Greylock is actually the inspiration for Herman Melvilles "Moby Dick." There was a very relevant quote inscribed on a rock at the summit. It seemed very fitting for that cloudy day.
The inscription on the rock reads as follows:
"As the light increased
I discovered around me an ocean of mist,
which by chance reached up to exactly the base of the tower,
and shut out every vestige of the earth,
while I was left floating on this fragment
of the wreck of the world,
on my carved plank in cloudland;
a situation which required,
no aid from the imagination
to render it impressive.
Henry David Thoreau
