Elevation, Altitude, and Acute Mountain Sickness

Both SNARL and Valentine Camp are located at high elevation (between 7000-9000 feet above sea level).  If you are travelling here from lower elevations, you will likely notice shortness of breath and fatigue, and may experience headaches, nausea or sleeplessness.  Acute mountain sickness is caused by the reduced percentage of oxygen at this elevation.  Limit strenuous activity, limit alcohol consumption and get plenty of water and rest.  Most people feel better within a few days.
