Norm’s Stargazer Arch

NABS is pleased to announce that we have selected an arch to name in honor of the memory of long-time member and SPAN publisher, Norm Self, who passed away earlier this year. Norm and his wife, Linda, lived in El Centro, CA for many years and Norm delighted in taking numerous friends out to see the arches on “Three-Arch Hill” in Gavilan Wash west of Picacho State Recreation Area in eastern Imperial County, CA. This area had special meaning to Norm and Linda and that played a role in selecting one of these arches to honor Norm.

The three arches located there have been unofficially referred to as Hag’s Tooth (CA-146), Gavilan Wash Arch (CA-145), and Eye of the Hawk (CA-144). “Hag’s Tooth” was aptly used for obvious reasons, and Gavilan Wash Arch was too small (5-foot span), so we chose Eye of the Hawk to honor Norm. Therefore, California arch NABSQNO 11S-707583-3657511 will hereafter be referred to by NABS as Norm’s Stargazer Arch (“Stargazer” was Norm’s old CB handle). Eye of the Hawk (“Gavilan” is Spanish for “hawk”) will be retained as an alternate designation. Of the three arches, Norm’s Stargazer Arch is the largest, northernmost, and highest elevation. It has a span of 20 feet and a height of 7 feet. NABS is planning a visit to these arches at the end of our next Rally.

NABS Spring Rally, May 2015, Escalante, Utah

The Natural Arch and Bridge Society Spring 2015 Arch Rally was held in Escalante, Utah, and had about 40 members in attendance.  It was great fun with several trips daily.  Here are some photos from the Rally (hover for caption; click for slide show).

NABS Collaborates with Red Bull

Your webmaster and Blog editor David Brandt-Erichsen got a new job as Natural Arch Consultant when NABS was asked by Red Bull Adventure for assistance in compiling a collection of arch photos. Although it was one-time only and there was no pay, it’s a start!

The NABS Board and a few other members joined in on the fun of making suggestions, and two of our intrepid international arch hunters, Ray Millar and Gunter Welz, actually got paid for some photos.

The Red Bull editors of course made the final selection. The article was published July 28:

10 natural bridges that’ll give you wanderlust

Since it’s hard to stop at just 10, here are three more that the editors looked at to further whet your appetite:

Partial Collapse of Ring Arch in Arches National Park

By Terry Miraglia

These photos show a dramatic change in the appearance of Ring Arch in Courthouse Wash in Arches National Park. Sometime between April 29 and October 7, 2014, a significant portion of the arch collapsed, leaving the arch very much thinner and looking quite delicate.

As the photos show, the left abutment remains intact, but shortly beyond, a large amount of rock including a portion of the right abutment has fallen. The arc of rock that remains shows no fractures in the photos, but it showed no fractures in the earlier photos either. Standing under the arch, it appears as though much of the lower right front of the span has fallen.

Ring Arch may be seen almost directly west from the park road from a long pullout on the west side of the road (NABSQNO 12S-621729-4278463) about 0.15 miles southwest of the center of the Courthouse Wash Bridge. Binoculars will help, as the arch is about 1.3 miles from the road and the arch location is not obvious.

There is no established trail to Ring Arch. Walking directly to it from the park road view is not recommended since it is difficult to avoid disturbing sensitive desert soils. It’s also unpleasant to deal with the stickers in dense patches of Russian thistle and several tumbleweed-filled drainages. A better route starts on a use trail at the parking area on the northwest side of Courthouse Wash (12-622006- 4278791).

Ring Arch is tucked in a northeastward facing alcove and has morning sun. Courthouse Wash can have standing water, serious mud, and voracious seasonal biting insects. Walks taken after a dry spell and when insect populations are low are recommended. If you are good at finding use trails and return the way you came, your round-trip walk will be about 4.0 miles. This is a wonderfully pristine area, so stay in drainages when possible and do your best to insure there is only one narrow footpath leading to the arch.

Ring Arch is a very old pothole type natural arch, which has formed in the Slick Rock Member of Entrada Sandstone. The Slick Rock Member was deposited in tidal mudflats, beaches, and sand dunes during the Middle Jurassic period between 180 and 140 million years ago.

Sources agree that Harry Reed, a Moab photographer and custodian of what was then Arches National Monument, first reported Ring Arch in 1940. Slim Mabery, a former district ranger at the monument, named the arch in 1961. The name comes from the shape of the arch. According to the World Arch Database, Ring Arch’s span is 45’ with a height of 39’. After the recent rockfall, the arch may be marginally taller.

Making Money from Arches

No, the Natural Arch and Bridge Society does not make money from arches.

But some governments do.

The United States Mint released an Arches National Park quarter in 2014 as part of its America the Beautiful Quarters Program, featuring Delicate Arch. You can buy a 100-coin bag of these from the U. S. Mint ($25 face value) but it will set you back $40 with shipping. [UPDATE 2016: Not any more, but you can get a pack of 3 for $9.95 + $4.95 shipping.]

Money: Arches National Park Quarter

NABS member Daniel Putelat has the following coins in his collection.  Quebec released a coin featuring Le Rocher Percé:

Money: Le Rocher Perce Canada

He also has in his collection this 2015 Monnaie de Paris (Money of Paris) featuring Pont d’Arc:

Money: Pont D'Arc France

Daniel also has in his collection these Monnaie de Paris featuring Etretat:

Arch Collapse at Point Reyes Kills One

One person died and another was critically injured just before 6 p.m. on Saturday, March 21 when the bluff above Arch Rock (V21-12, NABSQNO 10S-516381-4204424) collapsed when the two hikers were standing on it. The arch is at the end of the Bear Valley Trail in Point Reyes National Seashore, California. The pair fell about 70 feet and were covered by the falling rocks and debris. The collapse of the bluff came about two days after the National Park Service had posted warning signs about the cliff becoming weak from cracks and partial collapses.

Arch rock is a meander type natural bridge where Clear Creek had cut through the narrow peninsula which had connected Miller Point to the mainland as shown in the photo below, looking back from Miller Point across the top of the arch before the collapse.

The post-collapse photo below shows that the arch actually survived the collapse of the bluff above it, a testament to the structural strength that the arch form provides.

The photo below shows more clearly that the arch survived the collapse but changed it shape and now the opening has a greater height. Clear Creek still flows under the arch but disappears under the new rubble pile.

The Park Service considers the formation to still be unstable and dangerous and has closed the trail to Arch Rock.

The three very short videos below by Robert Robinson were taken on April 23. The first video shows the approach on the trail that formerly went across the top of the arch. You can see fissures in the ground indicating the possibility of another collapse. The second video shows views of the collapse from the Coast Trail above the opposite side of the creek. The third video shows the still-existing arch from Coast Creek itself.

Rapid Evolution of an Arch

Arch evolution can occur over thousands of years, but La Dame Blanche (The White Lady) in France consisted of a crumbly clay-like rock and evolved from youth to maturity to collapse in the course of just a few years.

The photo below taken by Albert Zwinkels in 2009 shows a small, young opening.

The White Lady
The photo below by NABS member Guilain Debossens taken in June 2014 shows a mature span of 20 feet.

The photo below by Raphael Rodon was taken in April 2015, showing that the arch had collapsed.

The White Lady
La Dame Blanche (NABSQNO 31T-663186-4933509) was located in the vicinity of Dieulefit village in the Drôme department of France, about 100 miles south of Lyon and 120 miles north of Marseille.

Arch Hunting in Chad

By Peter Felix Schaefer

Since the first reports of the early Africa explorers of the 19th century it was known that the Sahara is really not the safest place on Earth. But it was always possible to visit at least some of the magic places in the central Sahara with limited risk. Unfortunately the situation has become a lot worse in the last couple of years. Nowadays you have not only to handle the “normal” criminals, kidnappers, smugglers and corrupt officials, but also the terrorists of Al-Qaeda and the so-called Islamic State. Chad has received the financial and military help of France to assist with such problems.

Chad Ennedi Gallery: Click on any image for slide show, ESC to return.

In 2011 and 2012 my wife and I visited Chad for three weeks each time. In 2011 the traverse of Emi Kousi attracted us (see SPAN Spring 2013). It is an extinct volcano and actually the highest elevation not only in the Tibesti Mountains but in the whole Sahara. In 2012 it was the Ennedi Plateau, a wonderland of rocks, outstanding rock art, and home of some of the very last desert crocodiles. Both trips had an expedition-like character which definitely needed good preparation and organization. This job was done perfectly by Spazi d’Avventura, an Italian family-based tour operator with decades of experience in Niger and Chad (

Both trips started in N’Djanema, Chad’s capital, which can be reached by plane via Paris with Air France, or via Addis Abbaba with Ethiopian Airlines, which is also a pretty good and reliable carrier. Spazi picked us up directly at the airport and helped with the paperwork for entering the country. We soon found out that the people on the tour all came from different European countries with different languages, but fortunately everyone was happy with English. Our Toyota Land Cruisers (two for Tibesti and three for Ennedi) were soon loaded and off we went!

In many African countries the Chinese are building new roads and this is the case in Chad too. Nevertheless we reached the end of the pavement in a few hours. From there on it was off road driving, sometimes easy, sometimes difficult. It took us three full days to reach the Ennedi and two more to get to the border of the Tibesti.

This part of the trip was a bit boring because there is not much to see in the Sahel zone most of the time. The big excitement was whenever we reached a water reservoir or a well. It was absolutely fascinating to see the nomads come and go with all their different type of cattle, goats, sheep, horses and camels. But it was also very sad to find long stretches of land with almost no vegetation, the result of grazing too many cows here. The more north and east we came, the fewer people we saw. Then all of a sudden we found ourselves in the world’s biggest desert, the Sahara.

Safe driving in the Sahara needs some precautions: at least two cars, lots of spare parts, and someone who can fix a lot more than just a flat tire, and without a garage. If you can’t take enough fuel with you in canisters, then a private gas depot somewhere is necessary. Spazi had all of this.

Ennedi TruckThe importance of safety precautions became obvious to us when we met a group of people (men, women and children) right in the middle of nowhere, hundreds of miles from the next little village and water source. The previous day their truck had suddenly stopped and they were not able to repair it, and they had no satellite phone to call for help. It was just a lucky chance that we came along. It took our car mechanic about 20 minutes to find out that the injection pump was out of order and the battery was dead. We gave these unlucky fellows as much water as possible and then had to leave.

Water is of course rare in the desert. Whenever we came close to a well, we took the opportunity to fill up our stock of water. Normally lots of nomads were already there waiting to take their turn. In situations like this our local guide Muhammad was of inestimable value. This was not only the case in the Ennedi but in particular in the Tibesti which is even more wild and untouched.

Muhammad arranged for an additional guide for the drive through a field of land mines, and also for a couple of locals with pack camels for the traverse of Emi Koussi on the first trip. Muhammad was respected a lot because of his status as a “mustati”—a man who has finished the hajj (pilgrimage) to Mecca. In spite of the knife in his sleeve and the Kalashnikov assault rifle on his back, he was a nice guy.

Balanced RockHiking the Ennedi was most often nothing less than spectacular, at least for an inveterate desert lover like me. It was not too tough because we always had a long lunch break at a place with nice shade.

Ennedi Rock ArtWe reached the campsite normally in the late afternoon, erected Spazi’s excellent desert tents, had tea or explored alcoves close by for rock art (the Ennedi has ubiquitous rock art from the last five millennia).

Dinner was great Italian cuisine. When it was not too windy we slept outside the tent and enjoyed the night sky full of stars.

With the exception of the huge Aloba Arch we never looked for arches on purpose, but ran into them more or less accidentally. In the Tibesti we found just a handful of them, but in the Ennedi on every hike we saw several really big, beautiful and most remarkable arches. Some of them have been known to us for years from the pioneering work of my friend Gunter Welz (, others were known only from aerial photos, and many were completely new.

On both trips we just had one night in a hotel, the last night. On the Tibesti trip it was a hotel a bit outside the capital city situated very nicely along a river that flows into Lake Chad. It was run by a French guy at that time. Having the first cold beer after many days and looking out onto the river was great. On the Ennedi trip we had a really good hotel in town and were invited by Spazi for dinner in a nice restaurant. The next day they brought us to the airport and waited until we all went through security. Very good and conscientious work on the part of Spazi.

As you know, there are arches spread out all over the world. But they are not equally distributed over the Earth’s surface; some places have large clusters of them. The best places for arch-hunting I have seen so far are Arches National Park in the U.S., Kukenan Tepui in Venezuela, Tassili n’Ajjer in Algeria and…you guessed it, the Ennedi Plateau in Chad!

If you are interested in more photos, please visit my website If you have questions, don’t hesitate to email me (

Organization of a tailor-made trip for arch hunters to the Ennedi is easy, but to get a good price at least five to six people are necessary. The best time of the year for a trip is from November to February, with the very best month being November. It might become one of the most memorable trips of your life!
