On Friday, May 13, the National Park Service hosted a science forum to provide the results of several research projects commissioned by the Merced River Plan. These studies were intended expand the park’s existing knowledge of the Merced River's water quality, its free-flowing condition, and its Outstandingly Remarkable Values (those values that merit the river's designation as wild and scenic, pursuant to the Wild and Scenic Rivers Act).

Date: May 13, 2011
Time: 9am - 2pm (1-hour lunch break)

Vernal and Nevada Falls

In Yosemite Valley, dropping over 594-foot Nevada Fall and then 317-foot Vernal Fall, the Merced River creates what is known as the “Giant Staircase.” Such exemplary stair-step river morphology is characterized by a large variability in river movement and flow, from quiet pools to the dramatic drops of the waterfalls themselves.
