No word yet on how Antietam weathered the storm. Other parks reported this on FRIDAY:
Petersburg NB – Major tree damage occurred, and downed trees are blocking roads throughout the park. Some are entangled in power lines. Power is out.
Richmond NB – The hurricane caused serious tree damage throughout the park. Many roads are blocked. Power lines are down, and there was no electricity as of Friday. Damage to structures appears to be limited, but one government Chevy Tahoe was flattened by a falling tree. The park remains closed.
Appomattox Courthouse NHP – The park was closed until noon Friday due to storm damage and lack of power, but reopened that afternoon (except for the Courthouse, which serves as the park’s visitor center. Power is out throughout the county and will likely not be restored for seven to ten days.
Shenandoah NP – The center of Hurricane Isabel passed over the park as a strong tropical storm during the early morning hours on Friday morning. On Saturday, crews worked to clear an access route to frontcountry facilities and to conduct an initial size-up of damage to structures and utilities. An emergency access route was established for the entire length of Skyline Drive. With one exception, no structures in the frontcountry were found to have received more than minor damage. One concessions-owned building received moderate damage. The condition of Camp Rapidan and all backcountry structures remains unknown. Although the park remains without power and phones (except at headquarters), the extent of damage to utility lines remains unknown. The entire park remains closed. Many employees remain without utilities and some are stranded behind fallen trees and/or high water, but all seem to have faired well.
Fredericksburg/Spotsylvania NB – The storm caused extensive damage to trees throughout the park. Roads are blocked, and there’s no electricity. The park is closed.
George Washington Birthplace NM – The park sustained major tree damage.
Chesapeake and Ohio NHP – Damage assessments are focusing on the lower 24 miles of the canal. It will take several days to complete them. The towpath is closed to traffic; there were about 80 downed trees and several damaged structures.
Manassas NB – Power is out to the visitor center and maintenance facility and radios are out, but no structural damage is apparent.
Harpers Ferry NHP – The park has downed trees and is without power, but there was no significant street damage. The Shenandoah River was expected to crest at 20.4 feet on Saturday, which would not be high enough to flood buildings.
Catoctin MP – Significant tree damage occurred throughout the park, and power was knocked out on the east side. Two historic cabins suffered major damage – one was collapsed by a falling tree, the other sustained porch damage. Five other cabins were also damaged.
