Marron Valley, Most Open Part Of California Border

Between Tijuana and Tecate there are still about seven miles of wide-open border. This post shows how it looks and issues are discussed that may explain why it has been left open. Some of it is rocky, mountain ridges, but still there are a few miles, where a person can walk across on relatively flat ground with no barrier at all to stop him.

Though it still needs some work, the state of the Border Fence is really pretty good along the rest of the 160-mile California border, tremendously better than it was in 2018, before the new construction started.

However, Marron Valley is just one place that was skipped for some reason. Maybe it is for a good reason? It is probably because this section presents a more difficult engineering problem than most other sections. So, it was not rolled out like other sections of fence on the border with a more standard, less expensive design.

You might compare this section with the small section that runs into the Pacific Ocean near San Diego. That section has not been replaced either. It would take a special design and a crew with special skills to construct a bollard fence that extends into the surf. So, that part has apparently also been left for a future project.

This map shows the layout of the area. It is about 11.5 miles from Tijuana (or Otay Mesa on the US side) to Tecate. There is about four miles of pre-existing fence, built around 2008-2010 on Otay Mountain. 1.5 miles of new double fence is being constructed on the west side to better secure the Otay Mountain area. However, there are about seven miles of border that has no barrier whatsoever. You can click on these images to obtain a larger view.

This map shows a closer view of the current gap and is at an angle compared to the previous map to better display the terrain. It shows where the fence stops on the slopes of Otay Mountain. The area of completely open border extends from there about seven miles across Marron Valley and across the slopes of Tecate Peak to the outskirts of Tecate.

This is a close up panoramic image of one part of Marron Valley at the end of Marron Valley Road in . The border would be about 100 yeards on the other side of the river in this area. You can see that there is no barrier on the border at all and a dirt road that crosses the border.

Here is a broader view of the same part of Marron Valley above.

I was told I could see into Maroon Valley from the top of Tecate Peak. The road can be pretty rough, but you can drive all the way to the top with an all-wheel-drive vehicle if the road has been graded recently. The distance is about four miles to the top.

This is an overlook of Marron Valley on a hazy day. You can click on this photo and expand it for a better view. You just make out the Tijuana River bed as a meandering dark line of trees/brush at the bottom of the valley. ( I may go back on a more clear day for better photos.)

Next is an Image of the terrain to the north of the border and Marron Valley. If you look to the very left side, you can see the Tijuana River as a dark splotch at the bottom of the valley.

Certainly there are many paths illegal crossers can take to hike across the border here to a pickup location on Highway 94. You can click on this panoramic image and obtain a larger, high-resolution view.

I did not approach the border from the Mexican side, either, as I sometimes do, because only dirt roads lead down to the border in that isolated area and there are serious drug operations taking place there. A young Mexican citizen, working for the US Embassy as an agent for the U.S. Department of Agriculture was killed in the area just across the border while collecting insects in October, 2020. The Narcos apparently thought he was spying on them. His body was riddled with nine bullets. So, I decided not to try to approach the border on the Mexican side for a better view!

The image below shows the fence as it ends on the slope of Tecate Peak just west of the town of Tecate. The town of Tecate has a new 30-foot bollard fence, but this smaller section going up the slopes of Tecate Peak is an older, 15-foot fence, probably built around 2008-2010. From where this fence ends, there is no border barrier for about seven miles until the fences starts up again on the east side of Otay Mountain.

Finally, here is a photo of Tecate and the border wall from Tecate Peak. The dark line dividing the U.S. and Mexico is a 30-foot bollard fence. I it actually about 26 feet high, but construted of 30-foot bollards, with a four-foot high anti-climb plate on top. The actual height depends on how deep the bollards are set in the ground.

I have not talked to the Public Affairs Officer for the San Diego Sector about why there is no fence, at all, in this area. I speculate that the reason they have not built a new fence here is probably due to the expense of building in this rugged, isolated area and also that it would be a significant engineering challenge to build a fence here. The likely reason is that the Tijuana river meanders back and forth across the border and also the run-off from mountain slopes drain into the Tijuana River. The river is probably dry or nearly dry most of the time, but when it rains there will be huge flash floods that could wash a fence away, even when it is set in concrete several feet deep. They don’t build in river beds. They could build a little north of the river, but there may be a land ownership issue with that.

It is cheaper and easier to build in other places and so this place was probably at the bottom of the list. They were trying to build as many miles of fence as possible with the funding that they had before Trump might have to leave office. Maybe they will be able to construct a barrier here in future years?

Tecate Border Fence Complete – October 2020


Four miles of 30-foot steel bollard fence have been finished in Tecate, California. Previously there was mostly landing mat fence here 8-10 feet high and a couple of small sections of low bollard fence that was built probably around 2008. Landing matt fence was originally intended only to stop vehicles, not to stop persons crossing on foot.

View towards the east.

The fence runs towards Mt Celli in the east an older, it is joined up with and older, pre-Trump, bollard fence which already existed on the hill.

This vehicle belongs to Marines assisting the Border Patrol directly on the Border. My understanding is that they watch for illegal crossers and call the Border to apprehend them. They use the van to transport detainees. The back area of the van has been modified to transport prisoners. I did not take their photos, because they did not want to be photographed.

Armed U.S Marines guarding the border.

In past administrations they would talk about sending troops to the border, but they would not be armed and not directly on the border. These Marines are armed with loaded weapons and they are directly on the border. There are probably hundreds of them deployed in this way along the entire border.

The next photo shows the transition from the “Trump Wall” to the “Bush Fence”. The pre-existing bollard fence on the right was most likely built in the last couple of years of the Bush administration or the very early years of the Obama administration, before Obama cut it off. On the left is the “Trump Wall”. In this area, the older Bush bollard fence is about 15 feet tall and the new Trump fence is about 26 feet tall. It depends on how deep the foundation is and they may have reason to plant the bollards deeper here, such as to discourage shallow tunnels under the fence.

Transition from Trump Wall (left) to Bush Fence (right).

The Border Patrol has been calling this a “fence” for about 15 years or longer. There were a couple hundred miles of this bollard fence on the border, before Trump. They have long experience with it and this is the design they wanted to continue with the new construction. It is much to Trump’s credit that he gave them what they wanted. It is not the Border Patrol’s fault that the earlier fence was often dilapidated junk. It was the fault of past administrations, who did not support border security adequately.

This photo shows a section of the older Obama fence in the foreground and the new Trump fence in the back ground. Some of it was there before Obama’s term in office, but I call it the Obama fence, because he was legally obligated to build a secure border fence by the Secure Fence Act of 2006. Obama did not attempt to do it so he owns the previous fence.

Even the concertina wire was added during the Trump administration. Earlier, there was only the vehicle barrier in this area made out of sections of pipes wielded together. A person could just walk across in this area to the east of Mount Celli. In the middle of Tecate, it was the landing matt fence, which us only slightly better.

This next image is from the Mexican side, made in 2016, before the new fence was built. It shows this section of the border just east of Mt. Celli before the new fence was built. There was a couple hundred yards of old 15-foot bollard fence going across Mt. Celli. Down below in the dry wash there was nothing except the rail fence with not even any concertina wire. Why would anyone build a bollard fence on the hill when it was much easier to walk across in the dry wash below? There are many more areas like this in Campo to the east.

This image shows one of the crews a little further to the east of Tecate working to finish the Campo section of the border fence. There are reportedly several contractors working on the Campo section in order to have it finished by the end of this year.

On the west side of Tecate the fence extends partway up the side of Tecate Peak. The last few hundred yards is a Bush-era, 15-foot-high, bollard fence. Try clicking on the photo and expanding it to find the vehicle of the Border Patrolmen hiding behind a large boulder to the right of the end of the fence, waiting for illegals to cross.

There are no plans as far as I am aware to extend the fence further across Tecate Peak. On the other side, of the Tecate Peak, between it and Otay Mountain, are about 6 miles that are completely open, much of it along the Tijuana river. There is no border barrier at all there. It is going to be the most open part of the California border, after this new fence is totally completed. I am not sure why they are not building there. It could be, because the Tijuana river criss-rosses the border several times in that area. It may be an engineering challenge to build a fence in that area that would withstand flash floods in the riverbed, which are not uncommon.

Next is a video that I made when the work on the new border fence started in this area in the late summer of 2019.

This video by a Mexican reporter for “California Medios” is from 2016. I reused it and subtitled it in English. It shows how easy it was to cross in the middle of Tijuana and the conditions in this area are discussed, such as the kidnapping and extortion of illegal crossers by criminals. It also indicates how the local police feel about it. The reporter says that it takes less than 5 minutes, but in this case the actual crossing of the old border fence took only about 20 seconds for the three of them to cross, one of them very much overweight.

Jacumba Border Fence Update (Skull Valley) for September, 2020

In early September, a new fence was being built in the Jacumba Wilderness. It’s called the Jacumba Wilderness, because it is an isolated, often extremely rocky area which few people visit, except for hikers and off-roaders. The Jacumba Wilderness is about 11 miles wide. There has been no border barrier at all other than the ruggedness of the natural terrain.

Location of Skull Valley

There are a couple of valleys in the Wilderness, where they are building 30-foot bollard fence. This photo below is of the Skull Valley, named apparently for those who unsuccessfully try to cross in this area. The contractor has built a paved road into the area.

Below is video from last year of the Jacumba area. A crew is also staging near the town of Jacumba and will be expanding the existing 15-foot high border fence in that area. They are preparing to extend the fence up slopes in that area and probably will be replacing 0.7 miles of old landing mat fence near the small town of Jacumba.

Earlier report on the Jacumba area from 2019

Border Fence Status in Jacumba, Ca

Report on the status of the existing border fence in Jacumba, Ca for November, 2019. Most of the the six miles of existing fence is already bollard fence that was installed in 2008 during the Bush presidency. A small part is landing mat fence that was constructed about 25 years ago, during the Clinton term. It is not known, whether there are any plans to upgrade or add to this existing fence at this time.
