The park attracted more than 4 million visitors last year and is struggling under a deferred maintenance backlog of $70 million. Four of the park’s most popular trails are closed, including the hike to Emerald Pools, and park officials were forced to close Angels Landing until Friday while a boulder in a rockfall is removed, said park spokeswoman Erin Whittaker.
Even as the centennial celebration is unfolding, park executives are reviewing a number of possible options to manage crowds and improve visitor experience.
“We know it is not sustainable what is going on right now,” Whittaker said. “We have modified shuttle schedules, but there is only so much you can stretch to adapt.”
