Ejection Seat Ridge Plus - 2/8/18

From Ejection Seat Ridge to Spring Mountains

Diversion Slot #1

Red Rock Outcropping Window

Starting up Diversion Slot #1

 Ah, the Bitter Ridge Limestone Member of the Horse Spring Formation (aka Rainbow Ridge). Made of limestones that were *formed as calcium carbonate precipitated in a freshwater lake that filled a basin formed during regional extension in Miocene time. Add to that the Red Aztec Sandstone in the same area. And, the black basaltic rocks scattered among the red outcrops. *In this area of intersection of the major faults (Las Vegas Valley shear zone and the left-lateral Lake Mead fault system), the rocks have been sliced, tilted, thrust over each other, and folded.

Hiking up Slot #1

 It is in this area, between mile marker 13 and 15 of the Northshore Road that seven hikers (on a morning with cross town traffic jams up the wazoo) set off to enjoy the geological colors and shapes made in the Miocene time.

Textures of Slot #1

 We parked at a turnout on the south side of Northshore Road at mile marker 14.5. The embankment down to a large wash that runs parallel to the road is steep and deep but there is a trail that takes hikers down to the bottom.

Arriving at End of Diversion Slot #1

Heading out of Slot #1

 This particular hike was built on the fact that an air force jet crashed in a wash in this area around fifty years ago. The pilot ejected and survived but the ejection seat remained where it landed on this ridge across from Rainbow Ridge above the redstone. Even though the main point of interest is the seat and the plane crash, this area is fraught with color and maze-like canyons. Today, our hike that was originally created as a four mile hike became a six miler with added diversion slots that delve into the side of Rainbow Ridge.

Back into Road Wash

 In the deep Road Wash, we turned to the left and began following what we assumed were horse tracks in the sand. About a third of a mile up the wash, we turned to the left to climb out and cross the road.

Climbing out of Road Wash

 Across the road and to the left a tad, we dropped down into the wash on the other side. BTW, this trail down has been washed out recently and care must be taken. However, there is a more gentle route on down the road.

View East from Ridge

Narrow Route up to Ridge on East End

 We turned right and began hiking up the wash that soon became a slot. This would be known as Diversion Slot #1. At the end of this wash, we saw that this was a favorite place for the bighorns to hang out; probably in bad weather. We noticed that we were directly under a landmark pointy spire above. Back at the road, we crossed back over and dropped again into the Road Wash, turned left and continued following the horse tracks. Further up, we forked to the right and climbed up. This put us on top of the desert terrain. We saw the "UFO Rock" at the far end of the ridge to our right and began heading toward it in pretty much a straight line.

View from Route Up

 The straight trajectory of our route required us to cross a couple of arroyos on the way but today's group was strong and it was no problem.

Rainbow Ridge from top end of Ejection Seat Ridge

 When we reached the UFO Rock, we found a trail under it then circled around the rock to put us at the end of the ridge.

The Group at the Ejection Seat

 Now, we were faced with the narrow climb up to the top of Ejection Seat Ridge. This climb can be more daunting to less experienced hikers but we pushed each other up easily. The views from the top end of the ridge are amazing in all directions. In addition to the many colors of rock around, we could see Lake Mead and Callville Bay, named after *Anson Call. Call was a man sent by Brigham Young to find a good spot on the Colorado River for a freight port. The settlement was named Callville and was established in 1864. However, only 5 years later the port was abandoned due to the completion of the railroad through Utah. The ruins of the settlement can be found under hundreds of feet of the water of Lake Mead.

A Few of Many Airplane Crash Parts

 The hike continued down the ridge. We took our photo at the ejection seat then crossed down to the Crash Wash. Slowly, we made our way down the wash taking photos of the various airplane parts that were still there.

Connecting with the Trail at the Bottom of the Crash Wash

 Care must be taken in the sometimes steep and slippery wash. You would not want to get cut by the exposed aluminum edges.

Gentle Descent on Trailing Ridge

 At the bottom of the wash, we turned left onto a trail and followed this over at the foot of the ridge. Wondering where it continued led us to a cliff! We came back to a trailing ridge and began a gentle descent. The ridge doglegged to the left. When we were parallel to a large red Aztec Sandstone outcropping, we turned to the right and followed another gentle ridge down to it. Here, we climbed on the rock and took our break. There were many points of interest in the rock here, including arches, fossils, a sun etching and a rat's nest.

Arriving at the Red Rock Outcropping

 After we had a very relaxed break, we found a small wash to follow on the road side of the outcropping and started a small scramble down.

Various Point of Interest at Outcropping

 This small wash led to a midway wash and on down to the main wash that flowed from Rainbow Ridge. We turned to the right and followed the main wash through a very colorful narrow section.

Humpty Dumpty Arch

Scramble down to Main Wash

 We passed the entrance to the Road Wash where we would return after our Diversion Slots #2 and #3 and hiked through a rusted culvert to the other side of Northshore Road. Today, Slot #2 was a new wash we wanted to explore. We turned to the left and followed this wash until we found a wash turning to the right that had a high cliff on its left side. We hiked up this wash taking a fork to the right and ended up in an area where there was a lot of brush. We decided that this area must get a lot of water flow on rainy days. There is also a hikable steep hill up to the right that may be used for a future route.

Main Wash to Rainbow Ridge

 It was a warm day so we didn't want to take too much time on our explorations and we returned to the culvert junction.

Colorful Slot - Anhydrous Iron Oxide Minerals (Red)

 We decided to take a reconnaissance "look see" at the difficult dry fall that ends a descent from Rainbow Ridge. So, we turned to the left and started up Diversion Slot #3.

Small Scramble

Diversion Slot #2

 These slots are truly beautiful and each are very different. *Their vivid colors are a result of a combination of normal weathering processes and a generally oxidizing environment. Yellow colors are produced by hydrous iron oxide minerals, red colors by anhydrous iron oxide minerals (hydrous minerals contain water, anhydrous minerals do not), and black by manganese oxide minerals. Combinations of these minerals produce the various intermediate hues. Like cake coloring, a little goes a long way. A mere trace of a mineral can give strong color to a formation. In sandstones, the color is usually not in the sand grains themselves, but in the cement (silica, iron oxides, or calcium carbonate) between the grains.

Brush in Wash made of Hydrous Iron Oxide Minerals (Yellow)

 Diversion Slot #3 ended at the ten foot dry fall and we discussed how it was best to conquer the drop. A strap or rope is probably the best choice.

Climbing into Diversion Slot #3

 Decisions were made to be prepared with a strap on our next endeavor across Rainbow Ridge. The canyon above this dry fall is just too good to miss just because a simple ten footer lies at the end.

Dry Fall in Slot #3

Exiting Diversion Slot #3

 We returned down to the culvert and crossed back to the other side of the road. The main wash took us back to the entrance to the Road Wash and we turned to the left. A beautiful hike up the wash following those horse tracks took us back to the embankment below the cars. From there, we climbed the hill with our last bit of energy. It was a wonderful morning. Fun to explore. Relaxed in pace. Somewhat intimate.

Virlis-Fisher & Bridge Spring Arches - 2/3/18

Virlis-Fisher Arch

Bridge Spring

Miocene Andesite to Left of Saddle #2

Dirt Bikers across Highway 165

Virlis-Fisher Arch and the natural bridge of Bridge Spring are located within the Eldorado Mountains approximately 2 miles from the small town of Nelson, Nevada. The trailhead is a small pullout with adjoining dirt road situated on the north side of State Route 165. It is located on a crest previous to where the highway dives down into the little town. Drive south on 95 around 10 miles from the Cascata Golf Course. Turn left onto Highway 165 and drive another approximate 10 miles to the trailhead on the left. This area has become popular in the past decade for dirt bike racing and camping off the grid.

Lush Desert Foliage

Some time in the 18th century, gold was discovered in this area. Hostile Mohave Indians prevented the gold from being mined until beginning around 1857. The original mining town of Eldorado is now under Lake Mohave along the Colorado River but the mining continues to this day producing millions of dollars worth of gold, silver, copper, lead, and zinc.

Dropping to Bridge Spring Wash

First Gathering

"The small quarry cut into the side of the hill to the left exposes the tuff of Bridge Spring, a regionally extensive ash-flow sheet that erupted from a caldera in the Eldorado Mountains about 15.2 million years ago. The hills extending away from the road to the left are thought to be composed of a thick section of this tuff that was deposited against the wall of the caldera. The caldera wall, and the tuff, has been tilted 90 degrees onto its side. The tuff exposures are cut by a left-lateral strike-slip fault that represents an adjustment or tear fault in the upper plate of a major detachment sheet This unit is named after Bridge Spring, located about 2 miles north of Nelson and about 1 mile east or S.R. 165."

Climbing up to find Rabbit Hole #1

This excerpt describes what you see as you approach the trailhead. Much of the rock here is Miocene andesite as influenced by the lava flows from millions of years ago.

Exit Cave from Rabbit Hole #1

Thus, the name of the Bridge Spring natural bridge and ridge of mountains in the Eldorado Mountains along Techatticup Wash. Twenty-three hikers arrived at the trailhead for the club's first hike here in four years.

Exploring Rabbit Hole #1

Steep Drop back to Bridge Spring Wash

In the past, we have done this hike in a clockwise direction while taking in the Virlis-Fisher Arch first by way of some interesting washes. However, today, we began our hike in a counterclockwise direction and we started out the trail at the end of the small dirt road to the east. This trail took us up and over a small ridge then winds down into the Bridge Spring wash that flows eastward. Before we got too far in the wash, we climbed up northward and searched for a known rabbit hole. It's been a while (like I said) so we missed the entrance. Nevertheless, we circled around at the top of the hill among the rock and found the very interesting cave in which the rabbit hole exits. We played around here for a few minutes then headed back down to the wash below.

Bridge Spring Wash Scramble

There was another small group of hikers in the wash as well. Very unusual! But, they were just finishing up at the natural bridge when we scrambled down.

Almost down to Bridge

Some of us climbed up to the top of the bridge. The rest of us stayed down to take photos. It was a perfect day with a bit of wind whenever we were on top of something.

Bridge Spring Natural Bridge

Climbing steeply up from Bridge

As all of us finished our perusal past the bridge, we headed up the hill to the left. Here, you can see that hikers have made this climb with somewhat of a trail. A short break midway put us all together again then we finished the climb. At the top, the trail continued over a small saddle and around a hill. Another small saddle then we were at the top of the Rabbit Hole #2 small canyon. There is a trail here, too. Then at the end of the canyon, we all dropped down through a large hole made by several large boulders and came out at the bottom of a very large valley. Perhaps a fault zone.

Following Trail around to Descent

Each time we had an obstacle that required special care or single file, we were happy to stop the rapid speed of the hike and wait for everyone.

Descent Canyon

At this point, we could almost make out Virlis-Fisher Arch in the wall of rock cliffs high across the valley. It was difficult to tell but the telltale sunlight told the tale. (Hmm.)

Rabbit Hole #2

First View of Virlis-Fisher Arch

Our target now was the saddle up on the ridge to the northeast. Although there was a game trail for much of the way, it felt more like a bushwhack straight over (passing a lone red barrel cactus) and up to the saddle. Some of this had steep slippery footing but this was only a hint of what was coming later. We all ended up on the saddle with a simply amazing view of the Colorado River, Lake Mohave and the Lake Mead NRA. Worth the climb! We stopped here for a few photos and held onto our hats. This saddle/view was not included in our previous hikes here and the writer was very impressed! This is a must do!

Climbing up to Saddle #1

Next, we were told that the upcoming climb up to Virlis-Fisher Arch was optional if some of the hikers chose to stay grounded. We divided into two groups.

Saddle #1

One group headed down into the valley again for their break to watch the other group traverse around to the base of the arch where a very steep climb ensued to the east of the arch.

Colorado River from Saddle #1

Traversing over to Steep climb to Arch

The traverse trail is nothing better than a game trail and it is very difficult to tell exactly where the arch is from this angle. A good landmark is the rock formation seen through the arch in the first photo. This rock is not far to the west (left) of the arch. Some hikers climbed up a wash and others climbed up the steep loose rock covered slab. Any way you do it, it's fun! So, we took our photos and ate a snack with some conversation. Afterwards, we went through the arch and descended the first crack ... most of us on 5 legs. At the bottom of the crack, we crossed over to the first ramp ridge to the west and descended to a meeting point made of large boulders near the bottom of the valley.

Arriving at Virlis-Fisher Arch

The leader came barreling down the ramp and took off down to the valley wash. We fell in line. Soon, we were able to look back and get a better view of the arch in the distance from the west side.

Taking a Break next to the Arch

The easy hike down the fine gravel didn't last long before we turned into a wash to the left onto a trail. We began to climb again.

Arch descent Chute

Arch and Descent Chute from Ramp

The trail was pretty good but a small group of our hikers decided to drop back down into the wash below and "do some bouldering." The remaining group stayed on the trail. We didn't see the bouldering group until after we had reached Saddle #2. Our trail was difficult to follow at one point but we continued our upward momentum doing some bouldering of our own and catching the trail again at a later time. We waited at the saddle for a few minutes and still didn't see the other group so we began to amble back toward the trailhead that we could see as the crow flies. We used a use trail for most of the way but it was very vague.

Valley Wash

Many of us dragged our feet since we didn't want the group that was behind to lose us. Mainly, we were not positive that that group would arrive at the saddle.

Connecting with Trail to Saddle #2

Finally, we saw them cresting over a hill above! All was well! Our large group of twenty-three were now strung all the way across the desert from the saddle to the cars!

Arriving at Saddle #2

Starting Bushwhack/Trail hike over to Trailhead

Each time we peaked out on a ridge, we would look back and make sure that all was still well. It was and they were catching up just fine. We connected with the initial Bridge Spring Trail and climbed up over the last ridge and down to the cars noticing a new (2003) survey marker next to the short dirt road. The dirt bikers were gone and so was the other group of hikers. A wonderful hike full of discovery out in the middle of the beautiful desert.
