I just saw National Parks maps in PDF format for sale here. A quick glance at the sample Acadia National Park map was enough to determine that those are in fact the excellent maps produced and distributed by the National Park Service.

You may not be aware of that, but everything produced by the US government is in the public domain. This has been the case for a while. To digress a bit, the government commissioned (“work for hire”, paid with taxpayer dollars) the landmark photographic survey of the Farm Security Administration in the thirties, which included images by photographers such as Walker Evans and Dorothea Lange. All the resulting images are public domain, and many can be seen and downloaded here.

Back to the parks, if you go to the NPS page for Acadia, and click on “View Map”, you’ll get access to exactly the same file. Now, this viewer is nice, but maybe you’d like to download a PDF for off-line use ? I didn’t see any way to do that from the Acadia page.

Here is a tip for my readers. Many of the NPS documents are available from the little known Harpers Ferry Center site. For instance, the maps can be found nps.gov/carto. Just click on a state (for example Maine), and you will be given links to full size, downloadable PDF maps (if the “Adobe Acrobat PDF” link doesn’t work, be sure to try the “Alternate direct link”).

Now, don’t get me wrong. There is nothing wrong with repackaging in a more convenient form, and reselling data which in itself is available for free. To begin with, that’s what the USGS was doing by selling to you maps on paper. The information was free, but not the medium. To download all the maps manually will take a little more time. But I thought you’d like to know it can be done.

Looking for topographic maps instead ? The USGS is phasing out the 7.5-minute (1:24000) paper maps, and has set-up a new site US Topo, where the updated maps can be downloaded, all for free. That’s a serious number of files ! If this overwhelms you, National Geographic, amongst others, has been selling those on CD for a while.

I’ve posted new images of Black Canyon of the Gunnison National Park, taken during a trip in May 2009.

When I first visited Black Canyon of the Gunnison National Park, I limited my explorations to the North Rim. Although the relatively recent park doesn’t see many visitors, the North Rim is even more uncrowded, and it offers more unique perspectives than the South Rim, including the Narrows viewpoint, Exclamation point, and the North Vista Trail. The Black Canyon is one of the rare canyons that are more deep than wide. At the Chasm viewpoint, you are only about 1000 feet from the other rim, yet it takes a couple of hours by car, which explain the lesser visitation of the North Rim.

For the second visit, I spent all my time on the South Rim for the sake of completeness, which confirmed my preference for the North Rim as my research had indicated before. I was tempted to hike down to the river again, but the clouds looked ominous. I was glad I did not do so as torrential rainstorm struck in the afternoon. When I took the third image below, it was pouring, but instead of scrambing on steep and treachery terrain, I was photographing next to the road, almost from my car. That image was with the tripod set below the raised hatch of my station-wagon. On a large version, you can see every leaf glistening with water.

Joshua Tree National Park lies at the convergence of two deserts, the Mojave and the Colorado. Joshua trees and granite boulders characterize the windy high Mojave Desert, while at the Colorado Desert’s lower elevations, cactus and native California palm trees thrive among sandy washes occasionally flooded by unpredictable torrents.

The Cholla Cactus garden lies right at the transition between the two deserts, next to the Pinto Basin road that crosses the park north to south, about 10 miles south of the junction with Park boulevard (the closest campground is White Tank). Park at the designated pull-out, and stroll the nature trail.

The Cholla Cactus garden features the densest patch of the strange Cholla Cactus that I have seen so far. The scientific name of the species of Cholla that grows in the garden is Opuntia bigelovii, but it is often called Teddy Bear Cholla or Jumping Cholla. The joints break off very easily after being only slightly bumped. New cactus start growing right from the broken-off joints, so that the garden continues to renew itself.

The fuzzy-looking (hence “Teddy Bear”) cactus can be photographed successfully under a range of conditions, but my favorite is a backlit low light that makes the spines glow. Sunrise is preferable to sunset because the sun rises over lower distant mountains across the Pinto Basin, whereas it would set over the much closer and higher Hexie Mountains.

I inadvertently brushed against a Cholla Cactus while I was looking for a good viewpoint during the predawn darkness. The result was that I couldn’t dislodge it with my bare hand for fear of getting my fingers stuck as well. A beautiful sunrise below the clouds kept me in the Cholla Cactus Garden, with a cactus clenching onto my behind, until the light was well over. I then strolled back to the car to tease the spiny thing out with pliers.

I recommend that you don’t forget to take pliers as part of your kit. Without them, the barbed spines can easily remain embedded in the skin, causing significant discomfort. They are not called “Jumping Cholla” for nothing.

I’ve posted new images of Saguaro National Park, taken during a trip in May 2009.

This was my third trip to Saguaro National Park, made expressly to capture the Saguaro cactus flowers. Those blooms may be the ultimate desert flowers. Their short life is unique: they open at night, and will close permanently during the next day, often in the morning if the day is sunny. The bloom, large, waxy, and very flagrant, has been adopted by Arizona as its official state flower. By the way, did you know that the saguaro cactus is a protected species through Arizona ? It is illegal to harm one. A permit is needed to remove a Saguaro cactus, even from your own backyard.

The Saguaro cactus blooms mostly in May and June. The first time I visited was in early April. The weather was great, but the saguaro blooms were very sparse. After much exploring, I managed to find a few, and photographed close-ups, but I wanted to see more of them, and depict them in the landscape. My second visit was in March, timed for the annual flowers, which carpeted the desert floor on that an El Nino year. However, this was clearly too early for the Saguaro flowers. On this third visit, the weather was unusually cloudy for Arizona, but the flowers were there !

Photographing them presents a challenge, since they grow on top of the saguaros, which can reach dozens of feet in height for a mature cactus. I looked for a position above them, on steep slopes, and for specimen with arms curving downwards.

Zion National Park has sometimes been called a “Yosemite in color”. The comparison is apt, since both share a great variety of beauty, both in large scenery and intimate details. Like Yosemite, Zion features at its heart a narrow valley with a beautiful river and vegetation, flanked by sheer cliffs and rock towers.

However, unlike Yosemite, the Zion valley hasn’t been carved by glaciers, but instead by the Virgin River. The rock isn’t granite, but sandstone. This soft rock has allowed the river to gouge the Narrows, a deep gorge which in some places is only a dozen of feet wide, between walls that reach a thousand of feet high and spread only slightly to reveal a narrow sliver of sky. Hiking into the Narrows is one of the most unique experiences to be had in a national park, as you are most of the time wading in the river itself.

When to go is decided by a combination of factors. You’ll want to avoid high water flow (spring run-off from March to late May, later in years of heavy snowfall), flash flood danger (at its highest during the monsoon season in summer – if there is a risk of thunderstorm, the Park service will close the Narrows to hiking), high traffic (during the summer), and freezing temperatures (in winter).

My preferred time of the year to hike the Narrows would be in the late autumn. The small maple trees growing on the riverbanks turn shades of yellow and orange. The water level is at its lowest, which makes it easier to carry camera equipment. The cold water temperatures discourage crowds, which are much more abundant in the spring, and at their peak in the summer.

The key is to equip yourself appropriately by renting from an outfitter in Springsdale. At a minimum, canyoneering shoes will help protect your feet from the rocks that litter the riverbed, as well as provide you enough traction to avoid slipping – and falling in the water with your camera equipment – while neoprene socks will keep your wet feet warm. If the temperatures are cold, a dry suit would be useful as well, but don’t worry, as the outfitter will advise you. If you are going to be in the canyon all day, take a warm jacket for the return trip, as temperatures dip in late afternoon.

You also need something to help with your balance, as well as prob the river depth, since the water is not clear enough for you to see the bottom. At the start of the wet part of the hike, there is usually a stockpile of sticks that you can borrow, but a pair of hiking poles is more efficient. Or you could just use your extended tripod. It gets heavy in your hands, but you’d lighten your pack and be able to set-up faster.

The hike starts at the end of Zion Canyon with a mile-long surfaced trail called the River Walk, which in itself is quite nice. At the end of that trail almost everyone turns around, but you will simply step down into the river to continue.

During the fall, in the lower part of the Narrows, the water is between ankle and knee-high, and you can sometimes walk on the edge of the stream, but a few miles up, you may encounter pools that are waist-high.

You could hike up the Narrows for two days (although usually overnight trips are done in the opposite direction, down river, using a shuttle), but to see the narrowest part of the canyon, you just have to go a bit beyond the junction with the Orderville canyon, which takes about 1 hour and half to reach from the end of the Riverside Walk. Another hour and half makes it possible to reach the other end of the narrowest part. You should start as early as you can, so that you reach the narrowest part by mid-day, when there is more light. At the least, you should hike about half an hour to the Mystery Falls.

Like in many locations in the South West, you will be photographing in reflected light, avoiding directly lit spots (that produce excessive contrast). Even by mid-day, it can get quite dark in the canyon, especially during the fall. You will also be making many compositions with moving water, for which a slow shutter speed can be desirable. For both those reasons, a tripod is essential. It is wise to pack your equipment so that a fall in the water would not ruin it. A specialized water proof photo backpack would be handy, although I just used ziplock bags inside a regular backpack. In many places, the canyon exposes a small riverbank where you can set up your gear.

Missed Ken Burns’ “The National Parks: America’s Best Idea” last fall? The series returns to prime time this winter, with the first episode airing this Wednesday, Jan 27 on PBS, and then appearing on consecutive Wednesdays through March 3. For local times, check the PBS site. Each episode will be also available for online viewing for a week, following its airing. Note that the DVDs have now been released, if you prefer to watch at your own pace. Ken likes to joke that the series is a great excuse to upgrade to HDTV.

I have written before about my role in the movie, but did not provide a clip. Here it is, from Episode 4, considered to be the masterpiece of the series by this reviewer.

This appearance was short, but there were only a few other living characters (as opposed to commentators) and the movie was seen by more than 30 million people. I am often asked, what impact did the newfound fame have?

Not much happened on the web (where I conduct my business exclusively). Immediately after the broadcast, just a few dozens of people added me as their friend on Facebook, or followed me on Twitter. At first, I couldn’t even see any difference in web traffic in terms of numbers of visitors, although I could see that they were more engaged from the number of page views. It’s only when I used the beta Intelligence function of Google Analytics – which makes it possible to monitor events by analyzing logs in a very sophisticated way – that I could quantify the number of new visitors from the first broadcast: about a thousand, a number drowned in the usual thirty thousand daily visitors. Besides a number of queries for my National Parks book (which doesn’t exist yet), impact on the business was minimal.

However, from October to this date, I went to five gatherings: a group show opening in Thousand Oaks, a diving trip to the Channel Islands, a company function for a client in Walnut Creek, a gallery opening for another artist (Jock Sturges) in San Francisco, and a wedding in Anaheim. In each of those instances, I was surprised that one or more persons recognized me from the movie.

The most pleasant, and unexpected surprise is that I was able to reconnect with several old friends with whom I hadn’t been in touch for sometimes more than a decade, as they emailed me upon watching the series.

The Grand Canyon defines immensity. It is so vast that the Colorado River, which has carved it, is a distant sight from most overlooks. The only place in Grand Canyon National Park where you can look straight down to the Colorado River from the rim is Toroweap. You will stand at the edge of a shear cliff with a 3000 ft drop with no railings.

While during the summer the overlooks on the South Rim can get crowded well before sunrise, at Toroweap, there is a chance you’ll have the view for yourself, as Toroweap is within the Tuweep Wilderness, one of the most remote areas in the United States. From the North Rim, the driving time is almost four hours.

Toroweap is reached by driving CR 109, a 60+ mile graded, unpaved road that starts 9 miles west of Fredonia on hwy 389. Stay on the most heavily-traveled branch, and you’ll arrive to a ranger station. After 5 more easy miles, the road crosses solid slickrock for the last 2 miles. With careful driving, a normal car can pass that section (I drove a Subaru Legacy), but watch for sharp edges that can cause tire punctures. When you reach the edge of the canyon, the road loops in a circle. You’ll be only a hundred feet from the rim.

One of the most spectacular locations for a sunrise in the Park, the classic view looks northeast as the rising sun illuminates the vertiginous cliff below. For a change, I am displaying a photo of myself, taken with a programmable self-timer. Had my wife been with me, she wouldn’t have let me even think about doing that. Views in both directions are interesting and should also be tried at sunset. You would be camping at a nice, but primitive site just fifty feet from the rim. Do not wander in the dark !

Tired of seeing images of the US National Parks ? Ten of my images from India are on display in the lobby of the Balboa Theater, in the Richmond District of San Francisco, until early March.

It is clearly not possible to portray a multi-religious, multi-lingual, multi-ethic, and multi-cultural country of over one billion people with so few images, but I have tried to create a good mix with a few themes. Each of the images is from a different site in the country, visited during just 12 days of travel in 2007.

Over the course of the next month and half, I will continue posting new images of Western National Parks. Those are of course already well covered on this site, so each update will be rather small, covering either areas for which I had not published images before, or picturing areas with existing images in new light.

Today’s update is Death Valley National Park, with images taken during a family visit during which we drove down Titus Canyon, stopped at Scotty’s Castle, and then made it to the Racetrack.

Contrary to some reports of a rough road, we had no difficulty with our Toyoto Sienna minivan, taking only about one hour and fifteen minutes from Ubehebe Crater to the Racetrack. The vibrations from the washboard are worse if you drive slowly. I had been to the place four times before, but this was the first family visit to the Racetrack, where the infant strollers proved very convenient ! It was great getting others to see for themselves this unique phenomenon. With more people to spread out and explore, we found more complex networks of moving stone tracks than I had seen before. Since the family did not want to drive back by dark, the light of the Racetrack was not the best, but on the other hand, I was able to photograph Ubehebe Crater at dusk, which as often is the case with volcanic landscapes, turned out more interesting than the daytime images.
