Not quite the lighthouse. Not quite the Transpeninsular Line. The cache is close but is in Maryland. The lighthouse was built in 1858 and cost $23,748.96. It is only open 5 months of the year on a very limited basis. Currently well maintained by the Friends of the Fenwick Lighthouse, the light is now electric although it was originally whale oil and then kerosene. The fresnel lens used for magnification was imported from France. The two houses flanking the lighthouse were the homes of the lighthouse keeper and his assistant and are now privately owned.
The stone marker is the eastern end of the Transpeninsular Line surveyed 1750-51 by surveyors from Pennsylvania and Maryland. It settled a dispute between the Calverts (coat of arms on the south side of marker)of Maryland and the Penns (coat of arms on north side)of Pennsylvania's 3 lower counties (now Delaware). It was accepted in 1760.
You will not need to tred on private land or lighthouse property no matter how welcoming it is. Please be aware of the many tourists stopping in their cars or walking here. Watch traffic!
Please remember that some geocachers are vertically challenged (short). DO NOT place the cache so high that our fellow geocachers are unable to reach it.
