Freeze and Thaw

Water and ice

In the depths of winter, the height of the season, the weather often follows a rollercoaster cycle: freeze, thaw, and freeze again. The January thaw is a recognized meteorological phenomenon around here. This year we’ve had several thaws, with stretches of single-digit nights between them.

The climate here in the middle of the continent depends on the weaving of cycles thousands of miles away. Mild air from the Pacific rolls in regularly. Sometimes it brings rain or wet snow. It also traps Arctic air in the north, building up until it looms over Canada like a glacier. Outbreaks of polar cold come roaring down across the plains. Road crews and TV weather forecasters shift into high gear.

Moss and snow
After snow, the warming air melts the earth into mud. When the deep freeze starts again, dirt turns solid. Deer tracks are set in stone. With the next thaw, the soil becomes powdery earthbound dust. This is the pattern that transforms rock into topsoil, crack by tiny crack. Gaia recreates herself each winter, with each grain of earth.

I walk in the woods every chance I get. The rare 60-degree days are gifts from spring, but I walk farther on cloudy days that never get above 40. My world is transparent in winter. I can see through the trees to the road at the foot of the hill, a neighbor’s barn, the bright surface of a lake in the valley.

Hickory bud
Hickory and oak trees make gray buds. Red twigs brighten at the tips of dogwood trees. Black clusters form where seedpods attach to redbud branches. This year the first snowdrops bloomed on Twelfth Night. The woods are getting ready.

A Scottish legend says that the Goddess Brighid grows old and bent and gray as the rocky hills with the season. At the start of February she strikes a stone with her staff and releases a flowing spring. She drinks the living water and becomes young again, as lambs begin to be born and flowers spring from the ground.

In the next thaw, I will dig a little hard soil from my garden and put it in a pot. I will water it and set it beside my wood stove. As it warms with the year, we will move toward spring.
