The Stumphouse Mountain Tunnel penetrates about 1,600 feet into the mountain in northwestern South Carolina near Walhalla, then ends at a brick wall and a rusty iron gate. We trudged the full length of it with flashlights, inhaling the cool damp tunnel air, stepping carefully along the muddy floor. We reached the end and squinted through the gate into a black void.
The state government’s plan in 1855 was to build the tunnel, 5,860 feet long and 236 feet deep, through the southeast face of Stumphouse Mountain in order to lay track for a route from Anderson, S.C., to Knoxville for use by the Blue Ridge Railroad. The idea was to benefit businesses in Charleston that wanted a shorter trip to Ohio than the complicated route through central Georgia and Tennessee.
Something like 1,500 workers, mostly Irish immigrants, and their families settled in a work camp called Tunnel Town which, it was said, had “more saloons than churches.” A Catholic priest arrived and, appalled at the conditions, persuaded the site boss to fire any worker who got drunk. He built a church, St. Patrick’s, the first Catholic church west of Columbia, to serve the workers.
The Irishmen hacked away at the steel-hard blue granite with hand drills, hammers, and chisels. Because of the hardness of the granite the workers could get through only about 260 feet per month. The work went so slowly the money ran out and the work stopped. The men of Tunnel Town drifted away.

While the state and the builders looked for new funding the Civil War began. After the war the state had neither the interest nor the money, and the project was abandoned. St. Patrick’s church eventually was destroyed by fire and scavengers.
The tunnel is said to be one of the most visited parks in the state, which seems odd for an unlit shaft through solid granite 1,600 feet long, in a state of many beautiful places.
The story of the tunnel’s name is as strange as the name itself. We learned it derives from a legend of no specific timeframe: a Creek woman named Isaqueena who had been captured by Cherokees fell in love with a white man who lived in Greenwood County, about 90 miles south of Walhalla. When she heard the Cherokees planned an attack on his settlement she escaped with the fellow, the two hid in a large hollow tree, hence “Stumphouse.”
This version is based on a poem written by a Rev. J.W. Daniels in 1898 entitled “Cateechee of Keowee,” which says Isaqueena’s name was changed to Cateechee. She later escaped the Cherokees by pretending to leap into a waterfall near the tunnel, now called Isaqueena Falls.
The next chapter gets even stranger. Sometime around 1940 a professor at nearby Clemson University (then Clemson A&M) guessed the cool, moist tunnel air would be perfect for curing blue cheese. Yes, cheese. He passed the idea along, and the school’s Dairy Department (yes, there was one) started research on methods of making blue cheese.
In 1951 Clemson bought the Stumphouse Tunnel and commenced Operation Blue Cheese. The cheese was made at the school using milk from the college’s herd of cattle, and shipped the 30 miles to the tunnel for curing. I read that in 1953 2,500 pounds of Clemson blue cheese was cured in the tunnel. By 1956 the Clemson Dairy Research department had built a climate-controlled space and the needed equipment. The curing process was brought on campus in 1958 and the tunnel was again abandoned.

Today, the university says, the school’s cheese department (Department of Food, Nutrition, and Packaging Sciences) sells 25,000 pounds of blue cheese annually. Clemson leased the tunnel to the Pendleton Historic District Commission, which turned it into the park site.
We had driven over to Walhalla with the grandsons, the idea being, as it often is, to see unusual places, to recharge, but now also to break away from war news. The tunnel park is a few miles north of town on U.S. 28, which curls into rugged country towards the North Carolina state line. It was sunny but chilly.
We drove down a winding access road through thick woods to the parking area. We climbed the steep hill to the tunnel entrance and took a few uneasy steps inside. The shaft is 25 feet high and 17 feet wide. We turned on our flashlights and moved forward across the muddy floor, cringing as cold water dripped on our heads from the overhead.
As we walked slowly through the darkness, we navigated the rough ruts and ridges of the tunnel floor, which along the walls is covered with water. The sunlit entrance receded behind us. Soon we could make out the locked rusty gate that prevents further progress. We peered through the gate, the tunnel extends further into blackness. We took deep breaths and turned and headed back to daylight.
We walked back down the hill, glad and relieved to feel the sun’s warmth. We found a picnic table, got out our sandwiches, and ate lunch. We noticed a few other visitors, who wandered up the hill toward the tunnel entrance.
The boys and I walked the quarter-mile along a steep trail to the falls. We peered over a ledge at the rushing water, which disappeared into the forest below. Looking out maybe 60 miles at the horizon, we could perceive the change in the terrain from the rugged northwest to the gentle roll of the central Piedmont, which miles farther extends into the flatness of the coastal Low Country.
We stopped at a cute place in Walhalla for ice cream. A chess set sat on the table, the boys played. The shop owner and a few customers chatted. We relaxed, letting the afternoon tension settle.
As we sat waiting for the boys I recalled Sandy and I had driven out to Walhalla about a month after we settled in our Greenville apartment. I was getting over surgery. We looked at homes in a lovely old neighborhood. We knew it wouldn’t work, nearly two hours from the city, the hospital, the kids. But it was lovely. Strange, but lovely.
