Seeking Slickensides along the Great Basin and Range Lateral fault at the Virgin River


Above is a Google photo of part of the Virgin River- leading to Overton Arm of Lake Mead, NV and below is the area hiked for details, such as slickensides and river diversions and meanders, caused by lateral Coriolis rotation:

Oh, The Buzzing of the Bees and the Joshua Trees,
The Soda Water Fountain,
Where the Lemonade Springs, and the Blue Bird sings,
At the Big Rock Candy Mountain.


It is enough to make one burst out in song, to hike the great features of the West- along the Beaver Dam Mountains and the babbling Virgin River. And indeed our group did just that today, on the Trek along the canyons and sheer slopes of the BDM off I-15 near the Cedar Pocket Park.
This is BEAUTIFUL COUNTRY! Although there was snow in the distance, the climb was exhilarating up the road to Beaver Dam Mountains. Surprisingly, there is a good gravel road into the high country, north of the Freeway. Walking only 2 kilometers, we were flush with LIFE- enjoying the false Spring after the recent snows. And the trip was not just for indulgence of Fall days- we found many GEO-features, which were rewards for “toning up” octogenarian muscles and attitudes. LIFE IS GOOD!
The photo above reveals considerable information about the trek made- where one can readily find what is occurring with the DYNAMICS OF THE EARTH. This is enhanced by walking in an area which is pregnant with sinks and uplifts- where the actively-moving B&R lateral fault inscribed about most of the state of Nevada and part of Utah left its mark. Quite confidently, the lateral fault is moving CRUST southwest on the north side of the Virgin- where the Virgin itself is the result of the shear transpiring along this roughly circular path. All of the preceding analyses leads one to surmise that there would be HEAT FROM BRITTLE ROCK FRICTION developing along this path. But this is not the case, since there are buffering cells of Crust rotating in harmony with the B&R fault, counter-rotating against those at the Virgin river. Notice that cells adjoining the Virgin river are rotating CW on the NW side (similar to the B&R), and rotating oppositely on the SE side of the river. Two gears rotating side by side, meshing together while rotating in opposite directions, are in harmony- producing no heat (with proper lubrication by the river of course!). Conversely, should two cells both rotate in the same mode, CW vs. CW, there will be Hot Springs, geothermal areas, or vulcanism. This is the case for the B&R fault near the towns of Hurricane and Laverkin- where several vents have occurred, and where Pah Tempe Hot Springs still tells the story that friction is occurring at a shallow depth. The Earth will tell us when there is CONFLICT OR DISHARMONY, with appearance of an anomaly of some sort. And of course, this is the goal of all Earth science workers- to find an anomaly, which will pay for his upkeep. GAIA only reimburses those with finders of the KEY TO THE CODE! And here are the first few rules:
1. Coriolis rotation produces the most common anomalies throughout the crust- CW implies sinking in the Northern Hemisphere, while CCW rotation indicates uplift;
2. The termination of the Equatorial bulge at 40N or 40S Latitudes, produces shear and displacement of geological features laterally;
3. Circular River paths, slickensides with lateral striations, shearing of concrete slabs horizontally, dragging of river banks and loops in the form of anomalous meanders and cliffs, and linear fracture patterns all yield clues as to the dynamic activity of the Crust; and,
4. Dipping or tilting of sedimentary beds, along with the direction of dip, tells a subtle story of vertical rotation of Coriolis cells within the Crust.
5. Interestingly, some Coriolis cells posses a centerline, allowing one to determine the outer circumference as a check of one's appraisals. Others, such as the Double Thrusts of the Valley of Fire, NV, have rotations between the two linears.

A sixth rule, that of cycling of the movements of the Crust, is still under analysis. It seems that the Magnetic Polarity reversal, producing spreading of the Mid-Atlantic Ridge, is happening near anomalies also. This is noticed for the cycled benches at the Hurricane Fault, Hf, as successively-rising terraces going eastward back in time. The cycling time spread is on the order of something less than a million years- 220,000 years apart for the Hf terraces.
The slickensides in limestone walls within one mile of I-15 Freeway and the Cedar Pocket Park are on the south wall of a sinking cell, and show some "cat steps" or indications of rotation direction:


The next story told by the Coriolis cells agrees with the adage: "For Every Valley there's a stream, and for EVERY SADDLE THERE'S A FAULT". In the below photo, the slickensides (indicating a lateral fault), with a bit of curvature, align with the Saddle to the south- "rounding out" the presentation:
Before we proceed down the Virgin to the Overton Arm TRIPLE JUNCTION, view a smaller TJ at the intersection of the Santa Clara and Virgin Rivers: Expanding the Santa Clara- Virgin junction (A TRIPLE JUNCTION, WHERE TWO ROTATIONS MERGE), there are a number of anomalies which we will investigate, by hiking in the area:
