SIERRA RANGE GENESIS, BY TIDAL SHOVE WEST TOWARDS MIDWAY ISLAND, ALONG 40N TRANSFORM

EARTH SCIENCE postings from www.googleearth.com are reported in blogsites in: www.PorOgle.blogspot.com for other locations.




Sierras act as a vertically-rotating semi-cylinder, with CCW SPIN looking NW.
The Sierra Range is entirely located in California, and essentially parallels the CA-NV border, separated from the line by the Death Valley NP. It is also bounded on the SW by the Central Valley, on the SE by the Garlock fault (which traces almost eastward), and by the Cascades on the NW. Mount Lassen active volcano defines the 40N latitude above which there is subduction and below which there are no active volcanoes. The Garlock fault location shows that this results from the movement of the Sierra-Central Valley system moving westward. It is my conclusion that the system is being shoved by the tidal force of the Moon to the west relative to surrounding lowlands. Below is a diagram of the S-CV system as it appears from space:

The first observation is that the Coriolis cells exhibit sharp valleys and shear features on the east side, but not on the west.
This is normal for all cells analyzed in the USA, where uplift, vulcanism, and higher elevations occur.


THE SOUTH SIDE OF THE SIERRAS ARE SHOWN- WHERE THE ACTION OF MAMMOTH HOT SPRINGS, E-W FAULTING, AND GREAT EARTHQUAKES ARE EXHIBITED:
ONE DIFFICULTY THAT MUST BE OVERCOME IS THAT OF THE ORIENTATION OF THE SIERRAS, VERSUS THAT OF THE LARAMIDE, WHEN IT WAS INITIATED. THE LARAMIDE MOVED EASTERLY OR POSSIBLY ENE, WHILE THE SIERRAS DO NOT ORIENT PERPENDICULAR TO THAT. EITHER THE SIERRAS HAVE ROTATED (WHICH, I THINK, HAVE NOT MOVED SUFFICIENTLY) OR THE CHAIN HAS BEEN INFLUENCED BY ANOTHER ENTITY. THERE ARE SOME FAINT TRANSFORMS IN THE OFFSHORE CA, WHICH INDICATE THAT THERE WAS AN ORIGINAL ENE MOVEMENT, AND THAT WOULD SOLVE THE PROBLEM- THE COMPRESSION WOULD HAVE INITIATED THE CHAIN, AND IF IT REMAINED TO THIS DAY (EXCEPT FOR MINOR ROTATIONS) THE CHAIN AND THE COASTLINE WOULD HAVE THE ORIGINAL ORIENTATION.

Assuming that the Sierras have rotated CCW (as shown by the larger distance along-Garlock fault- L.A. coast compared to Mendocino movement on the south side of the fault), then the transform oriented ENE toward the Coloma River, CA will approximate a perpendicular indication to the Sierras. This would agree with the general movement of the Laramide to the ENE, creating the orientation of the Sierras in their present configuration (allowing for some CCW rotation since their inception.
ASSUMING THAT THE AMERICAN, LAST, AND COLOMA RIVERS YIELD TRACES, WHICH WERE CREATED PRE- AND POST-TERTIARY TIMES, THE ROTATION OF THE SIERRAS MAY BE SEEN AS apprx.10 DEGREES CCW. THIS IS SIGNIFICANT, BUT INDICATES THAT THE LARAMIDE ORIENTATION OF THE CHAIN IS CLOSE TO THE ORIGINAL AT 65 M.Y. AND THAT THE ROTATION HAS PROCEEDED BY CORIOLIS ACTION ON THE WHOLE RANGE. WE NOW MUST DETERMINE WHETHER THE ACTION OCCURRED AT THE SAME TIME AS THE ROCKY MT. SHOVE- BUT DISPLACED BY MORE THAN 1000 KM. THIS SEEMS UNLIKELY, BUT IT MAY BE THAT SIMULTANEOUS SHOVES TO THE EAST OCCURRED (THIS ELIMINATES THE NEVADAN AND SEVIER OROGENIES FROM CONSIDERATION AS BEING PREPARATORY TO THE LARAMIDE SHOVE TO THE EAST- AT A LATER TIME- SINCE THE KT STRIKE REPRESENTS A MAJOR DISCONTINUITY IN ETHE PROGRESSION). WHY AM I SELECTING THE AMERICAN RIVER AS THE YOUNGEST AND THEREFOR THE ONE INDICATING PRESENT REFERENCE? BECAUSE THE AMERICAN IS ORTHOGONAL TO THE PRESENT SIERRAS, AND THE COLOMA IS NOT, ADDITIONALLY, THE COLOMA TRACE IN THE PACIFIC BASIN IS THE FAINTEST.
Looking again at the Mendocino location, we see why the part south of the cape moves westward, while the part north moves eastward:

Hurricane AIRPORT, FROG HOLLOW CANYON ANOMALY

EARTH SCIENCE postings from www.googleearth.com are reported in blogsites in: www.PorOgle.blogspot.com for other locations.
Hurricane Airport Canyon, or Frog Hollow
Five kilometers south of the town of Hurricane, the local airport is located within a half km. of Frog Hollow- a canyon which can be hiked for a few hundred meters (before reaching a dead end box canyon). This location is shown in the following Google Earth photo: Hiking to the box from the airport road side of Hf:

The Hurricane fault, Hf, traces NNE-SSW in this area, similar to the fracture pattern noted on the Colorado Plateau, CP, side of Hf. The airport is on level land- Basin and Range, B&R, with eroded Mesozoic rock, while CP exhibits Paleozoic limestones. The scarp between these is about 200 meters in height, not representative of Hf to the north of Laverkin- which may reach 300 meters. As may be seen in the photo, the canyons are arcuate, or circular as is common for Coriolis-influenced shear about Hf. I have explained this as due to CP moving CCW (rising)- which would be to the south on the high side of the scarp. Since there is a differential in movement on the two sides of Hf, the Coriolis effect causes a movement to the right- that is, a CCW portrait of the canyon (the same CCW rotation as CP). This might be considered a reactionary cell, RC, where the rock uphill merely rotates in reaction to the drag of Hf (in harmony with the rotation of CP- creating NO HEAT SUFFICIENT FOR VULCANISM). We will check any seeps found to see whether there is a temperature rise due to BRITTLE ROCK FRICTION. This may be compared to weather cells, in this case to HIGH PRESSURE CELLS OF FAIR SKIES, where the high pressured air move outwardly and when moving to the right creates a CW Cell. THE CW MOVEMENT IS A SINKING FEATURE- WHICH CREATES CLEAR SKIES, BY COMPRESSION (IN CONTRAST TO A RISING FEATURE, CCW, OR LOW PRESSURE WITH BAD WEATHER) Think of the rock as rising (above the Hurricane Valley,) which is moved to the right- hence making a CCW trace as it encircles the upwardly-moving segment of crust.
Below is a traverse made on top of the TOPOGRAPHY- A DISTANCE OF 3/4 KM:
The feature, which we will investigate further, is the ellipse which lies within the cell of ¾ km diameter. I have found that larger features iminging on other larger ones tend to form an ellipse when constrained by the two features. In this case, it appears that the ellipse is dominated by the local fracture pattern, but field evidence may shed some light on the dynamics of this secondary feature. We will measure seep temperature, fracture and fault orientation, dips, and tilt of the entire feature, and this may require a hike above Hf as well as into the canyon. We will seek slickensides to authenticate the direction of lateral faulting, and get photos of unusual anomalies.
After hiking Frog Hollow again, some photos of anomalies are shown below: TRAVERTINE IS FORMED AS FOLLOWS: SURROUNDING LIMESTONE BEDS SUBJECT TO SHEAR PRESSURE OF ROTATING CELLS DISSOLVES (SOLUBILITY INCREASES WITH INCREASING PRESSURE AND LOWERING TEMPERATURE). WHEN AN OPENING OR VUG IS ENCOUNTERED, THE PRESSURE DROPS AND THE DISSOLVED IONS DROP OUT AS TRAVERTINE. THIS IS A FIRST STEP IN FORMING SLICKENSIDES, EXCEPT THAT SILICA MUST BE DISSOLVED WITH INCREASING PRESSURE. TEMPERATURE IS A FACTOR, BUT THE DOMINATING FACTOR IN THE P, c, T SYSTEM IS P. COMPOSITION MAY ALSO CHANGE, AND FOR SILICA VERSUS DISSOLVED LIME, THE SILICA REPLACES THE LIMESTONE AS PRESSURE DROPS- FORMING A SILICATE HARD-FACE ON THE LIMESTONE.
Below is a photo of the area analyzed further:
A hike to the east side of Hf yielded a box canyon, below which we could not descend. There is an excellent half-spiral in the Frog wash, with obvious spalling on the north side, rotating CW (a sink), and with measurable dip and tilt to the Coriolis cell. The general dip of sedimentary beds is toward the Virgin river to the north about 2 degrees, but the local basalt found in the Frog Hollow has flowed in the opposite direction- to the south, terminating in the walls of the wash.GOULD'S WASH- CANYON TO NORTH OF FROG HOLLOW



NEXT WE WILL EXPLORE THE CANYON TO THE NORTH OF FROG HOLLOW, STARTING WITH THE ENTRY INTO THE VIRGIN RIVER- JUST NORTH OF THE SKY MOUNTAIN GOLF CURSE IN HURRICANE. THEN WE WILL PROCEED UPSTREAM TO NOTE THE BASALT WALLS AND THE TURN TO THE RIGHT TOWARDS THE HURRICANE CLIFFS- WHERE IT FORMS A BOX CANYON:

NEXT IS A HIKE INTO GOULD'S CANYON ON THE UPSIDE OF Hf:


LOOKING TO THE SOUTH OF GOULD'S, THERE IS A BASALTIC PLATEAU WHICH YIELDS THE FLOW ENTERING FROG HOLLOW- FROM THE SOUTH?
I HAD THOUGHT THAT GOULD'S WASH AND FROG HOLLOW WERE PART OF THE GRASS VALLEY CELL (since they were within the 30 km configuration); HOWEVER, THEIR CELLS EXIST EAST OF Hf, AND THEY ARE SEPARATE, AS SHOWN BY THE FOLLOWING TWO DIAGRAMS:

YOU CAN SEE THAT THERE ARE FOUR CANYONS, INCLUDING THE FORT PIERCE WASH, BUT FROG HOLLOW AND GOULD'S WASH ARE NOT PART; WE MUST DETERMINE WHAT IS THE VULCANISM ASSOCIATED WITH THEIR ROTATION.
NOTE THAT THERE IS NO BASALT RIM SOUTH OF GOULD'S, BUT IT IS PLENTIFUL AS A RIM TO THE NORTH. FURTHER, THE CIRCULAR FEATURE IS ENTIRELY ON THE EAST SIDE OF Hf.THIS MEANS THAT THE CELL IS A REACTIONARY CELL (DRAG) AND NOT FORMED BY VULCANISM:
THE LARGER VIEW SHOWS GOOSEBERRY MESA TO THE EAST, WHICH WE WILL HIKE THIS SPRING:
TO BE CONTINUED, WITH HIKING AND FURTHER ANALYSIS OF THE ANOMALY.

Hurricane Fault Arcuate feature at AZ border similar to Aleutian Spiral




This is subject to pulses approximately each 200 k.years, as is seen in the above photo, and at the Kolob Mesa just north of Virgin Town.

Adjacent to dynamic features is a cell I have named a REACTIONARY CELL, RC. This is shown below for the zone north of the western Aleutians, which is a CW-ROTATING cell, with a diameter of 300 km.

The direction can be determined by use of GPS data, knowing that the entire Aleutian chain is moving toward the SW, and that the crust is being dragged along with the general rotation (on the north side). A similar small-scale feature is shown below in a digital photo, of Hf near the AZ border, with the diameter on the order of 1 km:

SPIRAL GEOMETRY CALCULATIONS
The case of the Hurricane Fault at the AZ border is valuable for determining the rate of movement and cell boundaries. This is the third (or possibly fourth) of concentric spirals about the Grass Valley vulcanism- which triggered the rotations about Hf, and which left an arcuate path for the Virgin River.
First let’s review the evidence, to determine which rotating cells are pertinent to the study of this DISCOVERY CASE. There are several concentric circles, or circular traces, fitting within the feature extending from the WA fault in Washington City to Virgin Town. This will not include the Fort Pierce Wash trace which has vulcanism on its southern border in AZ- which proceeds to the intersection with the Virgin River at Santa Clara (which has a triple junction with the SC River on the north side of the Virgin).
These Coriolis cells, rotating about Hf, proceed Clockwise, CW, as determined by the direction of lateral thrusting and cat steps in slickensides. This is for cooling cells which shrink and sink with a CW motion- the opposite of magma rising, which rotates CCW for uplifting features. This was solved for the geometry noticed in the Laverkin Sink and graben- where occur slickensides at an angle indicating that the Colorado Plateau, CP, is moving CCW (while presenting rising). The rate of moving there as evidenced by the trigonometry of the slickensides resulted in the lateral movement being about 1/3rd of the vertical movement- yielding about 1.5 mm/year lateral movement for 5 mm/year vertical faulting. Overall, this displacement has been calculated to be about .2 mm/year, but there is an occasional surge of displacement (indicated by terraces) of faster movement.
NOTICE IN THE ABOVE PHOTO, THAT GYPSUM, FROM THE MESOZOIC, HAS BEEN TRANSPORTED UPHILL INTO THE PALEOZOIC rubble about a kilometer. THIS ALLOWS THE RATE OF MOVEMENT TO BE CALCULATED (ABOUT 1 MM/YEAR)
The circumference of this local spiral is about 4 km, as indicated by Google Earth’s horizontal measurements, This calculates that the diameter is about 1.3 km, and for a Grass Valley age of about 1 m.y. There is a rotational velocity of 1 mm/year movement along the E-W canyon wall. This is predicated upon the observed strand OF FRACTURES along the minor canyon of about 1 km. This circular reactionary movement has now reached uphill about a similar distance- forming a slight canyon (with a noticeable spur or splay) which becomes less obvious up the hill above Hf.\
This is all presented in a DIAGRAM- SHOWING THE IMPORTANT MOVEMENTS. NOTICE THAT THE MANTLE MAY BE ROTATING THE BASE OF THE CRUST TO THE EAST (yielding the tilt of the surface beds): Below is another view of the encircling fracture system, actuated by the moving and cooling GRASS VALLEY VULCANISM;
THE CLOSEST CANYON TO THE TOWN OF HURRICANE AND ITS THREE VOLCANIC CRATERS IS LOCATED JUST EAST OF THE HURRICANE AIRPORT. THIS CANYON DOESN'T ALLOW ACCESS TO CP, AS IT IS TOO STEEP TO CLIMB. IT DOES SHOW SIGNIFICANT FRACTURES AND FAULTING, AND WILL BE ANALYZED BELOW:

PEAR-SHAPED EARTH: Bulges due to the WOBBLE OF THE EARTH-MOON SYSTEM as it rotates about the Center of Mass annually on the ECLIPTIC

ABOVE IS A SPECULATIVE SOUTH PACIFIC VIEW. WE WILL DETERMINE WHETHER ANY OF THESE PROJECTINS ARE TRUE, BY COMPARISON WITH FOSSIL TRACES FROM OTHER REGIONS.
THE EARTH-LUNAR WOBBLE ABOUT THE ECLIPTIC IS SHOWN ABOVE, WITH THE PEAR-SHAPED EARTH PRESENTED BELOW:

ABOVE IS A DIAGRAM OF THE EARTH, SHOWING HOW A SLIGHT BULGE EXISTS, IN ADDITION TO THE GREAT EQUATORIAL BULGE. WE WILL TRY TO FIND WHAT CREATES THIS CIRCUM-EQUATOR FEATURE: FROM THE MOON ATTRACTION DUE TO ITS 5.1 DEGREE ANGLE TO THE ECLIPTIC, OR TO THE SUN, OR A COMBINATION OF BOTH? BELOW SHOWS HOW IT IS INVOLVED IN THE FORMATION OF ISLANDS IN THE SOUTH PACIFIC:

PEAR-SHAPED EARTH: Bulges due to the WOBBLE OF THE EARTH-MOON SYSTEM as it rotates about the Center of Mass annually on the ECLIPTIC
It is my experience that the CRUST OF THE EARTH is dominated by Coriolis rotations- creating most of the STRUCTURAL GEOLOGY ANOMALIES. There is another influence by the MANTLE, WHICH ROTATES SLIGHTLY FASTER THAN THE CRUST, and which causes the crust to rotate vertically, along mostly horizontally-oriented circular cells-near the coastlines (where it is relatively unconstrained by the shallow oceanic thin crust). There are other factors which I have isolated:
1. Shear developed at the 40N and 40S latitudes, where the crust at higher latitudes moves relatively slower compared to the tidal shove to the west for BULGES (such as mountain ranges and other protrusions);
2. Compression, due to shrinking with time of the earth’s sphere, which probably creates (by lateral squeezing) the mountain ranges parallel to bodies of water;
3. Pulsing of the magnetic field, which creates cycles of increased activity every 200 k.years or so; and,
4. Mechanical shock from asteroids or meteors, which creates craters and antipodal bulges on opposing sides of the earth.
Should the comments on the Coriolis influence be correct, the projections can be checked independently, via the presentation of the earth’s hemisphere by photos from space satellites. Weather cells are conceded to be influenced only by Coriolis rotation and the friction with the earth’ surface- changing daily because of SOLAR HEATING, DIFFERENTIAL VELOCITIES BETWEEN LATITUDE LINES, AND PROTRUSIONS INTO THE ATMOSPHERE BY HILLS OR ISLANDS, MOUNTAINS, AND GLACIERS.
SIMILARLY TO THE ATMOSPHERE BEING DRAGGED BY THE EARTH’S SURFACE, THE CRUST IS BEING DRAGGED BY THE UNDERLYING MANTLE.
Should this analogy be sufficient, one has only to observe the positioning and movement of weather cells to find the concomitant influence on island chains, seamounts, and sea bottom. For example, the South Pacific islands are a relatively elevated area of crust which create a diversion of weather around them. This is seen as a circular development of high clouds, somewhat independent of the weather-making low clouds. High clouds can be seen to derive from the north Pacific, to cross the Equator, and to ride over the weather-making clouds in the South Pacific. Coriolis force has not impeded the clouds from crossing the Equator- as is the case for weather cells and clouds (which cannot cross, because of the fastest velocity barrier existing there) .
It is my tentative conclusion that the Mantle, plumes, hotspots, and the Core have little else to do with the Crustal movements, except possibly for the metal-influencing cycles of pulsing and the magnetic cycling noticed each 200 k.years of so. If one can determine the dominant Coriolis Effect’s incipience of weather cells, then one can find that this will be reflected in the rotation and positioning of islands and other masses in the Pacific Ocean.
The first clue is the over-riding of the high clouds, which evidently are determined by the return circulation of the atmosphere to renew the lower rotations (weather clouds). This may be determined by the shape of the PEAR-SHAPED EARTH, AS IT IS CREATED BY THE INFLUENCE OF THE MON, SUN, TIDES, AND THEIR SEASONAL CHANGES.
How is it that the Mantle is not involved in Crustal manifestations, other than by pushing the base of the crust to the east? I have proved this to myself, by viewing the simplest features in ocean bottoms, where there is a thin crust (5 km or so). For these cases, there is the Pacific Hourglass, which is a feature of seamounts, islands, and craters, that forms a symmetrical exhibit over thousand of kilometers. When one dissects this hourglass, it is found that it is composed of the boundaries of circular arrangement of vents and islands, which shear and heat from vulcanism due to rotating crust. See the following photo of the northern Pacific:

VIEWING THE HOURGLASS IN MORE DETAIL: Below is a view of a transitory hourglass from a weather satellite, indicating that Coriolis affects weather similarly to the earth's CRUST click on the center button, if there is no picture!
AND INDEED, THE FEATURE HAS NO INDICATION OF PLATES, MANTLE PLUMES, OR ANYTHING BUT ROTATION OF CORIOLIS CELLS, UNTIL REACHING THE EQUATOR.


THIS MAY BE ANALYZED SEVERAL WAYS- ONE: COMPARE THE ZONE TO WEATHER CELLS WHICH ARE IN THREE 30 DEGREE BANDS:
TWO: ANOTHER ANALYSIS INVOLVES LOOKING AT THE DETAILS OF THE VARIOUS CELLS- NOTICING THAT THERE IS NO CORIOLIS EFFECT AT THE EQUATOR (LATITUDINAL VELOCITY REFERENCED TO SPACE IS MAXIMUM THERE):

BELOW IS THE HOURGLASS PORTRAYED BY LOW ALTITUDE CLOUDS, WHICH IS DETERMINED BY CORIOLIS FORCES IN THE ATMOSPHERE. ALSO THERE IS A HINT OF A SOLUTION TO THE ALMOST-LINEAR FEATURE CROSSING THE EQUATOR- THAT THE SUN'S HEATING IS A "USUAL SUSPECT".
Summer Heating: Part of the Solution of the Reason for the Seamount chain along the Tropic of Capricorn
There occur several obvious sets of fissures or seafloor features which trace along the South Atlantic Basin. These remain a puzzle, since they cross the Equator before arriving off the coast of South America. However, the above Photo from Space, using satellite images, indicates that clouds form in patterns prompted by SOLAR HEATING. Obviously, this changes hourly throughout the day, but there is a caveat to all this: the ocean basin is almost a closed system, and this constrains the movement of clouds (and ocean water and earth crust, for that matter). Further, the spinning earth forces mass in both hemispheres to move to the east, and that is constrained by the coastlines of the Americas.
Most locations of the earth experience two dominant wind patterns. In my dwellings, there is a north wind in the winter (irritatingly blasting, for noticeable cycles), and a SW wind in the summer and most of the rest of the year. This also occurs in movements of the Crust for the area: the trough along the great I-15 fault moves southward until arriving at the divergent zone at the Hurricane Fault. After that the winds proceed along the two divergent low areas. (the pertinent rule for EARTH SCIENTISTS IS: FOR EVERY SADDLE THERE’S A FAULT). In the summer, the winds follow the movement along the Virgin River- which is from the SW, the same direction as the Virgin rotation to the NE and finally Eastward.

THIS IS SHOWN FOR THE HURRICANE AREA, INCLUDING THE SOUTHERLY MOVING CP AT THE HURRICANE FAULT, AND FOR THE CCW-ROTATING (FROM THE SW) FAULT ALONG THE VIRGIN RIVER:
When I recalled all of my other locations, where I lived significantly enough to memorize the wind patterns, they had two patterns also. Houston had the SE winds, alternating with the BLUE NORTHERS, and this is the pattern for the crustal rotations. The CW rotation of the Gulf Coast and the Northwest to SE patterns of the circular river valleys.

BELOW IS AN EARTH VIEW FROM A SPACE SATELLITE. NOTICE THAT EL NINO IS NOW ABSENT (FEBRUARY), BUT THAT OTHER HIGH CLOUDS FROM NOON-TIME HEATING ARE CROSSING THE EQUATOR: OTHER FEATURES ARE SEEN FROM THE SPACE LOCATION:
1. WEATHER CLOUDS ARE EASILY TRANSITED BY HIGH CLOUDS.
2. THERE IS A DISCONTINUITY AT THE 40S LATITUDE;
3. THE SOUTH PACIFIC ISLANDS ARE ISOLATED FROM THE ENCIRCLING HIGH CLOUDS (PROBABLY BECAUSE THEY REPRESENT A HILL WHICH CAN BE BY-PASSED); AND.
4.THE WEST INDIES HAVE THEIR OWN CIRCULATIONS, BECAUSE OF THE HIGH TERRAIN- WHICH IS PROBABLY FORMED BY THE BULGES DEVELOPED BY CELL CONFLICTS CREATING THE VULCANISM TO THE EAST.
