I would put the beach road going east from San Nicolas into the atlas - especially since Benchmark already has the east part of this road in there (26.5243,-111.4646). The beach road is not private.

Good eye, Harald... Since the base map used is the Mexican government INEGI maps, are these 'errors' also on them? I will take a look as I am one of those who bought your topo map package.

I know how much you love INEGI
that's why I checked before I posted
the names pointed out are either non existent on the INEGI maps or they are correct
H12C62 for Arroyo San Pedro
G12A68 for Cerro Ninguno

Caltopo is the quickest way to check:

I was trying to plug your product!

'Cerro Ninguno' is showing as Cerro Bola: https://caltopo.com/map.html#ll=26.51207,-111.56891&z=15...

Cerro Bola is on the other side of the road

there is a hill allright where the Cerro Ninguno marker is - only it has no name (like most mountains in Baja)

thank you for plugging my map set!

working with place names for many years I found something interesting
only if there was a need for naming a mountain, or an Arroyo, or something else - only then they would be named.
That translates to the following:
if an area has a lot of named Arroyos, mountains, Mesas - then there was significant human activity (hunting, growing, traveling)
if an area has majestic mountains and gorgeous canyons, but none of them are named - then it was an area where humans, did not hunt, travel or live.

A very large number of places have travel related names (Cuesta, Pie, Portezuelo, Potrero, Puerta, Puerto, Las Juntas)
If you want to find Camino Real without Harry Crosby, look for "La Cuesta Vieja", "Mesa el Potrero", "Arroyo el Pie de la Cuesta", "Tinaja de Los Frailes" etc
even if the INEGI maps do not show a trail where you find those names - zoom in on Google Earth and there will be a trail
I guarantee it

too bad Crosby did not have Google Earth

Way to much concentration on KM marking. Most of us ignore them and concentrate on roads and places.
Move on.
More importantly tell us about misplaced roads, road labels, and places. That is one the major issues with INEGI which is the basis of all
versions of maps regardless of who printed them or put them on a GPS map file.

Anytime!
Let's see how I got Cerro Bola from what I though (at a glance) was the Cerro Ninguno location:



I put the + right on top of the triangle for Cerro Ninguno (using the digital Atlas) and I get this GPS: 26.5131, -111.5714

If you plug that GPS into Caltopo or any digital INEGI map, you get:


The EXACT same mountain but called Cerro Bola

I think not, unless you are GPS/Map nerd (like us in this thread)!

With km. markers, you don't need GPS or even an accurate odometer.
If you're looking for a turnoff between Km. 89 and Km. 90 (on the Benchmark map), you just drive to the first posted km. sign of the two and begin looking for your road. A kilometer is only 0.62 of a mile long.
Even bad odometers will be pretty close in the 0.0 to 0.6 span.
If your road is in between the two, then only 0.3 is passed for 1/2 km. on your odometer (if your road is really faint of brush obscured).

No need for lots of math or electronics... just find that road to your secret beach off the highway, fast and easy! Viva the kilometer points on the Benchmark Atlas!

As for the rest of your comments... I think we can do it all... I know I am not bothered by helping make a better map. No need to drop one item to have the others. Let's fix all issues!

For the main highways what we now have with David's KM list is more than adequate for everyone's use. The hiccups of missing markers and errors are easy to deal with.
I was a great improvement of Atlas vs Almanac.

When you leave the highways the maps count and they should be better. That is most important.
Good paper maps and backed up with electronic maps make it best of all. I have been using my GPS maps with highway KMs noted since about 2004 or 5 and have not noted any issues I could not resolve.

The KM markers in the back country were lost years ago.
Remember the days when Bruce Barber gave directions along Morelia/Saltito, and east/west valley roads with a list like David's with KMs and turn locations. Now days maps work but KM do not work off the highways.

Agree. Nice to have a km data for intersections (or infrequent major landmarks), but anything more is clutter.

Good morning Paul,
True that kilometer markers on dirt roads seem to be less stable. They are on concrete posts rather than metal signs. They are also rare with the road south of L.A. Bay being the odd one of just a couple having them. I think the road from San Javier to Hwy. 53/ Santo Domingo, is another... I have not driven that one, so unless someone here can confirm, I just trust the Mexican government map source Benchmark uses on that.

The L.A. Bay south road was traveled by me twice in 2017 and there were no kilometer posts then. It was 'geoffff' in 2019 who recorded them. As you say, they seem to get knocked over, making them useless for navigating. But they are approx. 1 km. apart and too heavy to steal, so they lay there.

Back to the post subject. Please indicate where errors or omissions are on the 2021 Atlas so the next one will be even better. I realize Hurricane Kay (last September) really messed up roads in 2/3 of the peninsula. What were 'dirt highways' (like the road south of L.A. Bay) became rutted, washed out rough roads. Things change and Mexico's highway departments are probably underfunded to deal with repairs or regrading in a timely matter, taking years to return the road to its former glory. That said, if you think the road classifications, as shown, should be updated, let me know.

Here's an edit suggestion I got on my Facebook group page that may be of interest to Nomads:
Show the original Coco's Corner (1987-2021) as a historic point-of-interest.

The new Coco's Corner (April 2021+, at Las Arrastras) continues to be open for business following Coco's death on August 30, 2021.

Thanks Paul, Geoff, and others, for you valuable input!

I find it useful to see abandoned places on maps. I do not want to forget such places so I like the reminder. That is also be true for some back country roads and mines as well.
