Avalanche Forecast - Presidential Range

  • Alpine: Low
  • Treeline: Low
  • Below Treeline: Low

<p>Avalanches are unlikely, but the refrozen snow surface demands a mountaineering mindset. Crampons, an ice axe, and a helmet are necessary in steep terrain where a fall could have serious consequences. Springtime hazards have also emerged, including open holes, and undermined snow.</p>
