It's something Utahns have witnessed in their own backyard for years now, as more and more people flock to the state's national parks.
And it's something the U.S. Senate held a hearing on this week for one of the first times as more summer visitation numbers exceed expectations.
It's overtourism — when more than a manageable amount of visitors come to a park and all that entails from environmental to economic impacts.
The Senate Committee on Energy and Natural Resources, where Utah Sen. Mike Lee (R-UT) sits, held a "hearing to review the impacts of overcrowding in our national parks on park resources and visitor use management" on Wednesday.
