1948 Baja Geology Map

Has some interesting trail, town data.



A couple close ups:


Charlie's Water = Agua de Chale (Nuevo Mazatlan)



Leon Grande is of interest. Rather than take the gold ore east to L.A. Bay, the trail goes north to Calamajué, and off the map: the Pioneer Mine, Molino de San Francisquito (de Lacy), and the shipping port at Punta Final (Puerto de San Francisquito).


EDIT:

The full map in sections:

some years ago i was loaned and promptly lost a book that was half geologic guide to baja half novel. i would love to learn more about baja geology.
a guide structured according to what a motorist would see along
the highway would be cool.

I love old maps. In my youth I would spend hours at the Flagstaff library pouring over old maps looking for long abandoned mine sites. I would painstakingly recreate them in pencil and then go off in search.

Thanks for posting this one David.

A good geology book is:

The Baja Highway by John Minch and Thomas Leslie.

For those interested in such things here is a link to a 1921 geological survey of Baja California as far south as Todo Santos. There are pictures, maps and drawings.

We have discussed Leon Grande and Agua Leon at some length here on Nomad. Search 'Leon' to find the posts.
These were major sites in the 1920s but vanished from most maps in the later decades.
I knew a prospector who said he worked the area northwest of Punta Prieta...

David, where can I find the geo map you posted at the top of this thread? A higher res version would be great.

Great thread! Thanks for all the great maps DK

The trail that passed Agua Leon, a water hole, on the way south to Punta Prieta was mentioned by travelers in the 1920's. This trail appears to be pretty far west of present day Hwy. 1, which of course then did not exist.

The geological article linked above has a good description at the very end of why sea shells are found at elevations far above sea level in Baja due to the land being raised up.

An internet friend, who is a geologist, sent me those... The whole peninsula map that the smaller area ones came from was too big to email me. So, I have to request areas of Baja for close-up looks. He is a contestant in the NORRA Mexican 1000 this week, so it will need to wait.

De nada Ric... I hope we can go out checking that place. Yes, the route was well described in Howard Hale's book! Long Walk to Mulege.

I bet that pssid off the librarians. :lol:


Actually the guy at the desk came to know me and was very helpful.

Nice job! Thanks Lance.

Nope.
Here is a clue:

DK thought the spring of the lion was near
it was only the Deer
The map of the Aleman
was more spot on
From the mouth of the lion
look to the south
a straight road to nowhere
that Hale did mouth
To nowhere no more; to the Parador
southwest of the mouth, low hills and a spring
The water that the Lion did bring

There once was a man named Stroppe
Who built a Bronco that was non-stop
As he said with a grin, while sipping his gin,
If PJ is my driver, at the podium we will stand on top!
