Juhani Pallasmaa:

Snow is a material of inherent dualities: it is inviting and hostile, transient and impermanent yet moldable, it protects against cold but radiates coldness, it absorbs sound and emanates light. Snow suppresses shape and materiality and turns the landscape into a dream image.

One of my most powerful experiences of landscape is the all-white, treeless field landscape of northern Lapland, which undulates softly towards infinity, beyond the range of vision. An overcast sky eliminates all shadows and the snow blanket takes on the same dim whiteness, making the reading of the horizon line, and consequently, one's position in space, strangely ambiquous. As you are unable to read the fundamental distinction between earth and sky, the understanding of balance, stability and motion, distance and nearness, is lost. The senses are confused and the experience evokes hallucinatory images. One's sense of reality and self is altered.
