It’s been nearly eight years since a storm of historic proportions pounded Death Valley National Park and did extensive damage in Grapevine Canyon in the northeastern corner of the park where Scotty’s Castle stands. The popular tourist attraction still has not reopened as repair work continues.   That storm was described as a once-in-a-thousand years storm.   A year ago, rainstorms again pounded Death Valley. In roughly three hours 1.5 inches of rain fell on the park and did considerable damage to roads and water systems and shut down the park. That storm also was described as a once-in-a-thousand-years storm.   Another powerful storm hit Death Valley National Park two weeks ago. On August 20, 2.2 inches of rain fell at Furnace Creek, according to the National Weather Service, making it the rainiest day on record in the park. For some perspective, during a full year the park usually sees only 2.15 inches of rain.   To discuss these storms and how the National Park Service is responding to them we’re joined today by Abby Wines, the park’s management analyst.
