It is important for climbers of any Cascade summit to be aware of a few things:
Climbing parties should use good judgment and take special care of weaker members and novice climbers (Always think Safety is Item Number One)
Be prepared for treacherous slopes (steep, slick, with dangerous runouts), especially on descent, going from the basin at timberline to the crest of Monitor Ridge
Before climbing, gain knowledge of competent use of an ice axe or ski poles on all snow slopes, and the ability to self-arrest a fall under any conditions
Be aware of receding snow on current glissade paths higher on the Mountain, exposing rock hazards
Stay well back from cornices that still remain along the summit rim
Prepare for warming temperatures demanding that climbers carry three liters of water at a minimum
Know and use proper footwear, clothing, sun protection and sunglasses!
