Morning crossing: manageable.
Afternoon crossing: waist deep.
We’re now on Day 5 of the prolonged thaw in the White Mountains, and the snowpack is disappearing quickly. All of that melting snow has to go somewhere, and right now it’s pouring into mountain streams and drainages.
This photo was shared with us and shows a crossing that had become waist deep by the afternoon. With the rapid snowmelt happening right now, water levels in mountain streams can change dramatically over the course of a warm day. A crossing that feels manageable in the morning may look very different by the time you return to it later in the afternoon.
This is one of the most common hazards we see during spring melt. A crossing that feels easy on the way in can become fast, cold, and difficult—or even impossible—on the way out.
As temperatures rise throughout the day, snowmelt increases and streams can swell quickly. What starts as a rock hop or shallow crossing in the morning can become thigh or waist deep by late afternoon, especially in the higher elevations where the snowpack is still melting rapidly.
This time of year, choosing routes that avoid unbridged stream crossings is often the safest option.
If your planned hike involves multiple crossings without structural bridges, it may be worth saving that route for later in the season.
A few things to keep in mind during spring thaw:
• Water levels often rise significantly throughout the day
• Cold water and strong current can quickly lead to loss of footing or hypothermia
• Conditions on the way out may be very different from the way in
• Always be willing to turn around if a crossing becomes unsafe
Getting stranded on the wrong side of a swollen stream is a surprisingly common problem this time of year.
Plan accordingly, choose routes wisely, and remember — the hike isn’t over until you’re safely back at the trailhead.
Stay safe out there.
