What year did Arches National Park become an
official National Park and why?
The Double Arch

• Arches National Park used to be a National
  Monument before it became a National Park. It
  became a National Monument April 12, 1929. Arches
  National Monument became a National Park on
  November 12, 1971. Arches National Monument was
  created by an Act of Congress to protect the
  sandstone formations (arches, spires, balanced
  rocks, etc). The Act of Congress thought it would
  be even better for the sandstone formations if
  Arches was a National Park so Arches National
  Monument was changed to a national park.

How was Arches National Park formed?

• Tens of thousands of years ago, wind carried
  small particles that weathered and eroded the
  sandstone and other rocks. The wind carried the
  particles at just the right level for the
  particles to cement together and carve out arches
  and other sandstone formations. Myths say that
  the arches could be ancient cities built by
  giants thousands of years ago. Because of
  erosions that might have taken place, the ancient
  cities do not look much like cities anymore.

What types of rocks can be found inside Arches
National Park?
A Sandstone Rock

• Arches was all sandstone before it became a
  national park. It still lies today on what we
  call Arches National Park. Arches National Park
  is famous for its special sandstone formations.
  But what exactly is sandstone? Its a sedimentary
  rock that looks very much like sand. You may be
  wondering, What other rocks are found in Arches
  National Park? Everything in Arches National
  Park is made of sandstone (literally, everything).

What special landforms or features are inside
Arches National Park?
The Dark Angel

• Arches National Park has a very wide variety
  of different landforms and features. Some special
  features include the Delicate Arch, the Skyline
  Arch, the Double Arch, the Landscape Arch, the
  Wall Arch, and the Double O Arch. Some of Arches
  National Parks more unique features are the
  Balanced Rock, the Courthouse Towers, the
  Petrified Dunes, the Devils Garden, the Fiery
  Furnace, and the Dark Angel. All of these
  landforms are special and different than all the
  others. For instance, the Dark Angel, (shown at
  the right), is simply a tower of sandstone while
  the Double Arch is actually two arches put
  together into one beautiful structure.
• Note Many of these landforms are shown sometime
  throughout this PowerPoint.

How is the land inside Arches National Park
currently changing?

The View from Inside an Arch

• Arches National park has changed massively
  in the past and is continuing to change today.
  Scientists expect many more arches to form in the
  future, while at the same time, many arches and
  landforms are collapsing due to weathering and
  erosion. Through deposition, more thick layers of
  rock are slowly being deposited on top of famous
  landforms The beautiful scenery today could be
  gone millions of years in the future (gone
  meaning covered by layers of rock)! As well as
  most other national parks, Arches National Park
  has hundreds of growing and dying plants
  scattered around. I really wonder how these
  plants and landforms will change and develop in
  time.

What environmental issues are affecting Arches
National Park?

• Arches National Park is currently in very
  good condition, but even so, there are still many
  environmental issues affecting the park. Arches
  National Park used to be beautiful under the
  night sky, but now it is filled with light
  pollution ruining the beauty. As you might have
  guessed, it is very windy at Arches National Park
  and there are air pollutants that get carried in
  with the wind and kill natures plants. In
  addition, Arches is covered with cryptobiotic
  crust that can be killed just by someone stepping
  on it, so stay on the trail and help the
  environment!

How is technology used to help preserve and
maintain Arches National Park?

• Technology is a huge part of so many
  national parks Arches National Park probably
  wouldnt even be here right now if it werent for
  technology. First of all, Arches is full of
  hiking trails and maps so visitors wont get lost
  without all these trails, people wouldnt know
  where to go and they might damage the ground by
  stepping in the wrong place. In addition, park
  rangers measure all the landforms here and take
  tests using technology. They check to see if any
  landform is close to collapsing and make sure no
  one goes near those landforms. Arches National
  Park always stays safe for visitors, with the
  help of technology, of course!
