Note: This is an "EXPLORATORY" trip. This means that there are parts of this trip, or perhaps the whole trip, that is new to your Trip Leader(s). However, they are confident that this will not be an issue.
This note is here so that you can make an informed decision. When a Trip Leader isn't personally familiar with a trip, there is an increased chance of things not going as planned and you need to be prepared. The Trip Leader may have additional details in the itinerary.

Itinerary:
Tiptoe across airy ridges, spot resident black bear, and take in the best of the Smokies on this three-day, two night 28 mile loop.  
 
We begin at the Tremont Institute on Middle Prong Road near Townsend, TN and ascend the West Prong Trail through hardwood forest peppered with mountain laurel thickets (in June their branches are hung with white and red "peppermint" blossoms)
 
We continue on the Bote Mountain Trail, climbing more than 3,000 feet over 9 miles. Heading past Cold Water Knob, enjoy the northwest vistas into the rolling meadows of Cades Cove. 

Near the top of the climb, the trail enters tunnels of rhododendron. As we emerge onto the crest of the ridge, we'll turn right onto the Appalachian Trail, then take an immediate right toward the stone Spence Field Shelter.  Complete with a fireplace and spring, the shelter is equipped with cables to hang our food out of reach of black bears—just don’t forget about smaller pests. 
 
With an early start the next day we backtrack on the AT.  We continue to some of the Smokies best known peaks: 5,441-foot Rocky Top and 5,527-foot Thunderhead.  We'll take in the long-distance views from the ridge, then dip into a saddle before ascending through wind-stunted trees to Thunderhead. We climb the summit cairn for views over neck-high vegetation, then reenter the beeches. Water is available at the Derrick Knob Shelter if we need to hydrate or want a place to take a break.  
 
We turn left on to the well-graded Greenbrier Ridge Trail. We'll continue to the Lynn Camp Prong Trail and turn right (looking for tracks of reintroduced elk) and hike ~1.5 miles to secluded Campsite # 28, Marks Cove. This site accommodates both humans and horses overnight. It has a stream to refill water, hitching posts for horses, a fire ring, several crude log benches, and hoists to keep our packs out of bear range.
 
Next morning, we backtrack to the last intersection and turn right onto Middle Prong Trail, showcasing the emerald-green pools below Lynn Camp Falls. We gradually descend along the river to Tremont Road and road-walk the final 3.1 miles to close the loop. 
 
Day 1 - approx. 9 miles
Day 2 - approx. 12 miles
Day 3 - approx. 7 miles
 
This is a demanding backpacking trip.  For safety reasons, Trip Leaders will be screening anyone who does not appear to have adequate backcountry experience.  This may result in removal from the attendee list.     

Required Items to Bring:

Tent, sleeping bag, sleeping pad, appropriate clothing for winter backpacking, rain gear, headlamp, cooking utensils, food and water, PMA (Positive Mental Attitude), Sense of Humor!

Please bring sufficient cash to cover permit costs and car pool costs if you plan to travel as a passenger with another attendee.  The $64 Permit Fee Total will be divided equally amongst the number of attendees.

 

Recommended Items to Bring:
Use our Event Checklists to make sure you have everything you need.

Camera, hat, water filtration system, beverage of choice if you're so inclined, fire starter, first aid kit, sven saw, gifts for Trip Leaders

 

 


How to Get There:
Event Directions:

From Atlanta take I-75 N to Lenoir City - exit #81. Follow 321 North
through Maryville to Townsend. Go straight on Hwy. 73 (don't turn toward Pigeon Forge) into the Great Smoky Mountains National Park.

ONCE IN THE PARK: When coming in from Townsend, follow the road to the Y-intersection with signs to Gatlinburg or Cades Cove. Turn right towards Cades Cove, then immediately you will see a sign indicating the road to the Great Smoky Mountains Institute. Turn left across the bridge and follow the Tremont road 2 miles (you will cross two, two-lane bridges) to the Institute turning left across the 1-lane bridge. Office is on the left. We will check in.

Carpool to Event Distance (round trip):420Mile(s)
Carpool Departure Time: 6:30 am
Carpool Location:   Log in for location
Carpool Directions:   Log in for directions
Carpool Cost: Estimated cost per vehicle for this event is $168.00 using a reimbursement rate guideline of $0.400 per mile. The total amount should be divided by the number of people in the vehicle, including the driver. This is a guideline, not a rule, for drivers but the cost should not be higher unless there are extenuating circumstances.

Please note that Townsend, TN has an elevation of 1,066 ft.  We will be at higher elevations and therefore temperatures will be colder than those listed below. For example, Spence Field Shelter has an elevation of 4,915 ft.  You can use this formula to estimate what the temperature change will be with elevation:

http://treelinebackpacker.com/2013/05/06/calculate-temperature-change-with-elevation/

Equation   

( 3.5 x Change in elevation) = temp loss due to elevation change

 or (3.5ΔH=Tf)

You will lose an average 3.5 degrees Fahrenheit for every 1000 feet of elevation you gain. So, for Spence Field Shelter:

(4,915 - 1,066)/1000 = 3.849 {This is the Change in Elevation multiplier}

3.5 x 3.9 = 13.7 {This is the temp loss due to elevation} 

If we use the Daily Normals for our Friday, March 11 stay at Spence Field Shelter:

57.9 - 13.7 = 44.2 {This is the average high temp at Spence Field Shelter}

32.9 - 13.7 = 19.2 {This is the average low temp at Spence Field Shelter}

We can expect temps to be even colder at night.  Other factors will impact the actual value of these calculations.  Cloud cover will trap in more heat, whereas a clear sky will drop the temperature slightly faster.  Cold fronts and air streams may also have an effect, as well as local evaporation cooling. These factors are too numerous to account for, so the equation is designed as a worst case scenario calculation (after rounding).
