This is perhaps the least technical route on Mt Arrowsmith. Most parties reach the head of Moses Creek via Moses Rock, a domed bluff sitting on the true left of the creek. Moses Rock can be reached from the Lawrence Valley via various routes, but most commonly by following a scree gully immediately south of a patch of scrub about 1250 metres south of the creek draining the south side of Moses Rock. Aim for Pt 1646 metres, then traverse north to the flat plateau above Moses Rock. From here, climb the glacier at the head of Moses Creek. The upper section of glacier can be reached by either a steep snow ramp (a rock step with rock fall late in the season) or by climbing to a small col on the ridge south-east of Pt 2319 metres. Once at the col, drop northwards over the ridge to sidle around the steep, lower part of the ridge, then head eastwards onto the crest of the rock ridge and from here gain the upper glacier. The upper glacier provides access to various gullies and loose rock ribs which lead to the North and South ridges of Arrowsmith. Follow the ridge (exposed in places) for the final few metres to the summit.
