A man visiting Yosemite National Park has gone missing, officials said Tuesday.

Hayden T. Klemenok was in the park and entered Chilnualna Creek near the trail junction about 2 p.m. Sunday while hiking with friends and his whereabouts were not known Tuesday, park officials said on Facebook.

Officials said they are looking for information from anyone who may have seen him or have been hiking off-trail in the area of Upper Chilnualna Falls on or since Sunday.

“Simply knowing where you went and when you were there may help us focus the search, whether you saw anyone or not,” officials said.

Klemenok was wearing a tan brimmed hat, white sunglasses, red T-shirt, blue swimming trunks and white Adidas shoes, according to the news release.
