We started our adventure in the Great Sand Dunes National Preserve in Colorado. These dunes cover about 39 square miles and reach to heights of 750 feet. They are the tallest sand dunes in North America. Bet you didn't know we had any sand dunes, much less ones this big in the United States.
Wolf Creek Pass, way up on the Great Divide.
Hovenweep buildings were built beginning
in the year 700 and abandoned around 1300.

Notice the Ruby Throat watching the Rufous over his shoulder.
It seems the Rufous was the bully of this group. He would
swoop down and peck the other's tails chasing them away from
the feeder. To see more hummers at this feeder, try this link.

Black Canyon of the Gunnison
That "tiny" river below had a flow rate while we were there of about 600 cfs
(cubic feet per second). During the spring floods, it can reach 12,000 cfs.
Notice the pegmatite intrusions in the rock face.
This formation called oil shale stone is
responsible for some of our oil related products.
Don't these petroglyphs look like aliens?
Goblin Valley - WOW look at those hoodoos!
Reminded me of hear-no-evil, see-no-evil and speak-no-evil.
