Armchair Photography Guide to Mount Rainier – Part 1: Sunrise

Foggy Sunrise At Tipsoo Lake - Closer

I just realized after posting Part 2 of this Armchair Photography Guide, that I neglected to ever post Part 1!  So, click on the photo above to be taken to Part 1, published in the National Parks Traveler back on September 12, 2017.

Anticline Overlook, Utah

Anticline Overlook Map

I’ve been remiss about “feeding the beast” and making regular weekly contributions to my site (and don’t even ask me about the reading catch-up I need to do with my favorite blogs).  It’s the holiday season and I’ve been involved with other  photo business, which has kept me occupied with non-blog issues.  I now have enough vacation to take every Friday off for the remainder of the year, so hopefully these 3-day weekends will give me more time to catch up on  the blogosphere.

As previously promised, this article is not about any camera/lens comparisons.  Instead, I want to tell you about  an interesting, somewhat out-of-the-way viewing area I visited en route to Moab, Utah.

During the planning stages of my Mesa Verde NP / Arches NP trip this past August 2012, I was looking at Google Maps and noticed a side road off of Hwy 191 (the road to Moab), with the title “Needles / Anticline Overlooks”.  An anticline!  Yeah!  I like geology.  I have a couple of degrees in geology, as a matter of fact.  I’d LOVE to see an anticline.  So I added that to my itinerary.

The route to Anticline Overlook is a 31-mile, 2-lane (more or less) road – 16 miles of which is on gravel .  It’s a well-tended gravel so I didn’t worry too much about driving the rental car along the road (I should have taken a photo of how dusty the car looked upon my return to the main highway).

Where the paved portion ends and the gravel begins, you have the choice of turning left to the Needles Overlook or continuing on to Anticline Overlook.   I decided to save Needles for another time.

This prong horn antelope was standing in the middle of the road, but by the time I stopped the car and grabbed the camera, it had sauntered off, totally ignoring me and my pleas to look my way for a portrait shot.

The ultimate destination ends in a loop, with plenty of room for parking and a nice little pit toilet.  A short trail leads to the overlook, with views  northwest, north, and northeast.  The view is expansive and the air fresh and clear.

If you are traveling Hwy 191 Utah –  north to or south from Moab – and your vehicle  can handle the gravel, this is a neat side trip for a great view of Utah’s canyon lands and geology.

Utah Geology Rocks!

B5A6838_Fault and Runner

I have a couple of degrees in geology, and although I am not a geologist by profession (I graduated with my MS degree at the wrong time), I am still totally enthralled by geology and geologic processes.

Utah is an earth sciences treasure trove. The few photos here that I captured along Hwy 191, at Anticline Overlook, and in Arches National Park are just the tip of the geologic iceberg.

The factoids in this post were taken from the internet as well as three different publications:

Roadside Geology of Utah, by Halka Chronic

Canyonlands Country, by Donald L. Bars

Geology Unfolded, by Thomas H. Morris et al

Travel with me as I depart Monticello, UT and head toward Arches National Park, along Hwy 191.

B5A6517-Church Rock

C2C7643_Church Rock

Sitting by itself, all rounded and monumental, Church Rock, along Hwy 191 heading north from Monticello to Moab, is an erosional remnant (a bedrock formation that remains after extensive erosion).

C2C7664_Cane Creek Anticline

Anticline Overlook, some 32 miles west-northwest of Hwy 191 along a scenic byway (15 miles of which are well-tended gravel), is so named for the curved, uplifted shape of the Cane Creek Anticline visible across the Colorado river (the left portion of this photo).

C2C7696_Kane Creek Canyon

Anticline Overlook sits upon a promontory with views of the Colorado River, Dead Horse Point State Park, and Kane Creek Canyon, pictured here (yeah, I don’t get the difference in spellings either, but that’s how they appear on the internet).

C2C7720_Wilson Arch

One of the first arches one sees along Hwy 191 toward Moab is Wilson Arch, which  formed from massive sandstone eroded on both sides by water and wind into a “fin”.  Further erosion on both sides of the fin along joints in the rock formed  an alcove, then a cave, then ultimately the arch seen here.

B5A6983_Afternoon At La Sal Mountains Viewpoint

Subsurface magma intrusions squeezed in between rock layers to form dome-shaped igneous  “laccoliths”. The overlying sediments were eroded away, exposing these laccoliths to become what we call the La Sal Mountains.

B5A6689_Moab Fault

B5A6696_Moab Fault Sign

I couldn’t quite get the big picture and it took me a bit of puzzling to figure out exactly where the Moab Fault is located (I mean, relative to me.  I know the Moab fault is located near Moab, UT).  After re-reading the sign at the Moab Fault overlook, right inside the park, I finally got it.  Looking at the photo of the area across the highway from where I stood (I was at the “you are here” part of the sign) is the upthrown fault block, while the area on my side of the highway is the downthrown fault block.  The fracture line is basically parallel to the highway. The fault displacement (how much it’s gone down/up) is about 2500 feet!

B5A6773_Geology

Arches in the making.  With continued erosion via water and wind, those holes you see now will eventually become arches….but not in my lifetime….or your lifetime…..or your kids’ lifetimes…..or….well, you get it.

C2C7799_Entrada SS and Dewey Bridge Member

C2C7802_A Closer Look CROP

Those squiggly rock layers along the bottom of this big sandstone structure are collectively called the Dewey Bridge Member.  A “member” is a distinctive rock within a formation (a formation is a distinctive, mappable rock unit).

B5A6787_Balancing Act

The Dewey Bridge Member erodes far more easily than the sandstones sitting atop it.  This is called differential erosion.  The pinnacle known as Balanced Rock was formed because of differential erosion.

B5A6881_Dwery Bridge Member and Pinnacle TEXT

Another example of a pinnacle, the Dewey Bridge Member, and differential erosion.

B5A6894_Salt Valley Explanation

Salt Valley does indeed consist of salt deposits. Hundreds of millions of years ago, this entire area was a sea. Layers of salt thousands of feet thick were deposited right here. Salt domes were formed, creating uplift in the land. Huge cracks occurred in the uplifted layers, water poured in, salt leached out leaving empty spaces, and collapse ensued, creating this valley. OK, it’s a simplistic explanation, but I’m writing this for mostly non-geologists and this is indeed what happened.

B5A6896-2_Salt Valley and Devils Garden

B5A6889_Salt Valley and Devils Garden

The above photos are looking over Salt Valley toward Devils Garden (consisting of a bunch of those “fins” I described earlier).

B5A7026_Salt Valley

B5A7035_Salt Valley and La Sals

These two photos are looking the other way, across Salt Valley toward the La Sal Mountains and the Windows Section of the park.

B5A6908_Erosion

Here’s a nice example of weathering by water (frost and rain) and erosion.

C2C8446_Landscape Arch

All arches struggle with the pull of gravity, and Landscape Arch is no exception. This was proved back in 1991 when a 60-foot slab of this arch fell to the ground (that’s 180 tons of rock debris, according to the sign near this arch). There is no longer a path leading to a view beneath the arch.  It’s all fenced off now, although I’m pretty sure some photographers still risk it to get that perfect image.  The thing is, nobody can predict there won’t be more slabs of rock sloughing off from this arch unexpectedly.  Who knows? Maybe in my lifetime, that arch will indeed totally collapse.

B5A7290_Geologic Panorama CROP Text

Heading out of Moab, UT on toward Grand Junction, CO, I stopped to photograph this view. I later discovered this very same scene had been published in one of the books referenced at the beginning of this post: a real-life stratigraphic column of the Jurassic-age (140 – 200 million years ago) rock found within Arches National Park.  I just originally photographed it because I thought it was really cool, with all those differing layers of sandstone….and I figured it would make a great addition to a geology blog post I was thinking of writing Winking smile

These few photos show just a little bit of the wonderful geology found in Utah.  You don’t have to be a geologist or a geology student to totally understand the processes that created all of these wonders.  All you really need is an observant eye and an appreciation of the geologic results.
