After the surprise success of A New Hope, a sequel was inevitable. Lucas’s new story turned the series into a dramatic saga with the revelation that Darth Vader was Luke’s father. Since making the last film had been so stressful, he had Lawrence Kasdan and Leigh Brackett write the script for The Empire Strikes Back and had Irvin Kershner direct it.
- Lake Shannon (Wikipedia)
Lake Shannon is a long, narrow reservoir on the Baker River in Skagit County, Washington in the United States. Formed in the 1920s by the construction of an arch dam just above the town of Concrete, the lake is approximately 7.5 miles (12 km) long and averages 0.6 miles (1 km) wide when full. Located just outside the western boundary of North Cascades National Park, Lake Shannon serves as the lower reservoir for Puget Sound Energy’s Baker River Hydroelectric Project.
