Desert varnish grows much faster than geologists admit
by Michael J. Oard
Dozens of geological processes are commonly claimed to proceed too slowly for the short timescale of the Bible. Many of these claimed slow processes have attached dates of tens of thousands to millions of years.
However, we usually only hear one side of the origins issue. It is too easy to make a wrong decision based on only one opinion. We should investigate the other side of an issue, especially when one side is heavily censored in the public arena. We also need to be aware that there are numerous unknowns in the earth sciences, and that the addition of another variable can result in vastly different conclusions. Sometimes it is discovered that slow processes today can occur rapidly under different circumstances. Another aspect is that with more research, dating methods considered solid are found to be suspect. With this in mind, we now consider whether the ‘slow formation’ of desert varnish is correct.

Then there's dessert garnish.
Still awaiting the article about pumice so we can talk about the Mono Lake area.
PS: nobody goes to the White Mountains just for fun. There is no there there.

Could someone please explain to me what is meant by ‘desert varnish’?
Desert varnish or rock varnish is an orange-yellow to black coating found on exposed rock surfaces in arid environments. Desert varnish is usually around one micrometer thick and represents nanometre-scale layering.[1] Rock rust and desert patina are other terms which are also used for the condition, but less often.
Thanks! Your answer was much appreciated.
