'A certain coolness from him'

Panther Mountain in the Adirondacks

“Besides the wear of iron wagon wheels
The ledges show lines ruled southeast-northwest,
The chisel work of an enormous Glacier
That braced his feet against the Arctic Pole.
You must not mind a certain coolness from him
Still said to haunt this side of Panther Mountain.’’

— From “Directive,’’ by Robert Frost (1874-1963), who lived much of his last decades on the western slope of the Green Mountains; the Panther Mountain probably referred to here is in New York state.
