This traverse, taking in the Maud Francis and Avalanche Glaciers and Rob Roy Stream is a way of walking out from climbing in the Mt Aspiring region and avoiding the walk down the Matukituki Valley. From the Bonar descend the Flightdeck and traverse around the Maud Francis and cross the ridge between Mt Avalanche and Rob Roy near the middle. Then continue down and around the Avalanche Glacier and link up with the snow shelf which runs underneath the East Ridge of Rob Roy. Use the access route for the head of Rob Roy Stream in reverse from the Rob Roy-Homestead col. The Avalanche Glacier may be a tangle of decomposed ice near the end of the summer and require more time than advised. Usual times are: Bonar to Homestead Col, 6–8 hours and Homestead Col to carpark, 4–5 hours.
