Breaking news: Devil's Den will reopen Friday after six-month rehabilitation project, Gettysburg park officials say

Devil’s Den, scene of fierce fighting during the July 1863 battle, will reopen on Friday after a six-month project that tackled erosion and unauthorized trails that created safety hazards, Gettysburg National Military Park announced Thursday.

The project reestablished the features that make up this segment of the battlefield and will allow visitors to better immerse themselves into the historic landscape that is essential to understanding the three-day Battle of Gettysburg,” park said in a social media post.

The work tripled trail access to those with disabilities, increased overall greenspace by trimming some trail space and added features that will help with water runoff. Slip-resistant steps replaced uneven and worn stone steps, officials said.

“Although the area will reopen to visitors, one central area will remain fenced to allow more time for further vegetation growth. The fencing in this area will remain until native grasses have fully established. This process may take up to two growing seasons – up to 2024. In the interim, all non-native vegetation will continue to be treated within the entire project area.

The reopening comes amid similar work on Little Round Top, which closed to visitors in July. “The rehabilitation of Little Round Top will address overwhelmed parking areas, poor accessibility and related safety hazards, significant erosion, and degraded vegetation,” the park said.

After the park earlier this year announced the Devil's Den closure in a Facebook post, critics and supporters weighed in. One said the need for work at both areas has been known for years and the public will be disappointed that two landmarks would be closed at the same time. Others said people should be grateful the work is happening to perpetuate the memory of those who fought there.

Park spokesman Jason Martz told the Picket in a March email that the timing of the projects was a coincidence, but they are both meant to address problem areas.

Devil’s Den was the scene of fierce fighting on July 2, 1863, during the decisive battle. The boulder-strewn hill was the object of forces under Confederate Lt. James Longstreet. Rebels took the position and engaged in fire with Union troops on Little Round Top.

Volunteers recently assisted the park with clearing vegetation overgrowth at Devil's Den as it neared reopening. Park officials then treated stumps to prevent sprouting.

A second landmark at Gettysburg National Military Park will close for several months this year for major rehabilitation.

Park officials announced Thursday that work at Devil’s Den is expected to begin on March 21. The closure will last five to six months as crews address “significant erosion and safety issues in this highly visited area of the battlefield.”

Devil’s Den was the scene of fierce fighting on July 2, 1863, during the decisive battle. The boulder-strewn hill was the object of forces under Confederate Lt. James Longstreet. The Rebels took the position and engaged in fire with Union troops on Little Round Top.

The park said the work is needed because of the erosion along existing walkways and from unauthorized social trails that have created safety hazards.

“The scope of the project will reestablish, preserve, and protect the features that make up this segment of the battlefield landscape,” it said in a statement. “These improvements will allow visitors to better immerse themselves into the historic landscape that is essential to understanding the three-day Battle of Gettysburg.

Crawford Avenue, Sickles Avenue and the Devil’s Den parking area will remain open as much as possible for visitor use. Adjacent battlefield locations, such as the Slaughter Pen, Devil’s Kitchen, and the Triangular Field, will all remain open. The construction contractor will occasionally need to close all road access around the area, but notices will be posted ahead of time, the park said.

The announcement came about a month after the National Park Service detailed a rehabilitation project on Little Round Top, where Union forces fought off a furious Confederate assault, also on July 2.

Park officials said they are addressing ongoing problems at the overcrowded site. They cited erosion, overwhelmed parking areas, poor accessibility and related safety hazards, and degraded vegetation.

“This project will also enhance the visitor experience with improved interpretive signage, new accessible trail alignments, and gathering areas. These improvements will allow visitors to better immerse themselves into the historic landscape that is essential to understanding the three-day Battle of Gettysburg,” a news release said. 

An update this week said tree cutting was completed last month and the overall project is out for bid, with two contracts: one for overall construction and the second for revegetation of Little Round Top.

The closure of Little Round Top is expected to begin sometime between March 20 and June 21. The project will take up to 18 months to complete, officials previously said.

Gettysburg's famed Little Round Top will be closed 12-18 months during project addressing erosion, parking, accessibility and more


Tree cutting this month at Little Round Top will kick off a larger rehabilitation project that will include a 12-18 month closure of the hill where Union forces fought off a furious Confederate assault, Gettysburg National Military Park announced Tuesday.

Park officials said they are addressing ongoing problems at the overcrowded site. They cited erosion, overwhelmed parking areas, poor accessibility and related safety hazards, and degraded vegetation.

Once rehabilitation efforts begin, all of Little Round Top will be closed for 12 to 18 months, the park said. Officials said Wednesday they were unable to provide details on the exact timing of the beginning of the closure, other than "later in Spring 22."

“This project will also enhance the visitor experience with improved interpretive signage, new accessible trail alignments, and gathering areas. These improvements will allow visitors to better immerse themselves into the historic landscape that is essential to understanding the three-day Battle of Gettysburg,” a news release said. 

A park page on the project says the aim is to “reestablish, preserve, and protect the features that make up this segment of the battlefield landscape.”

Little Round Top and Sykes Avenue will be closed Feb. 9-11 and Feb. 14-16 for the cutting of up to 63 trees along both sides of the road. The park says the removal is necessary for the project.

The work is happening now so as not to interfere with the nesting and breeding of northern long-eared and Indiana bats that may roost in the area. “Both species of bat are on the federal endangered species list and the select tree cutting project must be completed before their anticipated arrival in early spring when nesting activities typically begin.”

Little Round Top is the location of some of the most famous fighting of the battle

Rising 164 feet above the Plum Run Valley to the west, the boulder-strewn hill became the anchor of the Union’s left flank and a focal point of Confederate attacks on the afternoon of July 2, 1863.  The 4th,15th and 47th Alabama regiments made a series of legendary assaults against the 20th Maine, led by Col. Joshua Chamberlain (right).    

“The (Maine) regiment’s sudden, desperate bayonet charge blunted the Confederate assault on Little Round Top and has been credited with saving Major General George Gordon Meade’s Army of the Potomac, winning the Battle of Gettysburg and setting the South on a long, irreversible path to defeat,” according to the American BattlefieldTrust

Cockspur lighthouse at Fort Pulaski emerges from scaffolding after months of preservation work. Here's what was done on beacon

(All photos are recent and from Fort Pulaski National Monument)
Fort Pulaski National Monument near Savannah, Ga., this week completed a five-month project aimed at protecting the small but resilient Cockspur Island Lighthouse from moisture and tides.

The 46-foot structure, built in 1855, has endured high tides, hurricanes, waves from ever-growing container ships, vandals and – for a deafening 30 hours – the April 1862 bombardment of nearby Fort Pulaski during the Civil War. 

The Union’s strategy was to put a chokehold on Southern commerce by controlling ports and coastal areas, including this area next to the Atlantic Ocean. Federal soldiers landed at Tybee Island and set about preparing for an attack on Pulaski, a brick guardian to the west.

Remarkably, the lighthouse suffered little or no damage. Crews manning 36 guns on 11 batteries stretching along the western end of Tybee likely used the lighthouse for sighting as they pounded away at the fort. The Confederate garrison, worried that exploding shells might reach munitions, surrendered within a day.

Louvered transoms on door, windows allow ventilation
The park over the years has undertaken work aimed at protecting the beacon. The Picket has communicated with Emily Forlenza, exhibits specialist and acting facility operations specialist at Fort Pulaski National Monument, about the project. Here are her emailed responses to questions, edited for brevity.

Q. Would you mind briefly summarizing all the work was done?

A. For this project, the masonry tower, stairs, keel, window and door openings, and interior of the Cockspur Island Lighthouse were cleaned, chiseled and repointed. These efforts were undertaken due to the damage that this structure sustained from tidal action. The mortar that was used was a match to what we believe was used historically, based on lab testing, material sampling, and test patches used in various areas. Most of the efforts for masonry repointing took place on the exterior of the structure, as that is where the most wind and water action is seen. The interior masonry also saw this repair work as well, but it was not as extensive. Additionally, the door and windows on the structure were replaced using materials and a configuration that are believed to be the configuration and material of the original fixtures. The only update to these new additions was to add a louvered transom instead of a fanlight above the door and windows. This was done to allow for passive ventilation through the structure, since it is closed most of the year due to its remote location. In total, we replaced one entry door and transom, three 6-light windows with transoms, and two porthole windows. 

Q. In October, you mentioned work “toward getting the light back on.” What do you mean?

A. Since this lighthouse is located in a major shipping channel, we want to make sure that no vessel would confuse this with an active aid to navigation (ATON.) We are planning to work closely with the Coast Guard to get the light back up in the lighthouse, facing out in the direction where ships will not be able to confuse their navigation. We are hoping this will come shortly, within the next few months. (The lighthouse was last used as a lighted beacon in 1909)

Q. Did anything require total or partial replacement?

A. The door and windows all required total replacement. We did not have a functional door at all, and what was in place for all of the openings was neither original nor historic. 

Q. What painting was done?

A.
The cupola of the lighthouse was painted with a rust reformer and black metal paint in order to restore its appearance. The old cupola is located in front of the visitor center of Fort Pulaski, having been removed due to its state of deterioration in 1995. (See comments section below for why exterior of lighthouse was not painted)

Q. Will the lighthouse remain closed to the public?

A. This is a topic of discussion among Fort Pulaski staff, but for the foreseeable future it will remain closed.  

Q. How did the lighthouse fare during the recent super high tides? I know higher water levels have been of concern for a time.

A. The lighthouse itself held up very well, as she always does. None of our new repair work showed any sign of failure, and the new door and windows we put on look as good as they did the day we put them on.

Q. How will you regulate or manage moisture issues?

A. As stated above, the passive ventilation that is offered by the louvered transoms is our main mitigation against the stagnant damp air that would typically cause issues inside the structure. 

Q. You anticipated the project would cost about $150,000. Did that prove to be true?

A. Yes, we came in right around our anticipated budget. (Funding for the fabrication of the door and windows came from a grant given to the Friends of Cockspur Island Lighthouse by the Tybee Island Historical Society, which was matched by NPS Centennial Challenge funding.)


Q. Can you tell me about the replacement mortar being historically accurate? How so?

A. Historically, the mortar used for the lighthouse would have had a heavy makeup of natural cement due to its location being heavy impacted by the tides. During testing, it was determined that this was true. The park then did test patches to make sure that the mortar was going to hold up in this area. Even though the mortar was historically accurate, we still wanted to make sure that this would be the best fit for the structure. 

Q. What work was done by NPS staff and what was done by contractors?

A. The National Park Service provided all of the day labor and craft skills required to repoint the structure, paint the cupola, and install the door and windows. The door and windows were fabricated by Savannah Millworks, a local company here in Savannah. The scaffolding that was constructed around the structure was also contracted out, by Sunbelt Rentals. 

Q. Any hitches or pleasant surprises or finds during the work?

A. The most fascinating part of working with historic structures in these historic settings is coming up with unique ways to start these projects off. The planning process was the most interesting part initially, because we needed to figure out how we were going to get sturdy enough scaffolding around a structure that was surrounded by huge boulders (revetment, to protect the island from erosion) while at the same time ensuring that the structure would be protected during tidal surges from the scaffolding swaying or moving in any way. We had to figure out how best to get a crew of 5-6 people out to the lighthouse every day safety and efficiently, while factoring in tides that would change where we could get the crew on and off the island.

And probably the most unexpected hitch: the crew shared the lighthouse with a very disgruntled barn owl for about a month, before the owl decided it was time to find a new home. He did continue to torment the crew each day upon their arrival until he moved out. 

Q. Any other thoughts on the project?

A. This project gave us an incredible amount of information that we are going to be using to develop future projects for the preservation of this structure. 

Projects like these are essential for future project development. It is such a unique experience to be directly involved in work like this, and I am thankful that my crew and I were able to take part in preserving this structure for future generations.
