Head of Arizona park to become Rocky Mountain superintendent

The current superintendent of Saguaro National Park in Arizona will become the next superintendent of Rocky Mountain National Park in Colorado.

The National Park Service says Darla Sidles will begin her new assignment on Aug. 7. Her appointment was announced Monday.

Sidles is a 26-year Park Service employee who previously was deputy superintendent of Independence National Historical Park in Philadelphia. Before that she served at Grand Canyon Parashant National Monument in Arizona as superintendent and assistant monument manager.

Sidles will take over leadership at Rocky Mountain from acting Superintendent Ben Bobowski, the park’s chief of resource stewardship.

Bobowski has overseen park operations since October 2015, when longtime Superintendent Vaughn Baker retired after 42 years with the Park Service.
