Rising 14,409 feet above sea level, Mount Rainier towers so far above Seattle that a person can forecast the day’s weather by it. When the most glaciated peak in the entire continental U.S. is in clear view, the day holds pleasant temperatures and dry skies. If clouds obscure its lofty flanks, settle in for a typical Seattle day- drizzly and bone-chilling gray. In a similar way, Mt. Rainier offers those who would climb it unsurpassed opportunities to assess the human condition.
