These photo pairs of the
Roberts Mountains were taken in early May and early August from not quite identical points along the Tonkin road in what amounts to the southern part of Pine Valley in north-central Nevada.
Roberts Creek Mountain is the highest peak in the first photo pair.
The rocky foreridge in the second photo pair is underlain by the Ordovician
Eureka Quartzite, with various Ordovician through Devonian carbonate formations above the quartzite and various Cambrian through Ordovician formations below it.
A little geology.
Yeah, it was quite smoky when I drove through last week — and probably still is — with this particular batch of smoke coming primarily from the Ferguson fire in Yosemite.
Photos taken 1May2018 and 4Aug2018.
