Figure 6

Block diagram illustrating shallow angle thrust fault, structural fold surficial traces, and bedding planes at Sugar Run in Bradford County. The positions of water wells 1-6 (Paradise Road) and gas wells Welles 1-5 series are shown with the gas wells projected to the front of the block. In September 2010, gas was observed bubbling from the Susquehanna River, between the Wyalusing and Sugar Run communities, which ceased after the completion of gas well remedial activities. Modified from Llewellyn et al. [13]. View is toward the west.
