Yukon sky sculptures...

"rows and floes of angel hair

and ice cream castles in the air

and feather canyons ev'rywhere

i've looked at clouds that way"

"i've looked at clouds from both sides now

from up and down, and still somehow

it's cloud illusions i recall

i really don't know clouds at all"

excerpts from "Both Sides Now"

composed by Joni Mitchell

...in Southern Tutchone cloud is

"k'uk"

...rain clouds are "sha k'uk" or "sha achal".
