is the hard part as you try to maintain speed and not fall.
