'By the time dawn was coming we had scraped two peepholes in the frost on the panes; and we stood quiet to watch the winter sunrise. The radiant peaks of the Driftwoods, cut like white icing into pinnacles and rims against the apple-green sky, were brushed with pink, that, even as we watched, spread down and down and turned to gold. Rays of the rising sun, coming between the pointed firs of the east shore, stretched straight across the white lake, and as they touched it huge crystals, formed by the intense cold, burst into sparkling, scintillating light. The snow-bowed trees of the south and west shores were hung with diamonds; and finally the willows, around our cabin, were decked with jewels as large as robins' eggs that flashed red and green and blue. No Christmas trees decorated by human hands were ever so exquisite as the frosted trees of this northern forest. The sky turned to deep, deep blue, and the white world burst into dazzling, dancing colors as the sun topped the forest. The dippers, undismayed by a cold that froze dumb all other living things, broke into their joyous tinkling melody by the open water patch below the bank. And our first Christmas Day in the wilderness was upon us.'
This is from Theodora Stanwell-Fletcher's account of her months studying plants and animals in north-central British Columbia, Driftwood Valley (1947). You can read a fuller extract in Lorraine Anderson's Sisters of the Earth anthology.
