 From Utah Highway 10 near Castle Dale to US Highway 6 near Woodside.

The Green River Cut-Off crosses or briefly runs along two of Utah's historic routes: The Old Spanish Trail and the original route of the Denver and Rio Grande Western (DRGW) Railroad. It is often difficult to find the specific route of the Old Spanish Trail as it is now mostly worn away. However, it did go through much the same area as the Green River Cut-Off trail. The original D&RGW roadbed is a bit more defined (though still worn away) and crosses paths with the Green River Cut-Off in several places.

Little Cedar Mountain to the North.

On the eastern slopes of Little Cedar MountainNear this location are paleosol collection sites in the Morrison and Cedar Mountain Formations used by Retallack in his 2009 study of greenhouse crises of the past 300 million years. Retallack used stomatal index data for fossil Ginko and related leaves as a proxy for past CO2 spikes and paleosol chemical data as proxies for temperature and humidity changes. These data show that global warming due to CO2 rise is a not a unique event in earth history and that the magnitude of the coming anthropogenic greenhouse pales in comparison with past greenhouse spikes at times of global mass extinctions.

Subject: Re: Question about San Rafael Swell -- Summerville Point Date: Wed, 8 Oct 2008 22:17:06 -0600 From: To: Tom Schweich References: <48EC152D.8090206@schweich.com> Tom, Our information places Summerville Point at or about 39.183335 -110.463349. At least it is on this ridge. Access to the ridge can be found from a spur off the cut off road on Dry Mesa. This is a rough ATV road but well worth the view to be had. Feel free to e-mail pictures of the area. I looked around and I have not been able to find any in our files. --Gary Wulfenstein
