| Notice : | This square of 1m² was 'cleaned' in 1996 and revisited in 1999. Within 3 years, rainwash did evacuate the fines and a new desert pavement of lag deposits is developing. Note that the dark patina coating of the original stone pavement, sometimes called 'desert varnish', is still absent on the newly outcropping coarse fragments within the square. This detail shows the effect of runoff-creep of coarse debris: the white coloured 'new' pavement migrates downslope over the edge of the square cleaned in 1996. |
