Concerns over visitor safety have prompted officials at Yellowstone National Park to temporarily close a popular viewpoint at the Grand Canyon of the Yellowstone. Spokesman Al Nash says the last two tiers of concrete stairs leading to the viewing platform at Inspiration Point have been temporarily closed due to severe deterioration of the steps. Nash says, “When you think of the Canyon area and realize that during the winter, we’re going to see snow measured in feet and temperatures that at times will range down to 40-below-zero, and then summertime with heat and temperatures that can reach 90-degrees, it’s really hard on all types of infrastructure.” He says as a result, there has been some very severe deterioration of the concrete steps leading to and the platform itself at Inspiration Point. At this time, Nash says it is unknown how long the viewpoint will be closed as the damage and the funds needed for repair it are still being assessed. At this point, he says, “we know we have a problem – we have to figure out how we’re going to repair it; and that’s the current hurdle.” In the meantime, the variety of other viewpoints surrounding the Grand Canyon and the Upper and Lower Falls are still available to the visiting public.
