What year did the park become an
official National Park and why?
Big Bend became an official National Park in
1944. It was done so that an area along the
Rio Grande would be a source of enjoyment
for future generations. The park is rich in
biological and geological diversity. It was also
to protect scenery and protect wildlife.
How was the park formed? (From an
earth science perspective)
The Big Bend was formed from the hard blowing
wind that pushed materials such as gravel,
sand, and clay that soon created sandstone
and shale beds that will stay for years to
come. Also, limestone's are now seen a lot in
the Big Bend.
What Type of Rocks Are Found in
Big Bend?
Some types of rocks that can be found in Big
Bend include sedimentary, igneous, marine
rocks, and ancient volcanoes.
What Special Landforms or
Features Are Inside Big Bend
Some special landforms and features inside Big
Bend are mineralization, faults, folds, and
badlands. Lowlands and canyons can also be
found there due to erosion.
How is the land in your park
currently changing?
Geological forces are shaping Big Bend till this
day. Forms of erosion also continue to create
the park. Landscapes and features are made
up from the organisms in the park.
What environmental issues are
affecting your park?
Pollution is destroying some of Big Bend’s
resources. Also, air quality is sometimes an
issue. Haze is another problem too, because it
affects the airflow. It is most frequent in late
summer and early fall seasons.
How is technology being used to
preserve and maintain your park?
Big Bend National Park uses an Aerosol Sampler which
inhales air 24 hours twice per week. It helps camp
geologists monitor sulfates, nitrates, organic carbon,
and soil. It also has an automated camera system
that takes photos of distant scene at nine AM, twelve
noon, and three PM every day. Their Ozone Monitor
checks for harmful oxygen in the atmosphere
continually and the National Atmospheric Deposition
Program monitors elements of metals and chemicals
that are in the precipitation samples. The last piece
of technology they use is a Particulate Monitor. They
are two machines that determine very small particles
