The National Park Service is searching for an Oregonian who went missing in Wrangell-St. Elias National Park and hasn't been seen for nearly two weeks. 

Nick Larsen, 34, was last seen in McCarthy on August 7. Park Rangers say Larsen was planning a solo backpacking trip in the backcountry in the area.  

Larsen is described as a white male standing 6-foot-5 and weighing 190 pounds with brown hair and hazel eyes. Authorities say he has a colorful full-sleeve tattoo on his right arm. He was last seen wearing a dark green, long-sleeved shirts and black and white shorts, as shown in the picture. Larsen may be camping in a tan REI half dome 2-person tent and may be carrying a light blue REI flash day pack or 30-40L Osprey brand backpack.
