First we should understand that Yosemite Valley, the shear-walled canyon everyone sees in the photographs with the waterfalls and ‘half-dome', are actually a very small part of Yosemite NP. There are popular areas outside of the valley such as a large conference area where they hold a popular jazz festival every year north of the valley. The popular Badger Pass ski resort lies just south of the canyon. Further south there are several large campgrounds spotted all the way down to the southern entrance at Wawona. Behind the valley in the high country is a wonderful camping area called Tuolumne Meadows located off one of the few highways over the Sierra to relatively remote eastern California and Nevada. Between these features are large areas of wilderness and lakes - it truly is a beautiful park and should be preserved to the extent possible.
Yosemite isn't the only park in the Sierra mountains. The northern most park, Lassen NP with its volcano and cinder cone and lava flows is actually in the Cascade range of mountains, not the Sierra. The reason they are considered different is because the Cascades are of volcanic origin and the Sierra are tectonic plate uplifting as the Pacific plate runs into the Continental plate. That is why there is a short steep climb of perhaps fifteen or twenty miles to the top ridge of the Sierra from the East while the West slope from the foothills is over sixty miles!
South of Yosemite are two more parks, Kings Canyon on the Kings river and Sequoia famous for its grove of Redwoods. Kings Canyon is a wider canyon but otherwise similar to Yosemite. It is much less developed with most accommodations outside of the canyon itself. It is well known in California, but doesn't have the miseries of the international crowd that Yosemite has. Actually there are many groves of Redwoods in the Sierra including all three NP's.
There are large groups of California ‘environmentalists' I consider to be young backpackers, who advocate removing all man-made artifacts from the entire Sierra including roads and access so that they can have the entire five hundred mile long wilderness all to themselves. The other side of the coin are the business people who want to clear-cut, pave and industrialize the mountains just as they have everywhere else.
I find it difficult to side with either extreme. However, regarding Yosemite Valley, I do agree with the extremists that virtually all evidence of urbanization should be removed from the valley including the $1,000 per night hotel and all of the little touristy shopping malls, grocery stores and even the campgrounds. I would allow a few probably high volume restaurants and snackbars to accomodate day visitors but eliminate all overnight accommodations including the workforce which has its own city within the canyon.
Presently access to the dead end valley other than by tour bus is by car - and in the summertime, it is bumper to bumper! I advocate limiting auto access to at best the winter season and requiring automotive traffic to park outside the valley where there are millions of acres of parkland for parking lots and hotels, off any of its three access roads (north, west and south) to say nothing of neighboring communities who would love to care for visitors.
Everyone on Earth should have the opportunity to experience Yosemite Valley which is so unique. So the park should provide that access by greatly expanding and improving the park's free mini-bus services, and other facilities designed primarily for pedestrian and bicycle traffic rather than the congestion, glut and smell of gas and diesel engines!
In other words, get the unnecessary machines and buildings out of the canyon and provide access for many more people - not fewer! Actually, I wish they'd even bring back the free roaming black bears which were ubiquitous when I first visited the place many years ago - the customers would love 'em!
Yellostone NP used to have free roaming black bears also. Today, all you see are bison - it just ain't the same.
So, as you can see when you read the following article, that I don't agree with either extreme - and I'm not certain that Yosemite Valley's problems relate to other parks such as Yellowstone which is open and vast or most certainly the Grand Canyon near where I now live.
Yosemite suit could affect park access
By GARANCE BURKE, Associated Press Writer
YOSEMITE NATIONAL PARK, Calif. - The plunging waterfalls and soaring crags chiseled by the Merced River draw millions of visitors each year, but the crowds are precisely what threatens the waterway and the park.
Efforts to safeguard the Merced have spawned a court battle over the future of development in Yosemite National Park's most popular stretch. The case may come down to the challenge facing all of America's parks: Should they remain open to everyone, or should access be limited in the interest of protecting them?
In November, a federal judge barred crews from finishing $60 million in construction projects in Yosemite Valley, siding with a small group of environmentalists who sued the federal government, saying further commercial development would bring greater numbers of visitors, thus threatening the Merced's fragile ecosystem.
"The park's plans for commercialization could damage Yosemite for future generations," said Bridget Kerr, a member of Friends of Yosemite Valley, one of two local environmental groups that filed the suit.
The government is appealing, fearing the ruling could force the National Park Service to limit the number of people allowed into Yosemite each day, a precedent it doesn't want to see echoed in other parks.
"I don't think we've ever had a ruling with these kind of implications," said Kerri Cahill, a Denver-based planner for the park service. "It's going to have a direct influence on the public who care about these places."
The case has Yosemite's most loyal advocates sharply divided over how to balance preservation with access to public lands. Even environmentalists can't agree on how to minimize the human footprint — some believe cars should be kept out entirely; others say visitors should have to make reservations in advance.
