A Brief History of Yosemite

Yosemite’s story begins with Indigenous tribes Southern Sierra Miwok, Paiute who lived here for 4,000 years, hunting and gathering Ahwahnee was their valley name rangers share their tales.

The Civilian Conservation Corps built trails Glacier Point Road in the 1930s Hetch Hetchy Dam drowned a valley in 1913, a lingering scar rock climbing boomed post-WWII El Cap’s Nose a legend 1950s saw crowds surge Ahwahnee Hotel shines from 1927.

Today, Yosemite melds Native roots, Muir’s vision, and modern marvel its cliffs a testament to time, enduring amid tourism and climate shifts.

El Capitan’s monolith 3,000 feet looms sheer intrusions cooled underground exfoliation rounds domes Glacier Point stuns at 7,214 feet.

Waterfalls Vernal, Nevada plunge from hanging valleys rivers like the Merced erode meadows like Tuolumne bloom above 8,000 feet sequoias in Mariposa Grove tower 2,000 years old earthquakes jolt 1857’s felt here against cliffs and cascades, Yosemite’s a frozen dance of ice and stone.
