Planning Your Visit

For this adventure, you’re headed to the lime kiln in Silver Mine Park at Click here for directions.

From the parking lot, it’s a short 100-yard walk to the lime kiln. This is a great lime kiln to explore. For starters, it’s open to the public. Also, you can examine the kiln from both the top and bottom.

Silver Mine Lime Kiln

This is a two-kiln structure typical of those that dotted the region in the 1800s and early 1900s. The collapse of the north kiln allows inspection of the inner crucible-like shape. In operation, the kiln was filled with alternating layers of wood and limestone or dolomite. This was lighted and allowed to burn freely for a brief time before being covered at the top by dirt and ash and the flow of air-restricted by dirt piled around the bottom inlet.

For about a week, this burn was watched constantly to allow just enough gas from the limestone and the combustion to escape while the intense heat was maintained inside the kiln.

After about a week, all the wood was burned and all the carbon dioxide was driven out of the limestone to leave the rocks as quicklime, a white powdery form of calcium oxide.

This was dug out the opening at the bottom to be mixed with water, sand, and rock to
produce mortar and cement for walls. It also could be made into whitewash paint for barns and houses or used as a powder to disinfect the ubiquitous privies of that time. Most of the dolomite for the kiln probably came from the large quarries visible through the trees just across Silver Mine Run to the east.

Finding the Treasure Cache Hard

If you’re the type of person who doesn’t like directions, here’s the GPS location of the treasure. When you get there, look under the bridge. Good luck!

Finding the Treasure Cache Easier

From the parking lot, take the orange trail north. After a brief walk, you will see the double lime kiln on your left.

Continue north on the gravel path past the old silver mine entrance. The nuts that hold the steel plate over the entrance have been welded on. Makes me wonder who they are keeping out or what they are keeping in.

At the pond, go left and then right on the orange pond trail.

When you get to the pond, go left. Immediately after that, the trail splits again. Take the path on the right next to the pond.

Continue along the pond trail until you come to a bridge. This is where you will wish you had worn those water resistant boots.

Look beneath the bridge to claim your prize. What’s inside the briefcase? There’s only one way to find out!

Be sure to return the case where you found it for future adventurers to discover.

Returning Home

Before heading home, be sure to discover more of the park. There’s so much more to see. I would highly recommend exploring the yellow geology trail. There’s an abandoned mine tunnel to crawl through. You can learn more about the 300-year-old Pequea Silver Mines here.

This is where you will want that flashlight.
