Task: Question Generation
Input (English): Passage: In 2004, the Loyalsock Creek Watershed Association installed a fence on the creek's banks near the cabins to limit pedestrian access and erosion. The association planted shrubs and trees in the same area to stabilize the creek's banks in 2008, and in September 2010 replaced more than 1,500 feet (460 m) of fence with a less visible version. On January 25, 2010 flooding caused by heavy rain and melt from 20 inches (510 mm) of snow "washed out a bridge" leading to the cabin area and destroyed 86 feet (26 m) of road there, leaving the park looking like "the set of disaster movie". The cabin area road needed $72,120 in repairs, the park was not fully restored until Memorial Day. Two floods hit the park in 2011, the first from Hurricane Irene on August 29, and the second from Tropical Storm Lee on September 8. Lee washed away about 20 to 22 short tons (18 to 20 t) of gravel used to make emergency repairs to roads in the park from Irene damage. Loyalsock Creek reached 20.4 feet (6.2 m) south of the park, and campers in the park had to be evacuated. Worlds End and Promised Land State Park had "significant damage to roads and bridges", damage to Loylasock State Forest roads was also heavy, and the DCNR estimated the two storms caused $3 to $4 million of damage to its forests and parks. Worlds End was closed for two weeks after the Lee flood.As of 2012, post-war facilities include the park office, five wash-houses and other modern restroom facilities, beach house with concession stand, chapel, amphitheater, and modern camping areas. Worlds End State Park is one of twenty-one chosen by the Pennsylvania Bureau of Parks for its "Twenty Must-See Pennsylvania State Parks" list. The DCNR describes it as "[v]irtually in a class by itself, this wild, rugged and rustic area seems almost untamed". It goes on to praise the opportunities for camping and hiking at the park, and its scenery and vistas.
Output (English): What storms did the DCNR estimate caused $3 to $4 million of damage to the forests and parks?
