[1] They are known as Confidence Hills for their formation of favorable flower structures, which are developed in Pliocene to recent lacustrine and alluvial sentiments.

The sediments’ plio-pleistocene of the confidence hills is located between two branches of the southern Death Valley fault zone.

In the Northern part, this central member exhibits less sand and more silt and clay-rich facies but still contain banded anhydrite.

A facies that contains the clasts of the volcano, primarily basalts, are interbedded with the member in the middle region of the Confidence Hills formation.

In this regard, the matrix is dark in color, which is similar to the clasts, and this indicates that it may have been derived from the same basaltic source (Mikus et al. 2019).The conglomerate appears to have been deposited in the southern part, the distal portion of a fan which grades laterally into streams reworked sediments.

These facies may correspond stratigraphically to layers with lenses of fine-grained sandy basaltic clasts in the southeastern canyons.

It is believed that confidence hills in the northern part at Shoreline could be a source of volcanic clasts( Mikus et al. 2019).

The large asymmetrical anticlinorium runs through the confidence hills, with its axis learning almost parallel to the south region's fault.

Studies have shown that there has been salt bloom after the heavy rains and some karst like topography exposition at the western end of canyons and the southern part of the Death Valley fault trace.

Notably, the Confidence Hills have been translated as forming through trans tensional due to the left step in the lateral fault in the right side, but this brings about the element into any tectonic interpretation (Tabush et al., C. 2020).
