At approximately 3:30 p.m. on Monday, March 22, 2010, the Yosemite
Emergency Dispatch Center received a call regarding a collapsed hiker on
the Upper Yosemite Fall Trail.  The hiker, a 17-year old student from
Upland, California, was on a hiking trip with the Yosemite Institute.  He
was with a group of approximately eight students, with several adult
chaperones and instructors.  This hike is a regular part of the curriculum
experienced by the students of the Yosemite Institute, a week-long
residential environmental education program.

The hiker collapsed near the summit of the Upper Yosemite Fall Trail.  The
trail is a strenuous, 3.5 mile hike that begins in Yosemite Valley.

Two Yosemite National Park Rangers were dispatched to the scene to assist
the hiker.  Once the Park Rangers reached the hiker, a California Highway
Patrol helicopter assisted in hoisting the injured hiker.  The young man
was then airlifted to the Children’s Hospital in Madera, California.

The cause of the hiker’s collapse is unknown.
