Aided by canine teams and a drone, searchers in Zion National Park in southwestern Utah continued Saturday to search for a woman missing since she got off a park shuttle at the Grotto trailhead on October 6.

Missing hikers have been the subject of searches in Mount Rainier National Park in Washington and Zion National Park in Utah.

According to the National Park Service, there are over 5,000 miles of paved roads through the National Park System. Park roads (paved or unpaved) allow us to reach amazing vistas we might not otherwise see within a national park, national monument, or national recreation area. These roads are marvels of construction and merit a nod of appreciation to those builders who may have risked life and limb to ensure completion of that navigable ribbon of gravel or pavement. How many of these roads have you traveled, what have you seen and accessed via these roads, and how much do you know about them?

Vandals, possibly trying to get paint molds of sandstone outcroppings at Zion National Park, painted vivid blue blocks in the Kolob Terrace area of the park, spurring an investigation into who's responsible.
