The air temperature feels not much above freezing, pinching our faces as we hit the trail just after 8 a.m. on our second day of backpacking in Glacier National Park. The still, glassy water of Elizabeth Lake captures a razor-sharp, upside-down reflection of the jagged mountains flanking it; only the upper slopes of the peaks above Elizabeth’s western shore catch the early sunlight on this September morning. We pause occasionally on the strip of sandy beach along the lakeshore just to gawk at our surroundings.
Then we hear it.
