(Portland, OR)  --  A Portland man is among four mountain climbers stranded on Mount Rainier.  Park officials say Yevgeniey Krasnitskiy and his fellow climbers became stranded on the difficult Liberty Ridge route Monday afternoon after losing their climbing equipment and tent to high winds.  Poor weather conditions hampered rescue crews yesterday in their efforts to reach the climbers.  Crews are expected to try again today to rescue the group.
