Clingmans Dome Tower Rehabilitation Project Begins Today

Great Smoky Mountains National Park officials announced that the Clingmans Dome Observation Tower will be closed beginning today, August 23rd, through the remainder of the 2017 season to complete rehabilitation work thanks to funding received from a Partners in Preservation (PIP) grant. The $250,000 grant was awarded last summer to the Friends of the Smokies on behalf of the park after being one of the top nine, most voted for parks in the Partners in Preservation: National Parks Campaign in 2016.

Straddling the North Carolina and Tennessee state line at 6,643 feet, the tower is a prominent landmark and destination as the highest point in the park. The rehabilitation work will consist of repairing the worst deteriorated areas on the concrete columns and walls, stabilizing support walls at the base of the ramp, and repointing some stone masonry. To accomplish this work in a timely manner and for the safety of our visitors the tower will be closed for the duration of the project.

While visitors will not be able to climb the tower for views out over the surrounding tree tops, the Clingmans Dome parking overlook will be open and offers outstanding mountain top views. The visitor contact station and store, the trail to the tower, and all access to the trailheads in the vicinity will remain open, including the trail to Andrews Bald. Visitors should expect some construction traffic in the vicinity of the contact station and along the trail.

The observation tower is a precedent-setting design of the National Park Service’s Mission 66 program, which transformed park planning, management, and architecture and fundamentally altered the visitor experience in national parks. Since 1959, millions of visitors have climbed the tower, where they can see distances of up to 100 miles over the surrounding mountains and valleys. Some minimal preservation work today on the tower will ensure that visitors continue to experience this unique structure spiraling up from the highest point in the park.

For more information about the Clingmans Dome Tower, please visit he park website at http://ift.tt/2gyHefi.

About Partners in Preservation: Partners in Preservation is a program in which American Express, in partnership with the National Trust for Historic Preservation, awards preservation grants to historic places across the country. Since 2006, Partners in Preservation, a community-based partnership, has committed $16 million in preservation funding to nearly 200 diverse sites in eight different cities across the country.

Through this partnership, American Express and the National Trust for Historic Preservation seek to increase the public’s awareness of the importance of historic preservation in the United States and to preserve America’s historic and cultural places. The program also hopes to inspire long-term support from local citizens for the historic places at the heart of their communities.

Programming Note: Friends Across the Mountains Telethon on Wednesday Night

This Wednesday, August 23rd, is the 23nd annual Friends Across the Mountains Telethon. The event will again be broadcasted on WBIR-TV Channel 10 in Knoxville, TN and WLOS-TV Channel 13 in Asheville, NC from 7:00 PM - 8:00 PM.

The broadcast will highlight projects and programs that Friends of the Smokies has funded over the years. It's a fun event that raises awareness of both the Park's needs (as the only major national park without an entrance fee), and the ways that Friends of the Smokies helps to fulfill some of those needs every year. The telethon raises roughly $200,000 each year, and has raised more than $3.5 million dollars over the last 20+ years.

Volunteers will be on hand to help answer phones and keep running totals of the money raised throughout the evening.

Smokies Reminds Visitors to Be Prepared for their Solar Eclipse Experience

Great Smoky Mountains National Park officials are urging visitors to review the Frequently Asked Questions information posted on the park’s 2017 Solar Eclipse website at http://ift.tt/2lPXpLN to assist in planning a safe solar eclipse experience.

Everyone is reminded to use only approved solar eclipse glasses when directly viewing the eclipse. Glasses can only be removed during the brief few seconds when in the area of totality. The duration of totality varies greatly across the park and region. A common cause of eye injury during a total eclipse is immediately following totality when viewers forget to put their glasses back on.

“A large number of people will be making Great Smoky Mountains National Park their destination for eclipse viewing on Monday,” said the park’s Chief Ranger, Steve Kloster. “We want to make sure everyone who comes here is as prepared as possible and understands that we expect traffic to be heavy and many park areas to be crowded. The better prepared our visitors are, the more enjoyable and safe the experience will be for everyone.”

Visitors should bring plenty of food and water and make sure their vehicle has a full tank of gas before entering the park. The high amount of traffic expected will cause difficulties for towing companies to reach vehicles in need. The traffic could also cause temporary road closures throughout the day as the park manages the influx of vehicles entering the park. Anyone planning to travel to or through the park should have an alternate route in mind in case the first path or viewing location is no longer available.

Visitors are asked to remember to respect the park and it’s wildlife by staying at least 50 yards from bears and elk and not feeding any park animals. Trash should be packed out or put in an appropriate trash receptacle to keep our overlooks and viewing areas clean. Backcountry hikers are reminded to follow Leave No Trace principles and to make sure they are prepared for the distance and mountainous terrain of their planned hike.

Visitors should also remember that Clingmans Dome Road will be closed to public access beginning at 11:00 p.m. on Saturday, August 19 through the evening of Monday, August 21 following the eclipse event. No overnight parking will be allowed at Clingmans Dome Parking Area or pull-offs, parking areas, and trailheads along the road during this time period. The road will be closed to all motorists, pedestrians, and bicyclists. The Clingmans Dome Trail will be open to the public, but the tower will be accessible to media only. The event at Clingmans Dome will be livestreamed at http://ift.tt/2vzVmRw.

Friends of the Smokies Announces $2.5 Million Emergency Radio Upgrade in Great Smoky Mountains National Park

In celebration of the organization’s 25th anniversary next year, Friends of the Smokies is delighted to announce a milestone capital campaign to fund a critical radio system upgrade in Great Smoky Mountains National Park (GSMNP).

The total cost of the radio system upgrade is $2.5 million. “Our target for this campaign is to raise $1.25 million by this time next year, making it our biggest fundraising goal in a decade,” said Jim Hart, president of the nonprofit organization. Federal funding sources and other grants will be used to match donations to Friends of the Smokies dollar for dollar to reach the total cost. “We know our generous supporters will rise to meet this challenge in spectacular fashion, especially when such a significant project is at hand.”

The radio communications system currently used in GSMNP has exceeded its recommended maximum lifespan. Replacement parts are difficult to come by and repairs and maintenance are costly on a tightening federal budget. The proposed project will replace microwave and repeater equipment at nine radio tower sites around the park as well as portable radio units and mobile units in patrol vehicles and fire engines. This will allow park rangers and emergency dispatch to directly communicate with police, fire, and emergency services in jurisdictions outside park boundaries including agencies in North Carolina and Tennessee. The total cost of the upgrade also includes a Computer Aided Dispatch system which allows dispatchers to prioritize and record emergency calls and locate first responders in the field.

Steve Kloster, Chief Ranger in GSMNP said, “The ability to effectively communicate with different agencies in the field can make all the difference in a life-threatening situation where every second counts. A good communications system truly is the backbone of any emergency response and this stateof-the-art upgrade will put the Smokies on par with any unit in the National Park Service.”

In addition to improving emergency response for law enforcement, search and rescue, and wildland fire, this upgrade will provide operable and dependable equipment for day-to-day operations across more than 522,000 acres of the national park. Where before, facility maintenance might share the same channel with an active search and rescue operation, the upgraded communication system will provide dedicated emergency frequencies.

“A new radio system is absolutely vital for responding to emergencies quickly and effectively, preserving the cultural and natural resources of this park, and protecting our visitors and first responders,” GSMNP Superintendent Cassius Cash added. “We are thankful to the Friends for their willingness to tackle this request head on and still provide funding for other needs across the park.”

“Delivery of a large-scale project like this radio system is the perfect way to celebrate our 25th anniversary next year,” said Brent McDaniel, marketing director at Friends of the Smokies. “Big, important projects like this are nothing new to Friends of the Smokies and we are excited to help protect 11 million visitors and keep our park rangers safe.”

Friends of the Smokies has contributed millions of dollars towards milestone projects including matching $2 million from the Aslan Foundation of Knoxville in 2008 to create the Trails Forever endowment. Now grown to more the $5 million, this endowment funds a full-time trail crew that focuses on rehabilitation of the park’s most heavily used trails, including Chimney Tops, Alum Cave, and Rainbow Falls. Recurring support from Friends of the Smokies to GSMNP for programs like environmental education, historic preservation, and wildlife management exceeds $1 million annually.

To make a matching gift to support this critical radio system upgrade, please visit Donate.FriendsOfTheSmokies.org or call 800-845-5665.

Blue Ridge Parkway Prepares for Total Solar Eclipse

Blue Ridge Parkway staff and volunteers are actively preparing for the solar eclipse on August 21, 2017. That day, from approximately 1:00 p.m. to 4:00 p.m., the eclipse will cross much of the southern section of Parkway on its journey across the United States. Weather permitting, visitors to this section of Parkway, from Milepost 417 – 469, will have the opportunity to experience 100% totality in approximately 17 overlooks. Additional overlooks in this section, and extending north of this area, will experience varying partial totality.

In anticipation of an unprecedented volume of visitors on the day of the eclipse, Parkway managers are asking anyone interested in experiencing the eclipse on the Parkway to plan ahead and follow these guidelines:

•Expect heavy traffic. Have plenty of patience and make sure you have full tank of gas. Rangers may implement short term closures if parking becomes full or roads become congested.

•Plan several options for viewing locations and get there early. If parking is full at your first choice location, move to another.

•Be prepared. In addition to special viewing glasses, visitors should bring food, plenty of water, a first-aid kit, flashlight, and provisions for changing weather.

•Pack it in, pack it out. To help protect park resources, visitors should pack out any trash generated during their time on the Parkway.

Additional information about what to expect and how to prepare is available on the Parkway’s website. On the day of the eclipse, the Parkway will use its Twitter channel for any updates or announcements.

The Blue Ridge Parkway is one of 21 National Park Service sites in the path of the eclipse. National parks offer a memorable setting for watching the eclipse; and during the eclipse, park rangers and volunteers will be on site at selected overlooks throughout the day reminding visitors about the many other ways to experience the Parkway’s natural and cultural resources throughout the year.

Shenandoah National Park To Host Night Sky Festival and Solar Eclipse Viewing

Shenandoah National Park will celebrate the importance of dark skies and the beautiful night skies that Shenandoah protects with the second-annual Night Sky Festival from Friday, August 18 to Monday, August 21. Join Park Rangers, special speakers, and local volunteer astronomers during four exciting days of talks, walks, audio-visual presentations, and sky viewing throughout the Park. The event will culminate with a viewing of the solar eclipse on Monday, August 21. Shenandoah and other national parks provide excellent opportunities to experience starry night skies and natural darkness. Join us to learn the basics of astronomy, discover the importance of protecting dark night skies, enjoy some close up views of stars and planets, and learn about eclipses.

On August 21, 2017, the final day of the festival, the 2017 Solar Eclipse will cross the continental United States. While Shenandoah National Park will only experience 80-85% coverage of the sun at approximately 2:40 p.m., and will not experience a total eclipse, it is still a great place to learn about and experience an eclipse. Join Rangers throughout the weekend and on the day of the eclipse to learn why a solar eclipse happens, what to expect, and how to view it safely.

Activities will take place in a variety of locations throughout the Park. For a complete list of the weekend’s events, see the Night Sky Festival schedule. All programs are free. There is a $25-per-vehicle entrance fee to the Park which is good for seven days.

Participants are encouraged to dress for cool mountain nights during evening activities and bring blankets, chairs, and flashlights for stargazing. Night sky viewing may be canceled depending on cloud cover or inclement weather.

Pourquoi et comment oublions-nous ?

Salut à tous,  


Du site The Conversation : 

   ¨ Oublier semble être une chose que le cerveau fait facilement à notre insu. Pour preuve, nous oublions tous des rendez-vous, des dates d'anniversaire et des compétences. L'oubli est même utile s'il s'agit d'un souvenir douloureux ou obsolète.

   En fait, c'est tout l'inverse : nous n'oublions jamais rien. On ne se rappelle plus, c'est tout ! Nos neurones ne font que mémoriser, et ce tout au long de leur vie, qui est aussi longue que celle de l'individu. La mémorisation se fait à plusieurs niveaux dans le cerveau, mais le plus connu est celui de la jonction entre deux neurones : La synapse.

    La règle de Hebb caractérise donc l'apprentissage, mais elle caractérise aussi de facto l'oubli.

Inhibition des neurones !  
   La règle de Hebb concerne tout aussi bien les connexions excitatrices (A excite B) que les connexions inhibitrices (A empêche B d'être excité). L'inhibition concerne 20 % des neurones de notre cerveau, et elle est fondamentale. De nombreuses pathologies graves (notamment l'épilepsie) sont liées à une moindre efficacité des connexions inhibitrices. Ces connexions sont difficiles à étudier : comment mesurer, en effet, quelque chose qui n'a pas eu lieu ?
 
L`oubli, une affaire de cortex !      
    Pourquoi est-ce que l'on oublie de se rappeler ? Répondre à cette question impose de comprendre la mémorisation d'un événement. Un souvenir est codé principalement par le cortex, qui représente 80 % de la masse du cerveau, mais seulement 20 % des neurones (soit 16 milliards). Le cortex consiste en une hiérarchie de 360 cartes corticales, au sein desquelles se répartissent les 160 000 colonnes corticales (composées de 100 000 neurones chacune).

Mémoire épisodique et mémoire sémantique !      
    On appelle état d'activation global (EAG) l'ensemble de toutes les colonnes actives à un instant donné. L'EAG est la représentation corticale de notre souvenir. Deux dimensions appartiennent à tous nos souvenirs : la date et le lieu de l'événement. Une structure spéciale - l'hippocampe - gère ces deux informations grâce aux time cells et aux place cells (CA1 et CA¨...

Shenandoah National Park Announces Temporary Trail Closure during Helicopter Operations

Shenandoah National Park managers will temporarily close the area surrounding Corbin Cabin (see closure map, red rectangle) to all hiking and backcountry use during helicopter operations associated with the restoration of the historic cabin. Since the cabin is located in a remote area, a helicopter will be used to remove construction materials related to the project.

The temporary closure will be in effect from 6:00 a.m. August 8 through 6:00 p.m. August 11. The closure area is located southeast of Skyline Drive (mileposts 37 and 38) in the vicinity of the upper Nicholson Hollow/ Corbin Cabin Cutoff Trail. Trails closed include all of the Corbin Cabin Cutoff Trail and the Nicholson Hollow Trail from the intersection of the Indian Run Trail eastward to 1/4 mile east of the Corbin Cabin. There will be no closures on Skyline Drive or the Appalachian Trail.

As soon as the project is completed, the temporary closure will be lifted.
