From Ariels Tarns. Drop northwest down gullies into the stream and cross it, ascending the scree above onto a shoulder of the northeast ridge running to the 1809m point. Continuing on up the NE ridge, the first major obstacle is soon encountered where the ridge narrows to a pinch and is intersected by the vertical fault scrap. The resulting deep notch in the ridge is approx 2m wide, exposed and must be carefully navigated.
The final third of the NE ridge feature a couple of gendarmes that can be turned on the Whitehorn Pass side.
Once point 2059m is reached, drop onto Cronin Glacier to avoid the initial section of rocky obstacles before regaining the meandering SE ridge of Rosamond and following it to the summit. This involves making your way up through a very loose rock step halfway along the SE ridge.
Notes: Avalanches sweep the Whitehorn Pass and ice-field area in Winter/Spring. The notch on the ridge is very difficult to climb through, consider your options, and don't fall!
