Arches National Park located near Moab, Utah is just 7 hours from Denver on I-70
Fall Colors in great abundance  in the  Glenwood Canyon.
In the  Devil's Garden I did the hike  which was 4.2 miles and took  you to the Tunnel Arch, Pine Tree Arch,  Landscape Arch, Navajo Arch, Partition Arch and the furthest was Double "O" arch.

It took me approx. 4 hours to walk the whole thing. The weather was good until coming back and then the wind was blowing hard and cold.

Wall Arch
Double "O" Arch.  I had a hard time getting this all in the  frame and the sun was not cooperating either.
I saw lots of little lizards along the path.
Navajo Arch
Ouch!  Don't be sitting here!

Our Campsite was actually in Dead Horse Point State Park which is about 30 miles from Arches. 
Sunset at Deadhorse Point State Park - Lookout point.  
We had mostly rainy, windy cloudy weather at Deadhorse State  Park.
Despite the weather it was a fun trip and interesting.  The rock formations were very neat.  A return trip will have to be planned in the future.  The Arches were very cool. The new visitor center at Arches was  very informative.
Coming home on I-70 on the West side of Vail Pass we found snow and it progressively got worse as we got closer to Denver.
