Conditions on the Grand Canyon’s Grandview Trail were—as a ranger warned us when we picked up our permit—“treacherous” for our late-March backpacking trip. Hard ice and frozen snow covered the trail’s uppermost couple of miles, where you frequently traverse sloping ledges a foot or two wide, with huge drop-offs. “Microspikes are mandatory,” the ranger told us, and he was right. Without them, we’d have risked becoming tomorrow’s news—or, more likely, have aborted our four-day trip.
