I’m fond of reminding people that the human genome contains some 20,000 genes, while a poplar tree boasts 45,000. What does it mean when the complexity of the human brain is governed by fewer genes than a block of wood? Perhaps only that when it comes to DNA, the traits of wisdom, stoicism and vigilance may be more hard-won than mobility; as it turns out, scientific research is now showing us that trees can learn and communicate through their roots via underground fungal networks—and not only with trees of their own species. Since the root-fungus connections function much like the neural networks of animals, skiing trees is like navigating through something akin to a large-scale communal brain.
In British Columbia, where I now live, not only do I still love skiing trees, but I also enjoy the myriad forms they take—from hunched snow ghosts to towering alabaster arrows of improbable symmetry. It would be easy to view such statuesque embodiments as living things that have simply checked out of daily existence for a bit, their weighted encasements of snow a measure of the force of winter. Certainly, the celebrated sauthor Lewis Carrol must have thought so when he wrote: I wonder if the snow loves the trees and fields, that it kisses them so gently? And then it covers them up snug, you know, with a white quilt; and perhaps it says “Go to sleep, darlings, till the summer comes again.
