Here the first winter sleets and snows fall and lie, and here the spring frost lingers last unthawed.
"Jude the Obscure" by Thomas Hardy
Month after month have I gazed on the white monotony of unthawing snow.
"Donahoe's Magazine, Volume 15, No. 2, February 1886" by Various
In hollows where the sun was lost
Unthawed still lay the shining snow,
And on the rugged ground the frost
In slender spears did grow.
"Under One Blanket" by James Barron Hope
