Factors Affecting Opening of Seasonal Campgrounds
Once the Tioga Road opens, crews begin working in campgrounds and other facilities to prepare them for opening. Before campgrounds can open, crews assess the condition of the campgrounds, remove hazard and fallen trees, make emergency road repairs, de-winterize restrooms, pump vault toilets, and turn on and test water systems. Additionally, sewer and utility systems often need repair each spring.
All this work also has to happen at visitor centers, offices, residences, and other facilities, as well. Opening offices and residences for staff are a high priority because campgrounds and other facilities need staff in order to operate.
As a result, campgrounds usually don't begin opening until at least two to four weeks after the Tioga Road opens.

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.
