This clue was a nicely-printed brochure about Valley of Fire State Park.
Below is the text-only contents of the brochure. This is sufficient for you
to try out the puzzle if you don't want to load and print the whole brochure JPGs.
The Valley of Fire is a quiet treasure shared by the people, a bizarrely
magical rock jigsaw that excites us all. A loop road allows visitors to go by
rock formations such as Juxtal Rock, a quartz outcropping popular with
artists. Brave pioneers journeying in covered wagons to the area remarked on
the quirky formations, seeing foxes, birds, an entire zoo. Exciting Indian art
abounds, such as drawings of quite cunning sheathed primitive spears and
tricky jars used to capture buzzing insects. People who explore the rocks,
however, should beware of quarrelsome cougars; though they appear lazy, they
may suddenly jump.
Early people inhabiting the Valley of Fire, including the Jicaque, Loucheux,
and Kawchottzine, farmed corn and hunted. Such people were great travelers
because water was scarce; we conjecture that area aquifers may mark the path
of their amazing explorations. Present-day Valley inhabitants consist of a
large variety of mixed wildlife, like lizards (Anniella iraqensis) and
jackrabbits. The flora explodes early each year as the Valley fills with a
bouquet of azalea, Jerusalem artichoke, sweetflag...
Many famous artists found inspiration in this vicinity; G. Q. Zachowsky did
"Brown Jackal with Waxbill" in 1879. The unorthodox Bracque, on a trip through
the Valley, immortalized the view in the "junk painting" technique of the
early twentieth century. Quick-moving, dazzling daylight and waxing moonlight
both stir visitors who find joy in photography.
The Valley's camping facilities, judged "superb" by the Sun, await---but those
who seek sanitized toilets will find Las Vegas equally convenient. There are
many ways to access campgrounds around the park; you may be justly vexed by
the rush of cars, but the roads can accommodate the squeeze. Once inside, you
will quickly find picnic areas behind every major campground, where you can
socialize and relax. You cannot carry alcohol or guns on park grounds, nor
burn waxy junk such as matanzas wood or quackgrass.
As you look upon your sojourn you may carry away an album or canvas of your
own, full of lynx, buzzards, squally cloud forms or flora all abloom.
