Thank you geomike for the link to the map.
I spent several pleasant hours today scanning that map and trying to make out how it related to what I had seen all these years. It explains why there
is water in the canyon by the Santa Maria mission and why Morro Santo Domingo looks so incongruous with the rest of the area.
The blue and green areas would be interesting to explore for minerals, I would think. Is there a corresponding map for Baja Sur? I'm wondering if
there's the same green area near Santa Rosalia as the one near El Arco.

I have a hard-copy of the same Geo-map as David shows here, but I don't believe there was ever a southern Baja quad made -------just don't think it
was ever completed by the same team, but I could be mistaken on that, SkipJack.

You're right, Barry. He and his students didn't map the southern regions.
BTW, the author of this wonderful work passed away just a very few months ago:

David, check with Georock... but, I have not seen her around here lately.

Hey David, here is a fossilized clam taken from the Gigantes behind me. As far as age, it had to precede the upheaval of the mountain.

Oh I did get it, he meant to insult Christians who take the Bible date as Gospel, ... and why not tell him to stay 'on topic', it is my thread, after

She is one of my Facebook friends, and she is out there, just not here. Many good people just get tired of the confrontation or whatever (as in this
thread, now), and don't come here any more... sad.
I post as much for the lurkers who love Baja and want to know or see more (but won't join Nomad) as I do for my friends here, such as you Bob.

I told you where to generally find Ordovician fossils and purported Precambrian sed rocks. If Precambrian sed rocks in north Baja don't get your
juices flowing, then you are hopeless! Precambrian! Crickey! (Isn't that more exciting than a Cretaceous ammonite or a Miocene oyster !?!?!?!?)
People that take bible dates as truth! Dios mio!

I get nervous when I read Picacho del Diablo has sea bed fossils near the summit of 10,000+ feet altitude. I also get nervous when I read and hear of
earthquakes occurring on the Vizcaino peninsula and then not finding any faults at near anywhere near the area with geodetic survey maps. I think this
peninsula has some whoppers in store for those who live here and think they have it all figured out.

Technically, the peninsula is only around 7 million yrs old (it was still part of the mainland)---the rocks that compromise the pensinsula are 65 my+
though. Evidently, some of the desert paving out there is river rock deposited by rivers that flowed from present day Sonora out to the
Pacific...pretty cool stuff!

Found these mid-peninsula...Taco de Baja thought they looked like brachiopods, some of which go way back into to Ordovician (450 mya)...these rocks
look quite old and "cooked", possibly by a nearby emergent granitic pluton.

Fossils at the summit of Diablo? Really? It's all granite up there; someone's pulling your leg with that story. However those mountains were pushed
up there by movement along faults, and yes it’s been fairly quite over the last 100 years or so, aside from that “little” Easter shaker in 2010 in the
general vicinity…  . There will no doubt be more whoppers for in Baja in the
future.
Now if you want scary elevated fossils, consider there ARE seabed fossils on Mt Everest (29,035 feet). Pushed up there by plate tectonics and
earthquakes (not a "flood").

Brooks, that is what I wonder about a site like Las Pintas... 600' plus above today's sea level and over 15 miles from today's coast. On the opposite
side of Baja, about 400' ASL and 5 miles from the coast...
The question is was the sea level hundreds of feet higher or did Baja raise up from the ocean that existed when those oysters and lobsters were alive?
Now over in West Texas and New Mexico, we have the Guadalupe Mountains and Carlsbad Caverns that we are told was a ancient reef under an ancient sea.
Loving the historic geology!

The land rose up.
Just like along the San Diego, Orange and Los Angeles County coast lines where we can still see (in spite of the development) some of the wave cut
terraces on the coastal mountains. The San Joaquin Hills in OC are over 1,000 feet high and rose up in a little over 1.2 million years. At the top of
the San Joaquin Hills there are 1.2 million year old marine terraces cut into the hills with sediment that are around 10 million years old.
The Palos Verdes hills in LA have well developed, and well-studied terrace deposits.
San Diego has a bunch too. The nice flat bench in Camp Pendleton, near the check point, is a wave cut terrace that’s around 120,000 years old.
The flat areas around San Quintin and just before El Rosario, same thing....
There are also marine terraces off the coast that are currently below sea level that record sea level changes over the last 18,000 years as sea levels
rose 400 feet in response to melting glaciers.

Almost all of Baja has been uplifted Miocene to today. Most of coastal Baja has Pleistocene terraces, punta Banda has really nice collection of wave
cut terraces.
Several terraces are submerged offshore. Anthropogenic sea level rise will submerge another terrace offshore, a terrace with lots of human detritus
that may be of some interest to future fossil hunters, perhaps providing environmental lesson for future earthlings

The greenland and antarctica ice sheets account for 99% of all freshwater ice on land. If they melted sea level would rise about 210 feet. So any
fossils above that elevation could not have possibly been produced without rising land masses.

Nothing is guaranteed Goat. Animals die and we get to find their fossil remains. Change is part of the cycle of life.
BTW, what lessons did we not learn from the melting glaciers that caused sea levels to rise 400 feet between 18,000 and 8,000 years ago?
Whose fault was it for this "devastating" period of "climate change"? Just think of all the poor animals (and people too) who were displaced by this
massive flooding and inundation.....It was a heck of a lot faster than anything we are experiencing now.
