(Portland, OR)  --  Officials say all 12 hikers who had been reported missing near Multnomah Falls are said to be doing fine.  The hikers, all from Texas, included one who fell in a hole after the group hit an unsteady snowfall yesterday in the Columbia River Gorge.  No one was injured.  The Multnomah County Sheriff's Office says the trail was extremely slick because of warmer-than-usual weather.
