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).

An Accessible Arch Cluster in Grand Canyon

Rob Jones (The Wilderness Vagabond) reports a cluster of four natural bridges made of Kaibab Limestone only about a half mile from the trailhead at Hermits Rest at the end of the West Rim Road in Grand Canyon.

Called the Four Sisters, the arches were well known to the “hermit” himself, Louis Boucher, who included them on tours when he took tourists into the Canyon in the early 1900s. Originally called the Three Sisters, they became nearly forgotten. Rob learned of them from a Park Ranger who did not know their exact location but steered him in the right general direction and he was able to find them.

Below are two of Rob’s photos, followed by his video that shows all four of the arches.

Four SistersFour Sisters

Directions: Walk one quarter mile down the Hermit Trail, starting measurement at the trailhead sign. Watch for the low canyon off to your left, going down. As the trail gets to an easy access, drop into this low canyon and walk up canyon for 0.4 miles, taking the right canyon at the first branch, and the left canyon at the second branch. The natural bridges span the low drainage at NABSQNO 12S 391078 3990950.

A more direct way back to the trail can be hiked from the first fork you took going up canyon. Just hike north up the side of the canyon and back to the main trail (see map below). Or you can return the way you came. The whole loop is about a mile.

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:

Doc Martin’s Arches

By Ray Millar

The British TV series Doc Martin (a “dramedy” shown in the U.S. on PBS) takes place in the fictional seaside village of Portwenn and is filmed on location in the small quaint picturesque village of Port Isaac on the north coast of Cornwall. There are two small quaint picturesque arches nearby (which as far as I know have not been seen in the ongoing TV show).

Ladies Window

Ladies Window

I have seen this arch called by its singular name Lady’s Window on the Internet but it is marked on the Ordnance Survey map as plural so I will use the plural form. It is about 7 miles from Port Isaac roughly midway between Boscastle and Tintagel, legendary site of King Arthur’s Camelot. It is near the small village of Trevalga just off the coastal path to the west. The opening is barely visible from the path but there is a wooden post marking a grid point by the arch. The photo was taken from a nice bench where you can sit and look at the views. It is at 30U-378275-5616085 and has a span of 6 feet and a height of 9 feet.

St. Nectan’s Kieve

St. Nectan's Kieve

This waterfall natural bridge is close to the village of Trethevey and there is a parking area for it off the road from Boscastle to Tintagel. When I was there about 10 years ago I had to walk a two track road that led to a small cafe and tearoom. Here steps lead down to a waterfall about 60 feet high where the River Trevillet has punched a hole through the kieve (basin). A fee is charged. There is now a one-mile trail that goes alongside the river before climbing up to the tearoom.

The sixth century Saint Nectan is believed to have had a hermitage above the waterfall and is said to have rung a silver bell to warn shipping about the rocks at the mouth of the valley. It is said to be a mystical place where fairies, piskies (Cornish pixies) and spirits play. Visitors often leave ribbons, crystals and bells on the rocks and foliage. There are a number of small piles of flat stones by the bridge known as fairy stacks.

It is at 30U-378734-5613967. It probably has a span of about 8 feet and a height of about 9 feet (maybe less).

Port Isaac

A couple of photos of the village of Port Isaac are below. Doc Martin’s house is the smaller one in the center of the first photo.

Merwin Canyon Arch, Utah

By Peter Felix Schaefer

Merwin Canyon Arch is on BLM land in Kane County, Utah, east of Zion National Park. Merwin Canyon is a side canyon of Bay Bill Canyon which itself is a side canyon of Parunuweap Canyon, the canyon of the east fork of the Virgin River. While the lower part of Merwin Canyon is just a sandy wash, 0.6 miles upcanyon it becomes a beautiful and easy to explore non-technical slot canyon. The arch is right at the entrance of the slot.

The opening has a width of approximately 40 feet and a height of approximately 25 feet. To take a better photo than mine, bring a tripod and a wide angle lens; take several photos with different exposures and then at home you can create an HDR photo on your computer.

Taking a GPS reading at the arch was not possible for me but it should be close to 12S 346250 4114530.

Directions: Less than a mile south of Mt. Carmel Junction turn west on a dirt road and drive on it about one mile to a fence with a cattle guard. Park there and walk down Parunuweap Canyon on a public road through private land for about 5 miles to the confluence with Bay Bill Canyon. If you have a 4 x 4 you can drive here if you don’t mind crossing the ankle deep river many times. Hike up the sandy wash of Bay Bill Canyon for 1 mile. Then turn left and walk up colorful Merwin Canyon for 0.6 miles to the arch and the slot.

If you go back and hike up Bay Bill Canyon a bit further, there is another very long slot to explore. Some photos of both slot canyons can be found here:

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:

Money: Etretat France
Paper bank notes have also been produced. Below is Pigeon Rock in Lebanon.

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 photo below taken after the collapse shows that Miller Point is now an isolated butte no longer accessible by the trail that used to go across the top of the arch.

The photo below shows the large pile of rubble after 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 White Lady
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.
