JoshuaTree NP Geology Tour
JoshuaTree NP Geology Tour text
GPS 34.00094 -116.08540, #1-Why A Valley
Queen Valley, a mountain-rimmed valley at an elevation of 4,450 feet is one of two types of valleys along the geology tour. The Queen Valley are
formed by a difference in the rate of erosion between the rock material on the valley floor and the rock making up the surrounding mountains.
The valley material disintegrates more rapidly than the mountain rock, and forms a low-lying plain, or valley. The rocky mountain sides are more
resistant to erosional forces, such as wind and water, and maintain their height as the valley becomes deeper. Pleasant Valley, seen later in the
tour, is the result of faulting uplift and subsidence, another type of valley carving.

A Raindrop Divides
This knoll is the north-south drainage divide for the park. Typically, one would think a divide would occur on the crest of a mountain range.
However, in this case water drains either northwest to Quail Springs Wash, or southeast into Pinto Basin through the Fried Liver Wash,
depending on which side of the knoll it falls. The Queen Valley actually is shaped like a broad dome if viewed from a distance.

GPS 33.96603 -116.07893, #3-Nature Gutter
Nature's Gutter
This is a dry intermittant stream channel, more commonly known as a wash. Intense rainfall can produce flash flooding. Mineral grains, loosened
from rocks by weathering, are moved further down the wash by flooding. It may take a number of storms before the grain is finally deposited in an
alluvial fan or dry lake.
The soil here contains more moisture. This allows some plants to grow here more readily than in the drier soil away from the wash.
- NEXT
GPS 33.96167 -116.07815, #4-Old Erosional Level
Old Erosional Level
Many of the monzogranite boulders here bear a distinct groove about seven feet above the ground level. The sides of the boulders are generally
steeper above this line than below it. This line indicates where a stable soil existed, protecting the bottom of the boulder from erosional forces
during a wetter climate. Afterwards, during a drier climate, the soil surface eroded more rapidly. During this period there has not been nearly as
much time for the lower surfaces of the boulder to weather, so the surfaces below the old soil level are not so steep.
- NEXT
GPS 33.95514 -116.07798, #5-Rock Piles
Rock Piles
The monzogranite forming these rock piles was once a molten mass which was forced upward, or intruded, into an older layer of Pinto Gneiss.
The molten mass (magma), cooled about 15 miles below the surface and crystalized to form solid rock. The overlying gneiss has been stripped
away by erosion over the years, exposing the monzogranite outcrops. Within the monzogranite, areas with wider spaced joint cracks are more
resistant to erosion, and weather more slowly than the cracks that are closer together. This type of wear results in the high rock piles called
inselbergs. In some piles the joint crack systems are well defined and obvious, while in other piles smaller boulders have fallen into disordered
piles obscuring the underlying joint pattern.

GPS 33.94651 -116.07781, #6-Rock Sculpture
Rock Sculpture
The White Tank monzogranite found at Joshua Tree National Park displays probably the most extensive rounded rock masses than any place in
the world. Large bodies of monzogranite have sets of cracks, called joints, that intersect at roughly right angles to each other. Nearly vertical
cracks probably occured when the rock cooled and contracted; faulting may have also contributed. As erosion removed the overlying rock,
horizontal cracks were made when the rock mass expanded upward.
Jointing produces blocks of more or less cube-shaped rock. While the monzogranite was below the surface water containing carbon dioxide
seeped down through the joint. This action wore away at the cracks little by little, breaking off mineral grains from the joints. This type of erosion is
more effective at the edges and corners, and over a long period of time, changed the rock shape from cubical to spherical.
- NEXT
GPS 33.93979 -116.07802, #7-Malapai Hill
Malapai Hill
The twin peaks of Malapai Hill rise about 400 feet above the valley floor. The black basalt that composes the hill is harder and more resistant to
weathering than monzogranite. As the basalt intruded the monzogranite, it may or may not have reached the surface. If it did reach the surface,
any cinder cone of lava flow it may have produced has long since eroded and disappeared. This intrusion may have happened at two or three
million years ago; which is quite recent when compared to the age of monzogranite at 85 million years, and gneiss at 1.7 billion years.
- NEXT
GPS 33.93510 -116.07708, #8-Alluvial Fans and Bajadas
Alluvial Fans and Bajadas
Alluvial fans are made up of sand, gravel and rock which has fallen and was washed down from rock at higher elevations. Larger, heavier rocks
are deposited at higher elevations, and smaller pieces carried further down and deposited in a fan shape. A bajada is created when alluvial fans
merge into a single slope. Eventually, a bajada may become buried deeply underground and consolidate into sedimentary rock, which, could be
uplifted by faulting and become mountains in the distant future.
- NEXT
GPS 33.92948 -116.07660, #9-Squaw Tank
Squaw Tank is an excellent place to observe interesting geological features as well as some of the ways man has made use of the environment.
The White Tank monzogranite originally formed 15 to 20 miles below the surface of the earth as magma. This magma cooled slowly, which
allowed for large crystals to form
Dikes/Intrusions
The light-colored bands of rock cutting across the monzogranite were formed when molten magma pushed through joints in the rock. Being of a
harder material (aplite or pegmatite), dikes as they are called, are more resistant to erosion and weathering, and tend to protrude above the
bedrock as low walls.
Cavernous weathering produces pits and hollows on rock surfaces. Water catches in irregularities and begins a chemical breakdown of the rock
into clay. This clay holds more moisture and produces an even larger amount of breakdown in the rock. As the pit becomes larger it can produce
shade, cooling the retained water and occasionally freezing, as well as fostering lichen growth. These processes promote both the chemical and
mechanical breakdown of the rock.
Use by Man
Archaeological investigations show that this area has been used by semi-nomadic Native Americans have used this area for roughly 1,000
years. Stone mortars in the bedrock can be found which were used for grinding seeds. The caverned openings in the rock may have been used
for fire and shelter. Water pooled in natural tanks were an attraction for Native Americans who camped in the area, and later on, Cattlemen, who
built a concrete dam to collect water from rains.

GPS 33.92665 -116.07527, #10-Pleasant Valley
Pleasant Valley
The Blue Cut fault is an earthquake fault that runs for about 50 miles through the Little San Bernardino Mountains, under Pleasant Valley, and into
the Pinto Basin. It is named after the Blue Grandiorite exposed on the mountains at the southwestern edge of Pleasant Valley, the main branch of
the fault.
The Hexie Mountains were pushed up from the northern branch of the fault to form the steep, straight southern edge of this range of gneiss. The
land to the south, between the two branches, dropped down and subsided to create the depression that became the Pleasant Valley.
Patina
The dark rocks at the end of the Hexie range are coated with a patina. Known as "desert varnish," this coating is composed of clay, iron and
manganese oxides. Accumulation of this patina happens at an incredibly slow rate over thousands of years. The layers of patina can be read by
scientists investigating climatic changes over these thousands of years.
- NEXT
GPS 33.92479 -116.06290, #11-Debris Flows
Debris Flows
Occuring at the mouth of this steep canyon in the Hexie Mountains, are irregular mounds of gneiss debris lacking a coating of patina. This lack of
patina indicates more recent flows, not yet resulting in a debris fan. During heavy rains, the debris becomes saturated and oozes toward lower
ground. As materials from higher up in the canyon wear down, a debris fan may develop, then possibly, over a long period of time an alluvial fan.
- NEXT
GPS 33.92345 -116.05415, #12-Mines in the Hexie Mountains
Mines in the Hexie Mountains
The Hexie Mountains slopes are riddled with mine tunnels and shafts dug by miners in search of gold and other precious metals. Extensive
mining activity took place in the late 1800's and early 1900's, however, very few of the mines produced ore of a high enough grade to be
profitable.
Metals of economic importance, such as gold, silver copper and lead are belived to be deposited when intruded magma cools and crystalizes
along with gasses and liquid solutions rise. The Blue Cut fault zone was believed to have created pathways in which solutions reacted with
metal-bearing quartz veins.
- NEXT
GPS 33.92257 -116.05416, #13- Pleasant Valley Dry Lake
Pleasant Valley Dry Lake
The upheaval of the Hexie Mountains with subsidence of the area north of the southern fault line, created a low area in which a periodic lake
existed during a wetter climate. Sediments made of clays and sand were carried from nearby slopes and alluvial fans to be deposited at depths
of several hundred feet. As time went on, and the lakebed rose, the slope extending from the canyons and alluvial deposits lessened. With this,
finer silts and dissolved salts drying began to level the bottom of the valley creating what we see now as a dry lake, or playa. Although salt
deposits here are not as obvious as in other desert dry lakes (where extremely few, or, no plants grow), evidence of the salt content can be seen
in the presence of salt-tolerant plants species. Interestingly, after heavy rains, many dry lakes become temporary "wet" lakes.
- NEXT
GPS 33.90156 -116.08481, #14-Pinto Gneiss
Pinto Gneiss
The banded and folded Pinto gneiss, approximately 1.7 billion years old, is most likely the oldest type of rock in the park. Gneiss, a metamorphic
rock, has undergone change in mineral composition, grain size and orientation due to increases in pressure, heat and chemical activity. Gneiss,
prior to its change, was a sedimentary rock. With directed pressure, mineral grains segregate and band together; this alternate banding of light
and dark minerals is what defines a gneiss.
Pinto Gneiss
Lichens
Brightly colored splotches found on the gneiss are a primitive form of plant life called lichens. Lichens are a mutually beneficial composite of fungi
and algae. The various colors indicate different species. Some species form a weak carbonic acid, the primary agent in the chemical breakdown
of rock into soil.

Pinyon Well Junction
This is the alluvial fan at the upper end of the bajada at Alluvial Fans and Bajadas described previously. Further up this canyon is the site of
Pinyon Well, a source of water used for processing ore and watering cattle.

Panoramic View
In this tour of the Queen and Pleasant Valley's, we've seen rock records dating back nearly two billion years. Mountain building over at least two
separate and distinct periods, examples of different type of erosion and indication of how, and why man survived in the desert. With the active
San Andreas fault to the south, and minor faults such as the Blue Cut, the scenery here is dynamic and subject to change -- Exactly how it will
change though, can only be left to speculation.

million years ago; which is quite recent when compared to the age of monzogranite at 85 million years, and gneiss at 1.7 billion years.

Alluvial Fans and Bajadas
Alluvial fans are made up of sand, gravel and rock which has fallen and was washed down from rock at higher elevations. Larger, heavier rocks
are deposited at higher elevations, and smaller pieces carried further down and deposited in a fan shape. A bajada is created when alluvial fans
merge into a single slope. Eventually, a bajada may become buried deeply underground and consolidate into sedimentary rock, which, could be
uplifted by faulting and become mountains in the distant future.

GPS 33.92948 -116.07660, #9-Squaw Tank
Squaw Tank is an excellent place to observe interesting geological features as well as some of the ways man has made use of the environment.
The White Tank monzogranite originally formed 15 to 20 miles below the surface of the earth as magma. This magma cooled slowly, which
allowed for large crystals to form
Dikes/Intrusions
The light-colored bands of rock cutting across the monzogranite were formed when molten magma pushed through joints in the rock. Being of a
harder material (aplite or pegmatite), dikes as they are called, are more resistant to erosion and weathering, and tend to protrude above the
bedrock as low walls.
Cavernous weathering produces pits and hollows on rock surfaces. Water catches in irregularities and begins a chemical breakdown of the rock
into clay. This clay holds more moisture and produces an even larger amount of breakdown in the rock. As the pit becomes larger it can produce
shade, cooling the retained water and occasionally freezing, as well as fostering lichen growth. These processes promote both the chemical and
mechanical breakdown of the rock.
Use by Man
Archaeological investigations show that this area has been used by semi-nomadic Native Americans have used this area for roughly 1,000
years. Stone mortars in the bedrock can be found which were used for grinding seeds. The caverned openings in the rock may have been used
for fire and shelter. Water pooled in natural tanks were an attraction for Native Americans who camped in the area, and later on, Cattlemen, who
built a concrete dam to collect water from rains.

Pleasant Valley
The Blue Cut fault is an earthquake fault that runs for about 50 miles through the Little San Bernardino Mountains, under Pleasant Valley, and into
the Pinto Basin. It is named after the Blue Grandiorite exposed on the mountains at the southwestern edge of Pleasant Valley, the main branch of
the fault.
The Hexie Mountains were pushed up from the northern branch of the fault to form the steep, straight southern edge of this range of gneiss. The
land to the south, between the two branches, dropped down and subsided to create the depression that became the Pleasant Valley.
Patina
The dark rocks at the end of the Hexie range are coated with a patina. Known as "desert varnish," this coating is composed of clay, iron and
manganese oxides. Accumulation of this patina happens at an incredibly slow rate over thousands of years. The layers of patina can be read by
scientists investigating climatic changes over these thousands of years.

GPS 33.92479 -116.06290, #11-Debris Flows
Debris Flows
Occuring at the mouth of this steep canyon in the Hexie Mountains, are irregular mounds of gneiss debris lacking a coating of patina. This lack of
patina indicates more recent flows, not yet resulting in a debris fan. During heavy rains, the debris becomes saturated and oozes toward lower
ground. As materials from higher up in the canyon wear down, a debris fan may develop, then possibly, over a long period of time an alluvial fan.

Mines in the Hexie Mountains
The Hexie Mountains slopes are riddled with mine tunnels and shafts dug by miners in search of gold and other precious metals. Extensive
mining activity took place in the late 1800's and early 1900's, however, very few of the mines produced ore of a high enough grade to be
profitable.
Metals of economic importance, such as gold, silver copper and lead are belived to be deposited when intruded magma cools and crystalizes
along with gasses and liquid solutions rise. The Blue Cut fault zone was believed to have created pathways in which solutions reacted with
metal-bearing quartz veins.

GPS 33.92257 -116.05416, #13- Pleasant Valley Dry Lake
Pleasant Valley Dry Lake
The upheaval of the Hexie Mountains with subsidence of the area north of the southern fault line, created a low area in which a periodic lake
existed during a wetter climate. Sediments made of clays and sand were carried from nearby slopes and alluvial fans to be deposited at depths
of several hundred feet. As time went on, and the lakebed rose, the slope extending from the canyons and alluvial deposits lessened. With this,
finer silts and dissolved salts drying began to level the bottom of the valley creating what we see now as a dry lake, or playa. Although salt
deposits here are not as obvious as in other desert dry lakes (where extremely few, or, no plants grow), evidence of the salt content can be seen
in the presence of salt-tolerant plants species. Interestingly, after heavy rains, many dry lakes become temporary "wet" lakes.

GPS 33.90156 -116.08481, #14-Pinto Gneiss
Pinto Gneiss
The banded and folded Pinto gneiss, approximately 1.7 billion years old, is most likely the oldest type of rock in the park. Gneiss, a metamorphic
rock, has undergone change in mineral composition, grain size and orientation due to increases in pressure, heat and chemical activity. Gneiss,
prior to its change, was a sedimentary rock. With directed pressure, mineral grains segregate and band together; this alternate banding of light
and dark minerals is what defines a gneiss.
Pinto Gneiss
Lichens
Brightly colored splotches found on the gneiss are a primitive form of plant life called lichens. Lichens are a mutually beneficial composite of fungi
and algae. The various colors indicate different species. Some species form a weak carbonic acid, the primary agent in the chemical breakdown
of rock into soil.

This is the alluvial fan at the upper end of the bajada at Alluvial Fans and Bajadas described previously. Further up this canyon is the site of
Pinyon Well, a source of water used for processing ore and watering cattle.

Panoramic View
In this tour of the Queen and Pleasant Valley's, we've seen rock records dating back nearly two billion years. Mountain building over at least two
separate and distinct periods, examples of different type of erosion and indication of how, and why man survived in the desert. With the active
San Andreas fault to the south, and minor faults such as the Blue Cut, the scenery here is dynamic and subject to change -- Exactly how it will
change though, can only be left to speculation.

A Note From 33 :
How to setup Google Earths datum
In Google earth goto tools- options- 3D view - Show Lat/Long and set it to degrees only
all my GPS Garmin and Lowrance units are set to degrees examples of what the different datum looks like
Degrees = 36.238349 -118.186862 Always use the minus sign first in longitude -118.186862 in the Fly to line because you are west of zero
longitude, if you are east of zero longitude leave it out.
Degree/Minutes = 36º14.300' 118º11.212'
Degree/Minutes/Sec = 36º14'18.0" 118º11'12.7"
All my coordinates on this forum are in degrees datum format.
Google Maps uses a different datum all together
Hope this helps
