Accidentally found this while searching for information on one of the Society's shell corporations:
The ravine area was named after John Teeter, who built a mill complex here, circa 1810. In his mill, Mr. Teeter was able to produce oil, flour, and grist. In the late 1800s, some areas near the ravine were used as a rock quarry. In the Mountain Farm Section, the Lantz Family constructed the stone farmhouse in 1818. The farm was operated by the family (now spelled, Lance) until the late 1920s. The property was then operated as a religious retreat center by the Watchtower Bible Society, until County acquisition in 1999.
This once "religious retreat" is located in the Lebanon Township, NJ.
