What's the deal with these mosaics, question for geologists

Like, The Day Of The Volcan, this happened (& why no vegetation?).

BajaBlanca - 9-23-2011 at 12:19 PM

no answers ? I always thought it was just the way the lava had flowed but actually, I now see that the vegetation seems to have sprouted up between lava rocks ... hmmm

I'll bet DK has that info buried in 1 of his Baja Collection
books, in all
sincerity I believe he most Baja books in print and
out. On a lark, you might look up a Geology Prof
at 1 of the local Universities send that pic.
I first saw those on a Mtn just so. of Playa Requeson
end of Conception Bay

Have seen similar to this in the Rocky Mountain Nat'l Park above the tree line.........

slope is steep, talus slope. brush is growing where soil is near surface. bare areas are mostly rocks, so no soil near surface and no brush growing.

the talus slope is mobile, that is, the rocks and colluvium are over time episodically traveling down slope, so bare areas may also be areas that have had more recent transport.

That's a dry, steep ridge!:)

I think there is more than one Nomad geologist, but I will ask the one I know to come here and take a look :light:

WORD OF THE DAY!:light:

good job goat!

Who has the photo of this one?

Mulegena - 9-23-2011 at 04:16 PM

There's a mountain adjacent to the highway south of Playa Requeson, I believe, that clearly looks like a whale. It appears to be outlined in white rock.

I've no idea what causes this phenomenon and have always marveled.

Thanks, Goat, for the post.

the outlined rock forms were the art project of this artist that did it a few years ago using cal.

Great discussion, thanks

These are nice photos, DK! How long ago were they taken? I think the outlines are less distinct now, and without maintenance it may fade away some day.

I know for certain that it was conceived and carried out by an artist who is a native of Baja Sur. A friend of mine met him some years back. I've always wondered how much of the pattern is as he found it, and just outlined, or how much rock and plant was manipulated to arrive what we see in the photos.

And I wonder what image he would pull from the slope in Jeff's photo, if he were so inclined?

The artist who did what he calls "The hand of God and a Whale" is Francisco Hernandez Zamora aka Gerardo. His specialty is arte de la tierra. He is originally from Mexico City. He also did a big whale at San Ignacio Lagoon.

Lock formation...

EnsenadaDr - 9-24-2011 at 08:18 AM

I have always loved science, I loved astronomy as a kid and had a Gilbert chemistry kit when I was 6 years old..yeah go figure...anyways Geology was no exception...in college in the 80's (yeah I guess I am a professional student of sorts) I had a Geology class with a Japanese professor. we used to study as he put it, "Lock formation" (he couldn't pronounce the R!!) in the rolling hills of Connecticut.
You need to visit the Big Island of Hawaii where there are thousands of square miles of dried Lava flow that have have trees growing out of the rock, that's the place for Geology enthusiasts..anyways what was the first picture posted in this thread..is there something that you can see in the rock formation..I'm not getting a good resolution I think...

Roy Mahoff at Eco Mundo told me it is the work of Aliens.

About those trees growing out of the lava rock in Hawaii, some areas on the Big Island get lots of rain.;D

Ohia Trees

EnsenadaDr - 9-26-2011 at 06:03 AM

Oh I thought about the name of the only tree that can grow out of lava rock...it is called an Ohia tree...and rain on lava is akin to rain on cement...pretty hard to grow anything no matter how much water is there...
