On the Road: Geo-challenge 2

Where are we now?  View is from behind, as the sun sets.Plants & Rocks is still on on the road and finding it hard to blog, so here’s another quick geo-challenge.  The first was the geologically very cool Uinta uplift; more on that later.  Then I visited a another Laramide range.  This one has an unmistakable east flank – too easy for a geo-challenge.  Instead, here are views “from behind”.
Sandstone cliffs in evening light with a laccolith in the distance.Another laccolith on the right horizon – in fact the type locality.Morning view.  The large mesa to the southwest is capped with volcanic rocks.In the “high country”.  No Precambrian rock is exposed, and the vegetation is piñon-juniper woodland.
