Safety Tips for Rocky Mountain
Altitude sickness can hit at 8,000+ ft — take 2 days to acclimatize
Get above treeline before noon to avoid lightning — storms hit fast and violently
Hypothermia risk even in summer — temperatures can drop 30°F in an hour
Elk rut in September — bull elk are aggressive near trails
