Helena, MT -

The most recent search for a missing Denver man whose pickup was found at a trailhead northeast of Helena last month didn't reveal any new clues.

Lewis and Clark County Sheriff Leo Dutton tells the Independent Record the search on Saturday failed to find Dale Brownlow.

Searchers spent three days in mid-December looking for Brownlow in an area where his vehicle had been parked for two weeks.

Dutton says weather conditions will likely prevent additional searching this month.

Authorities say Brownlow had been living at a hotel in Helena for at least a month before traveling to the Hunter's Gulch area leading into the Helena National Forest.

He was last seen on Nov. 28.
