When a trail is cut to direct traffic in one direction but gravity pulls skiers in another, everyone gets sucked to the same area—the downhill border of the trail. This leaves a lane of scraped-off snow down the middle of the run and a berm of untidy harbor chop along the edges.
Because everyone succumbs to the pull of the fall line rather than follow the path of the trail, good snow often remains uphill. Learn to love the double fall line and its uphill spoils. You’ll have to work hard to resist gravity’s forces, but hold the high line and you’ll get the goods.
