The high grey-flannel fog of winter closed off the Salinas Valley from the sky and from all the rest of the world. On every side it sat like a lid on the mountains and made of the great valley a closed pot. On the broad, level land floor the gang plows bit deep and left the black earth shining like metal where the shares had cut. On the foothill ranches across the Salinas River, the yellow stubble fields seemed to be bathed in pale cold sunshine, but there was no sunshine in the valley now in December. The thick willow scrub along the river flamed with sharp and positive yellow leaves.
