One of Arizona’s popular tourist attractions, Casa Grande Ruins National Monument, is dealing with a stinky problem.
The monument’s picnic area will be closed through April 30 due to an invasive and foul-smelling weed, called stinknet, that has overtaken the area, according to The Associated Press.
Stinknet, per the outlet, “has a turpentine-like odor and can cause serious breathing problems as well as severe skin rashes.”
Monument officials are asking visitors not to walk near — or step on — the flowering weed to avoid spreading it.
