Mount Rushmore has already changed their plans for the 4th of July celebration from Fireworks to live entertainment because of the infection of their trees by the Mountain Pine Beetle (due to fire danger with the dry dead trees), and today they announced plans to treat the trees surrounding the faces of Mount Rushmore with hopes of slowing the spread of the beetles.
The official Press Release is below, but what it says is that they will be cutting down and removing some infected trees and spraying others with insecticide. While they are doing this they will be closing areas that they are working in...this may affect your rock climbing trip to the Mount Rushmore Area if it happens to overlap with this work.
Mount Rushmore is home to some of the oldest and largest trees in the Black Hills National Forest so I understand their reason in wanting to protect them, but the beetle kill is an act of nature and so I find it rather interesting that the National Park Service would choose to interfere with it though the use of pesticides.
Many of you will notice that the Black Hills are changing and the forest will become more open and in many ways more "natural" due to the Mountain Pine Beetle that is currently at levels that are well within the historic norms. The suppression of fire allowed the forest to get overly thick, and with the drought of recent years combined with many other factors to start up the Mountain Pine Beetle cycle here in the Black Hills and many other forest across the western states. I always find it interesting how mother nature has a way of working things out. We will all experience great new views of the beautiful landscape that surrounds us as the trees fall. Already with the work that Custer State Park and the Forest Service have done...there are rock faces exposed that I have not seen (or Climbed on) even though I've lived here since the mid ninety's.

Mount Rushmore National Memorial News Release
Mount Rushmore Implements Mountain Pine Beetle Action Plan
(Keystone, SD) On Friday, June 4, 2010 Mount Rushmore National
Memorial will begin implementing the Mountain Pine Beetle Assessment and
Action Plan to address the mountain pine beetle (MPB) epidemic that is
occurring in the central Black Hills. The action plan was developed by an
interdisciplinary team earlier this year and outlines steps that would
protect the memorial from wild fire, and would slow, and hopefully mitigate
the spread of the pine beetle, while protecting some of the old growth
forest of the memorial.
The first phase of the plan will begin on Friday and involves
identifying green trees that are infested with the MPB. These trees are
currently hosting the newest generation of pine beetles and have been
killed by the beetles. Pine beetles in green infested trees typically
leave the trees in July and August to find new host trees. With the help
of South Dakota State University and the South Dakota Cooperative Extension
Master Gardeners, Mount Rushmore will be surveying the forest to identify
and mark green infested trees. Once these trees have been identified, they
will be cut down and dried out to remove and kill the immediate pine beetle
population that is in the park. This process will be done every year to
identify any new beetle infestations.
The second phase of the plan will begin Tuesday, June 8 to protect
the large diameter, high value trees within the visitor areas. High value
trees have been identified as trees larger than 10 inches in diameter and
ones that contribute to the forested views of the memorial. If these trees
were gone, visitor views of the memorial would look very different. The
trees will receive a preventative insecticide spray that will ensure the
forested views of the memorial will remain intact.
Mount Rushmore has identified over 700 trees to be sprayed during the
month of June. Carbaryl 4L insecticide spray is the chosen spray for this
project. It has proven success in the Black Hills and has also been used
in Rocky Mountain National Park to combat the MPB. Trees will be sprayed
on their trunks by spray units on the ground. While the spray is being
applied to the trees, many visitor areas may be closed to the public.
Actions to insure the health and safety of park visitors and staff include
park closures to keep sprayed areas secure. Areas that have been sprayed
will be closed to visitors and staff for approximately 3-5 hours while the
carbaryl dries on the trees. Once the spray is dry, the area is safe to
reenter. Signs will be posted near the sprayed areas to identify trees
that have been sprayed. Spraying is scheduled to occur in the early
morning, with areas closed to the public until 12 or 1 pm. Areas will be
sprayed in sections and include trees along the Presidential Trail, around
the historic Sculptor’s Studio and along the roadways.
The memorial hopes that these proactive and preventative measures
will protect the park’s forest from the worst damage caused by the current
MPB epidemic. The most active area of MPB infestation and highest
concentration of tree mortality is in close proximity to the memorial and
the oncoming infestation has recently been observed within the park as
well. The current outbreak appears to be larger and more widespread than
historically typical. Mount Rushmore’s MPB Assessment and Action Plan was
developed to address the current epidemic and identify actions that will
return the forest to a more historic and sustainable condition that can
naturally protect itself against future pine beetle infestations. The
final action plan is available on the NPS Park Planning website,
