The Half Dome Cable Route hike runs from the valley floor to the top of the dome in 8.2 mi (13 km) (via the Mist Trail), with 4,800 ft (1,460 m) of elevation gain. The length and difficulty of the trail used to keep it less crowded than other park trails, but trail traffic grew to as many as 1,000 people a day, and about 50,000 per year, before ...
The popular Half Dome hike to the summit of Half Dome requires a permit whenever the cables are up (usually from Memorial Day weekend to Columbus Day). [133] A maximum of 300 hikers, selected by lottery, are permitted to advance beyond the base of the subdome each day, including 225 day hikers and 75 backpackers. [134]
The youngest Yosemite Valley pluton is the 87-million-year-old Half Dome granodiorite, which makes up most of the rock at Glacier Point, the Royal Arches, and its namesake, Half Dome. Half Dome from Washburn Point. For the last 30 million years, glaciers have periodically filled much of the valley.
The Half Dome cables are something I used to write about (and experience firsthand) with some frequency. In 2010, as a solution for overcrowding when permits were being considered, I suggested ...
The park limits the number of people who can climb Half Dome to 300 per day, a cap aimed, in part, at reducing gridlock on the cables. If you go without a permit, and get caught, there’s a $280 ...
Half Dome, a quartz monzonite monolith in Yosemite National Park and part of the Sierra Nevada Batholith. A batholith (from Ancient Greek bathos ' depth ' and lithos ' rock ') is a large mass of intrusive igneous rock (also called plutonic rock), larger than 100 km 2 (40 sq mi) in area, [1] that forms from cooled magma deep in the Earth's crust.
Hiking to the top of Half Dome in Yosemite requires traversing at least 14 miles while gaining 4,800 feet in elevation, an impressive feat for any adult — let alone one in his 90s.
Half Dome rises more than 4,737 ft (1,444 m) above the valley floor. 10 million years ago, vertical movement along the Sierra fault started to uplift the Sierra Nevada. [2] Subsequent tilting of the Sierra block and the resulting accelerated uplift of the Sierra Nevada increased the gradient of western-flowing streams. The streams consequently ...
