SG,
Great Pics and looks like a fine trip!
After two runs up to the summit
on Scoots, I will not do another,
unless it's on that train or, in a
rental 4 wheeler,

.
The "road" is composed of a mini
version of those granite slag heaps
in your pics; just much smaller size
stone. You did the right thing taking
the train.
SG, You get better looking by the year!
