As our world changes, I’m grieving my old friends cross-country skiing (on natural snow) and the subnivean zone, while still making a point to appreciate new delights. I can’t even count how many times I’ve looked at the frozen surface of a North Shore river and wanted to walk the whimsical ice formations up through bedrock canyons. But on past visits the snow was too deep, the wind chill too brutally cold, or the skiing too good to choose that adventure.  This past weekend, conditions were finally perfect!
