I love well-behaved spiders! They are, in fact, how most people find my site. Unfortunately, my network has a limited bandwidth and pictures take up bandwidth. Spiders ask for lots and lots of pages and chew up lots and lots of bandwidth which slows things down considerably for regular folk. To counter this, you'll see all the text on the page but the images are being suppressed. Also, some system options like merges are being blocked for you.
Note: Permission is NOT granted for spiders, robots, etc to use the site for AI-generation purposes. I'm sure you're thrilled by your ability to make revenue from my work but there's nothing in that for my human users or for me.
If you are in fact human, please email me at guthrie.bruce@gmail.com and I can check if your designation was made in error. Given your number of hits, that's unlikely but what the hell.

Specific picture descriptions: Photos above with "i" icons next to the bracketed sequence numbers (e.g. "[1] ") are described as follows:
DINO_030526_004_STITCH.JPG: This image is important because it illustrates what remains (the grey area) vs what the paleontologists removed through the years (the orange area). You can see the bulk of the site is long gone, occupying natural history museums around the world, and you are left with just remnants but they are amazing remnants.
DINO_030526_005_STITCH.JPG: This is the area that remains. Most of the pieces that you can see in the wall are identified here.
DINO_030526_023.JPG: This was a land formation near the visitor center. Nope! That's not the spine of an ancient dinosaur; it's just tilted sedimentary rock which has eroded at different speeds. But it's still impressive.
DINO_030526_043.JPG: This and the next picture locate a camarasaurus in the rock. There are close-ups of the head later on. As the sign points out, the bones frequently get shifted as the water deposits the silt so pieces may end up scattered. The spinal columns are fascinating.
DINO_030526_069.JPG: Dinosaur National Monument
DINO_030526_100.JPG: This is the head of the camarasaurus. You can see the teeth in his mouth. Very cool!
DINO_030526_118.JPG: The dinosaur in front of the visitor center is 40 years old. A sign describes it as such: "A Historic Dinosaur: Do you recognize this Stegosaurus replica? If you had been to the 1964 World's Fair in New York City, you might. It was the first of nine life-sized dinosaurs created for Sinclair Oil Corporation's Dinoland exhibit. In 1970, the replica was donated to Dinosaur National Monument where it continues to greet visitors from around the world."
DINO_030526_138.JPG: This is the Yampa River.
DINO_030526_139.JPG: The visitor center itself preserves the dinosaur quarry which you can see on the right side of the building. A sign on the building describes it as such: "This building has won nationwide recognition for its style and set a new style standard for the National Park Service. Today it is on the National Register of Historic Structures.
"From the Great Depression to the 1950's, the dinosaur quarry was housed in a corrugated metal shed. In the mid-1950's, the National Park Service embarked on a project to upgrade park facilities to meet increasing visitation.
"The architect designed this building to enclose the fossil-bearing cliff and blend with the environment. The soaring 'butterfly' roof was to blend with the tilted formations, open glass areas took advantage of natural light and the surrounding vistas. The upper gallery walkway brought visitors close to the cliff and provided a dramatic, sweeping view of the dinosaur fossils.
"While debate surges around dinosaurs the structure encloses, so too it swirls around the building. It was built on expansive soils before construction techniques could adequately compensate for surface and subsurface movement."
DINO_030526_152.JPG: Bruce Guthrie @ Dinosaur National Park
DINO_030526_166.JPG: The guess is that the group in the upper left indicates "family".
DINO_030526_167.JPG: The figure at the top is supposed to represent either a mountain lion clan symbol or an all-powerful animal spirit that watches over things. The figure on the bottom looks like a horned-toad to me but it could be anything.
DINO_030526_169.JPG: I'm guessing this is something like elk but who knows
DINO_030526_239.JPG: I don't know what this represents but I imagine the little dots are buckshot.
DINO_030526_249.JPG: Figures shown upside down usually represent dead figures so this looks like a guy who's killed a deer.
DINO_030526_290.JPG: Dinosaur National Monument
DINO_030526_304.JPG: The scribble at the bottom indicates white trash passed through this area. There should be signs saying "Please sterilize me" on some people.

Wikipedia Description: Dinosaur National Monument
From Wikipedia, the free encyclopedia
Dinosaur National Monument is a U.S. National Monument located on the southeast flank of the Uinta Mountains on the border between the American states of Colorado and Utah at the confluence of the Green and Yampa Rivers. Although most of the monument area is in Moffat County, Colorado, the Dinosaur Quarry is located in Utah just to the north of the town of Jensen, Utah. The nearest communities are Vernal, Utah and Dinosaur, Colorado. This park has fossils of dinosaurs including Allosaurus and various long-neck, long-tail sauropods.
Geology:
The rock layer enclosing the fossils is a sandstone and conglomerate bed of alluvial or river bed origin known as the Morrison Formation from the Jurassic Period some 150 million years old. The dinosaurs and other ancient animals were washed into the area and buried presumably during flooding events. The pile of sediments were later buried and lithified into solid rock. The rock layers were later uplifted and tilted to their present angle by the mountain building forces that formed the Uintas. The relentless forces of erosion exposed the layers at the surface to be found by paleontologists.

History:
The dinosaur fossil beds (bone beds) were discovered in 1909 by Earl Douglass, a paleontologist working and collecting for the Carnegie Museum. He excavated thousands of fossils and shipped them back to the museum in Pittsburgh, Pennsylvania for study and display. President Woodrow Wilson proclaimed the dinosaur beds as Dinosaur National Monument in 1915. The monument boundaries were expanded in 1938 from the original 80-acre tract surrounding the dinosaur quarry in Utah, to its present extent of over 200,000 acres (800 kmē) in Utah and Colorado, encompassing the spectacular river canyons of the Green and Yampa.
Though lesser-known than the fossil beds, the petroglyphs in Dinosaur National Monument are another treasure the monument holds. Due to problems with vandals, many of the sites are not listed on area maps.
The Quarry:
The Dinosaur wall located within the Dinosaur Quarry building in the park consists of a steeply tilted (67°From the horizontal) rock layer which contains hundreds of dinosaur fossils. The enclosing rock has been chipped away to reveal the fossil bones intact for public viewing. In July 2006, the Quarry Visitor Center was closed indefinitely due to structural problems that have plagued the building since 1957 as it was built on unstable clay. The current preferred plan is to rehabilitate the existing Quarry building, destroying the serpentine ramp, administrative, and museum facilities. A new facility to house the visitor center and administrative functions would be constructed elsewhere in the monument. This plan would provide a safe structure while still retaining a portion of the historic Mission 66 era exhibit hall. ...
Echo Park Dam controversy:
U.S. Bureau of Reclamation plans for a ten-dam, billion dollar Colorado River Storage Project began to arouse opposition in the early 1950s when it was announced that one of the proposed dams would be at Echo Park, in the middle of Dinosaur National Monument. The controversy assumed major proportions, dominating conservation politics for years. David Brower, executive director of the Sierra Club, and Howard Zahniser of The Wilderness Society led an unprecedented nationwide campaign to preserve the free-flowing rivers and scenic canyons of the Green and Yampa Rivers. They argued that, if a national monument was not safe from development, how could any wildland be kept intact?
On the other side of the argument were powerful members of Congress from western states, who were committed to the Colorado River Storage Project in order to secure water rights, obtain cheap hydroelectric power and develop reservoirs as tourist destinations. After much debate, Congress settled on a compromise that eliminated Echo Park Dam and authorized the rest of the project. The Colorado River Storage Project Act became law on April 11, 1956. It stated, “that no dam or reservoir constructed under the authorization of the Act shall be within any National Park or Monument.”
Historians view the Echo Park Dam controversy as signaling the start of an era that includes major conservationist political successes such as the Wilderness Act and the Wild and Scenic Rivers Act.
