The man had reportedly been yelling incoherently at the bushes and shooting a handgun, Michaelis said.
Sheriff's deputies were called at Pictograph Cave around 1 p.m. on Tuesday.

Officers approached him and were able to apprehend him without incident, Michaelis said.
Pictograph Cave will be closed for the rest of the day, according to Jarret Kostrba, manager at Pictograph Cave State Park.
