About Yosemite

President Abraham Lincoln is credited with signing a bill in 1864 which granted about 60 square miles of the Yosemite Valley and the Mariposa Grove to the State of California. From there, renowned naturalist and conservationist John Muir helped to lead the creation of Yosemite National Park in 1890. Yosemite was added to the natural park system which had begun in 1872.

In 2009, Yosemite National Park received 3,866,970 visitors, which is the highest number of visitors since hitting the 4 million mark back in 1996.

Yosemite’s Waterfalls, Reseviors, Lake and Rivers

Yosemite Park is noted for its many waterfalls, including Yosemite Falls which at 2,425 feet is the tallest waterfall in North America. is home to countless waterfalls. The optimal time to view the various waterfalls is during the snow melt in the spring months. Peak runoff typically occurs in May or June, and some of the waterfalls are then completely dry by August. According to the nps.gov, other waterfalls include:

  • Upper Fall: 1,430 feet
  • Middle Cascade: 675 feet
  • Lower Fall: 320 feet
  • Bridalveil Fall: 620 feet
  • Ribbon Fall: 1,612 feet
  • Vernal Fall: 317 feet
  • Nevada Fall: 594 feet
  • Illilouette Fall: 370 feet
  • Silver Strand Fall: 1,170 feet
  • Sentinel Fall: 2,000 feet
  • Horsetail Fall: 1,000 feet

The park is also home to literally thousands of lakes. Finding the exact number of lakes and rivers of Yosemite is difficult, because many are seasonal and like the waterfalls, evaporate after a period of time. Furthermore, many of the lakes and rivers of Yosemite are located in the wilderness, and are only accessible to visitors by hiking to their locations. A map of the park can be used to identify both the locations, as well as the names, of many of the true lakes and reservoirs.
