return to Muara Crater Overview

     There are no white layers in the following two photos from
the North crater wall.  They are close views of the lowest portion
of the crater just above the crater floor.  The value of these
photos is they show the nature of erosion and deposition within
this area prior to the deposition of the white mineral layer.

This view shows cross bedding.

A very good example of an unconformity formed by major
erosion, followed by deposition upon the eroded surface.
width of view: 294 feet
