Introduc on
Overview Map
Introduc on
City of Rocks Na onal Reserve has long been an oddity and
wonder, especially for passing emigrants on the California Trail
(1843‐1882).
Many of these emigrants wrote entries in their journals naming
the rock features as they traveled through the valley.
“…Pyramid Circle and the hills which encircle it, were the most
beau ful and wonderful white rocks that we ever saw. This is
known as the City of Rocks…” –Helen Carpenter 1857
Many of the granite forma ons were named by emigrants on the
trail, local residents, and rock climbers. Can you see what they
saw? Use your imagina on; you might come up with a be er
name for the rocks.

Steinfells Dome and
Jacksons Thumb
Steinfells Dome and Jacksons
Thumb are favorite mul ‐pitch
climbs. The dome is named a er the
legendary Steinfell Climbing Club of
Utah; many routes were climbed
during the late 1960’s.
Jacksons Thumb is named a er the
late Ned Jackson, Superintendent
from 1990 to 2001.
6
Stripe Rock
Stripe Rock has become a popular three‐pitch climbing
des na on since the popular route “Cruel Shoes” was
established by Kevin Pogue.
The stripe running down this
forma on resulted as rock
cooled slower than the
surrounding granite, forming
an aplite dike.
7
Lost Arrow Spire
Lost Arrow Spire—City of Rocks
Lost Arrow Spire—Yosemite
Rock climbers in the 1960’s no ced the uncanny
resemblance between the City’s Lost Arrow and the iconic
spire in Yosemite Valley of the same name. The re‐use of
names of several features represents the deep‐rooted
connec on that early climbers had to Yosemite.
8
Box Top
The box on top of this granite monolith resulted from the
weathering of horizontal and ver cal joints. Look for this
feature on the west side of the Circle Creek Basin.
See Map on page 20 ‐21.
9
Clam Shell
Once you recognize the “clam shell” in this granite dome,
it will catch your eye on every visit. Most see it as they
drive through the Reserve; however, very few venture out
to experience the Clam Shell up close.
10
Tracy Homestead
The stone house was home to many early se lers beginning
with William E. Tracy circa 1901. W.E.T. was placed on a stone
on the south side outside upstairs bedroom window.
John H. Hull occupied the house circa 1909 and remodeled the
east bedroom on the main floor, adding the large window and
capstone with the inscrip on MAR 29 1909 J.H.H.
The house was empty for many years and then burned in 1967.
Please respect private property within the Reserve.
11
Camp Rock
Camp Rock was a favorite res ng place for traveling
emigrants. Some wrote their names in axle grease on the
rock face; now over 160 years later, we can see those names
and wonder what it was like for them as they traveled
through the “Silent City.”
Take a moment and walk around the rock. You will see
hundreds of inscrip ons and dates ranging from 1843—1882.

Chicken Rock
This granite forma on is an excellent example of spires, joints
and weathering.
Some call this rock Sco y Dog others have called it Oriental
Castle. What do you see?
There are emigrant signatures on this forma on as well. Please
do not climb or scramble on forma ons with signatures.
13
Monkey‐Face Rock
Be crea ve; can you spot the monkey’s face?
What intriguing shapes and figures can you find on your visit to
City of Rocks? Write them down, take a picture of them, and
share them at h ps://www.facebook.comCityOfRocksNa onalReserve
14
Cinderella Slipper
Is this Cinderella’s lost slipper? This oversized shoe is
featured on the same forma on as Monkey‐Face.
The granite slipper measures five feet wide and 25 feet
long.
15
Kaisers Helmet
Let your imagina on wander. Visualize this spike‐like
protuberance (pickelhaube) on the summit as a spiked helmet
worn by German soldiers in WWI. Now do you see why it is
named Kaisers Helmet?
16
Treasure Rock
With tales of stolen gold and buried treasure, this forma on is
shrouded in mystery and lore. Do you believe the story of
buried treasure? A roadside a rac on, Treasure Rock sees
many curious visitors each year.
This legend is plausible. Although versions of the robbery
differ, most agree that the Kelton stage was robbed circa
1878 in gold bullion bound for a U.S. military camp in Boise.
One bandit (in some accounts, two) was killed in the
confronta on. The second was captured days later a er
reportedly burying the treasure at the base of what soon
become know as Treasure Rock.
17
Circle Creek Basin
You will o en see ca le grazing on the lush meadows of Circle
Creek Basin during the spring and summer months. The
emigrants nooned and camped on the edge of the Basin.

Devils Bedstead
Perched on a hill looms a feature with an ominous name—the
Devils Bedstead. Can you see the headboard on the le and
the footer on the right? Only the devil would sleep on a
ma ress of uneven granite!
Tigway is precariously
perched. Is this the
next rock to fall in City
of Rocks?

Register Rock
Register Rock conveys many shapes, depending on the viewing
angle. Many see a sleeping camel, others see a turtle or the profile
of Andy Gump.
Take a moment to view the signatures wri en in axle grease.
Emigrants, like A. Freeman and D. Tickner, stopped here on June
12, 1850 and “registered” their names.

22
Elephant Rock
This majes c dome resembles an elephant marching off into
the sunset. Elephant Rock is one of the more easily accessible
and popular climbing forma ons.
23
Window Arch
Window Arch is one of the most frequently visited
features in the Reserve, popular for group photos. The
arch is located 300 feet north of campsite 37 .
24
Historic Corral
This early 20th Century corral, part of the Durfee Homestead,
fell into disrepair un l restored by BS Troop 18 in 2013. The
corral is nestled against the rock and is difficult to see from the
road. Take a short walk south from Elephant Rock to visit the
corral.
25
Bath Rock
Snow and rainwater fill a large depression or panhole on top of
Bath Rock, giving rise to the name. Many visitors climb the
rela vely easy southwest face for a magnificent view of City of
Rocks.
In 1939 and 1940 the Bathtub Rock Bathing Beauty Parade was
held here.
26
Creekside Towers
Creekside Towers Trail
winds along the base of this
imposing feature. The trail’s
gentle grade is suitable for
families with children. Snow
mel ng in the spring creates
a small cascading waterfall
adjacent to the trail.
27
Morning Glory Spire
Morning Glory Spire (a.k.a. The Incisor) stands tall above the
Inner City. The east face is glorious in the morning. The so rays
of the rising sun bathe the spire in light.
28
Anteater
This eye‐catching dome is the home of the classic
“Scream Cheese” climbing route. This rock is
frequented by climbers and is accessible from
Creekside Towers Trail or Parking Lot Trailhead.
29
Window Rock
Salt, wind, and water
conspire to carve a window.
Chemical and mechanical
erosion con nue to enlarge
this feature.
For more informa on about
erosive processes pick up
the Geological Interpre ve
Trail booklet at the Visitor
Center.
30
Parking lot Rock
The naming of this forma on could have gone something like this:
Climber 1 ‐ “I just did this amazing climb today!”
Climber 2 ‐ “Where was it, I’ll check it out tomorrow…”
Climber 1 ‐ “It’s over on that rock by the parking lot.”
Climber 2 ‐ “Oh, Parking lot Rock…”
31
King on the Throne
This feature is best seen when driving downhill from Bread
Loaves. O en the history of named forma ons is lost in me. Is
King on the Throne named a er a feature that resembles a
stone king or is it named a er Ted King, a local rancher who
once used a corral just south of this rock?
32
Owl Rock
Great Horned Owls o en choose this forma on on
which to nest. Rock climbers in the 1980’s, a er
mul ple frightening encounters with nes ng Owls,
named this feature.
33
Eric Wood
Si ng prominently above City of Rocks, this
forma on was named a er a real person, Eric Wood.
His friend and climber, Jay Goodwin dubiously
honored Eric a er recognizing his profile in the north
end of the forma on.
34
Bread Loaves
Bread loaves needs no introduc on when viewed
from the west. How many slices can you see?
The greatest thing since sliced bread—climbing
on Bread Loaves has always been popular.
35
Twin Sisters
Twin Sisters majes cally rises 750 feet above the basin floor. The
granite pinnacles were a landmark on the California Trail.
Addison Pra an officer with the Mormon Ba alion returning from
California named the forma on on September 15, 1848. Geologists
marvel at the forma on of the deep crustal granites of the Green
Creek Complex and Almo Pluton.
For more

the Twin Sisters see

Pinnacle Pass
Pioneers moving along the California trail traveled through Pinnacle
Pass. The ruts and the swales can s ll be seen today.
See the California Na onal Historic
Trail Guide for more details.
Access to Pinnacle Pass is available
through guided ranger tours arranged
at the Visitor Center. Please respect
