"Rocky mountains suite" by John Denver Album: Farewell Andromeda (1973)

Up in a meadow in Jasper Alberta
Two men and four ponies on a long lonesome ride
To see the high country and learn of her people
The ways that they lived there the ways that they died

And one is a teacher one a beginner
Just wanting to be there and wanting to know
And together they're trying to tell us a story
That should have been listened to long long ago

Now the life in the mountains is living in danger
From too many people too many machines
And the time is upon us today is forever
Tomorrow is just one of yesterday's dreams

Cold nights in Canada and icy blue winds
The man and the mountains are brothers again
Clear waters are laughing they sing to the sky
The Rockies are living they never will die

Up in a meadow in Jasper Alberta
Two men and four ponies on a long lonesome ride

An hymn for the mountains and their wilderness, but there is also a warning for the dangers by touristic development, construction of accomodations and presence of too much people, pressures that sensitive mountainous ecosystems can't withstand.

We read about this song in cdciao:

Rocky Mountain Suite (cold nights in Canada) is a warning of the danger of the ever-expanding population, urbanisation and industrialisation. It was written for a documentary in which John and Canadian Mounty, Tommy Tompkins went in search of the lost herds of bighorn sheep, “living in danger from too many people, too many machines”. Rocky Mountain relays a similar message by emphasizing the natural qualities of the mountains “more people, more scars upon the land”
