From Lossihytta head north-west over the plateau (late in the season there can be a lot of water under the snow - take care!) until you reach the slopes that lead up to a broad ridge. Climb up following the left-most of three visible bowls. Once up on the ridge, follow it north. The triangle-shaped south face of Rienatcohkka is visible straight ahead, to the north-northwest the west summit (1871 metres) of Storsteinsfjellet comes into view. At 1150 metres you start on the steeper slopes of Rienatcohkka. Its best to stay on the left side (west) of the face, near the south-west ridge. The face is 35 degrees and gets slightly steeper near the top - you may need to take your skis off here and boot pack. To descend, you have two options: 1) Descend the same way. The face is a fantastic run! As it gets flatter, skirt the slopes to the right to get through the flats. Some pushing is required on the ridge, but then a fun descent takes you back to Lossihytta. 2) After the steep summit slope, keep right and turn right into a fun little slope down towards Lossivatnet (30-35 degrees steep). Return to Lossistua along the lake shore. Be mindful of the water and weak shore ice.
