Yosemite National Park at Yosemite, California

The spectacular landscape of Yosemite’s bald domes and deep valleys, of its crashing waterfalls and rarefied high country vistas took over 100 million years to create. The dramatic cliffs are made of granite, formed deep in the earth as molten rock which slowly cooled and solidified into massive stone megaliths. About sixty-five million years ago, the granite core of the Sierras Nevada mountains became exposed. Twenty-five million years ago, tectonic forces lifted and tilted the granite range and formed the tall Sierra Nevadas. Then the forces of water and ice began to shape the hard stone.

Enter the glaciers. Over the last two to three million years, ice fields and glaciers at times capped the high peaks and during ice ages, descended down the valleys to scour and change the landscape. Rivers had cut “v” shaped valleys, but the grinding of glaciers created “u” shaped ones with wide level floors filled with glacial sediment. Geologic time is writ large in the Yosemite Valley.

Human have also left their marks on the Yosemite landscape. The Ahwahneechee tribe of the Miwok Indians have lived in the Southern Sierras for perhaps 7,000 years. Moving from the deep canyons to high alpine meadows, the Ahwahneechee developed a hunter and gatherer life style suited for the high Sierras. Change came in the early 19th century with contact with Europeans-Americans. After the Gold Rush brought a flood of miners to the region, John Savage set up a camp in the foothills which was attacked by the tribe. In retaliation, a volunteer militia called the Mariposa Battalion fought and eventually defeated the Ahwahneechee. A lake in the high country where a major battle occurred was named after Ahwahneechee’s Chief Tenaya. Tenaya and his tribe were forcibly removed to a reservation near Fresno, but Congress did not accept any of the eighteen treaties made with Californian Indians in 1851 and 1852. Over the years, even though the U.S. government forcibly evicted the Ahwahneechee from the Yosemite Valley, tribal members still live in the area.

Some argue that Yosemite is our oldest park. Here’s why—President Lincoln, in 1864 in the midst of the Civil War, signed the Yosemite Land Grant, setting aside the Yosemite Valley as a nature reserve run by California. To be sure, Yellowstone became our first National Park in 1872, but Yosemite was our first protected place. Lincoln never visited Yosemite, but his legacy in protecting it place continues to thrill millions of people a year. Four years after Lincoln designated Yosemite as a nature reserve, John Muir arrived in the valley.

Already a world traveler, Muir fell in love with Yosemite—with its high mountains, the Granite Cliffs, the sequoia trees at Mariposa Grove, and the valley floor. In an essay for The Century magazine in 1890, he marveled about the beauties of Yosemite.

About the High Sierra, he wrote: “It seemed to me the Sierra should be called, not the Nevada or Snowy Range, but the Range of Light. And after ten years in the midst of it, rejoicing and wondering, seeing the glorious floods of light that fill it,-- the sunbursts of morning among the mountain peaks, the broad noonday radiance on the crystal rocks, the flush of the alpenglow, and the thousand dashing waterfalls with their marvelous abundance of irised spray,-- it still seems to me a range of light.”[1]

Concerning the Granite Cliffs, Muir exults: “The brow of El Capitan was decked with long streamers of snow-like hair, Cloud’s Rest was enveloped in drifting gossamer films, and the Half Dome loomed up in the garish light like some majestic living creature clad in the same gauzy, wind woven drapery, upward currents meeting overhead sometimes making it smoke like a volcano.”[2]

Muir glories in the big trees: “The majestic sequoia, too is here, the king of conifers, ‘the noblest of a noble race.’ All these colossal trees are as wonderful in the fineness of their beauty and proportions as in stature, growing together…. Here indeed is the tree-lover’s paradise, the woods, dry and wholesome, letting in the light in shimmering masses half sunshine, half shade, the air indescribably spicy and exhilarating, plushy fir boughs for beds, and cascades to sing us asleep as we gaze through the trees to the stars.”[3]

About the Yosemite Valley, he proclaims: “No temple made with hands can compare with the Yosemite. Every rock in its walls seems to glow with life. Some lean back in majestic repose; others, absolutely sheer or nearly so for thousands of feet, advance beyond their companions in thoughtful attitudes…. How softly these mountains are adorned… their feet set in groves and gay emerald meadows, their brows in the thin blue sky, a thousand flowers leaning confidingly against adamantine bosses, bathed in floods of booming water, floods of light while snow, clouds, winds, avalanches, shine and sing and wreathe about them as the years go by!”[4]

Rallying around such words, advocates for Yosemite found allies in Congress, and Yosemite became a National Park in 1892. But the battle was not totally won. To continue to protect the sacred places in the Sierras, in 1901 Muir published Our National Parks, and in 1903, President Teddy Roosevelt visited Yosemite. Muir kidnapped him for several days of camping out in the high country, to the chagrin of the gathered politicos who wanted to bend the president’s ear. Together, Roosevelt and Muir, under the stars around a campfire and hiking over the granite domes, laid the foundation for a conservation policy that protected some natural resources and preserved the shrinking wilderness.

The last chapter in Muir’s life ends in a preservation tragedy. At the north end of the Yosemite National Park lays the Hetch Hetchy Valley fed by the Tuolumne River.  The growing city of San Francisco coveted the water in that valley and after the Great Earthquake of 1906, argued and won the rights in 1913 to that liquid resource. With the rights, the city dammed the Hetch Hetchy and siphoned the water off to the Bay Area. Muir and the Sierra Club fought hard against this, and he died a year later, some say a broken man from the loss of this stunning part of a national park.

When I visited Yosemite, the Mariposa Grove of giant sequoias was closed to the public for rehabilitation. There are almost 500 of these largest living things on earth in the grove, which was included in the original grant created by Lincoln in 1864. J. Smeaton Chase, an Englishman, wrote this about Mariposa Grove: “As one stands in the dreamlike silence of these groves of ancient trees, the solemnity of their enormous age and size combine to produce a cathedral mood of quietude and receptiveness.”[5]

Since I couldn’t get to the sequoias in Yosemite, I went south to King’s Canyon to experience these Big Trees. Granted, redwoods are taller, but sequoias’ trunks are bigger, and those massive trunks retain their girth as the trees climb. In terms of actual living mass, sequoias have more wood than redwoods.

I arrived at the General Grant tree after a brisk walk from the nearby campground, late for a Ranger Amber’s talk. This is the second biggest tree in the world, with the General Sherman tree at Sequoia NP taking the honors. Between 1,600 and 1,800 years old, the General Grant sequoia takes twenty people holding hands to encircle its trunk and in a weird statistic, could hold more than 37,000,000 ping pong balls. Here’s some more stats on the General Grant: height = 268 feet (82 meters); circumference = 107 feet (33 meters); diameter = 40 feet (12 meters); and weight = 1,254 tons (1,325 metric tons).

A saving grace for all sequoias is that they burst into splinters when felled so they are unsuitable for lumber planks. Shingles, yes and also fence posts, but considering it takes so much effort to cut one down, the resultant wood is not worth the trouble.

At the end of her presentation, I talked with some rangers about my concerns concerning all the dead trees on the western slopes of the Sierras. I had read in a Los Angeles Times  story that Sunday that the U.S. Forest Service estimated the 20,000,000 trees in the Sierra Nevadas had died since October and 60,000,000 since 2010.[6] I asked if wild fires could sweep through the groves here, at Sequoia National Park, and at Yosemite, and destroy these majestic ancient beings. One of the rangers said: “Perhaps we are the last generation to see these monarchs of trees.” Shocked, I spent the rest of the afternoon wandering around this cathedral of giants.

Yosemite, Kings Canyon, and Sequoia National Parks are places of immense beauty and spirit. Granite megaliths, ancient trees, deep valleys, high alpine mountains, tall waterfalls, they establish the sacredness of wilderness and allow us to commune with natural wonder. They change, as Muir wrote, our perception of nature and the world around us. Without such parks and without the people who struggled and continue to work to preserve these places, we would be a lesser nation and people. Just ask the over 4,000,000 people who visited Yosemite in 2015 or the 300,000,000 who went to some unit in our NPS system last year. The parks transcend our differences and unites us around their natural and historical landscapes.
