alluvials in rock Alluvium (from the Latin alluvius, from alluere, "to wash against") is loose, unconsolidated (not cemented together into a solid rock) soil or sediments, which has been eroded, reshaped by water in some form, and redeposited in a non-marine setting. en.wikipedia.org/wiki/Alluvium |

His file is named "rock of colours"..
I don't think the colours exist in the rock.
The bright tan area is quirk of imagery production, it doesn't actually exist.
When I went through the history of Google's images for the area, it looks normal, and then it looks white like snow.
I think its from a photo that showed the terrain very well, but the sun was to the east ,and the camera, ground and sun at the right angle, and so it showed all but steep west facing slopes as bright ... the steep west slopes, of far lesser area, are dark.
The trouble is that google's images for one time in the history may or may not be a revision (the best stitching produced) not a replacement (not the raw input before stitching)
I think that the bright sun spot image then gets averaged in to the revisions over time.. becoming more tan than white over time.
