We have arrived at Lassen Volcanic National Park.

I climbed Lassen Peak and saw the crater from the 1914 eruption.
American hiking trails are well-maintained, so they are easy to walk on.
Elevation of the trailhead: 2590m
Elevation of the summit: 3190m
Elevation difference: 600m
One way: 2.5 miles (4km)
Going up: about 1 hour 15 minutes
Going down: about 45 minutes

If I were to describe this place in a "Final Fantasy" style:
It is a place where the "Courage" crystal sleeps.
By the way, the entire Sedona area is the "Justice" crystal.
Mount Shasta in Northern California is the "Hope" crystal.
