The most prominent part of the glacier is on the northwestern side of the valley on the slopes below the 2,644 metres (8,675 ft) tall Rob Roy Peak.

[1] This part of the glacier extends from just below Rob Roy Peak down to a bench high on the valley's side where it abruptly breaks over the cliff's edge at around 1,500 metres (4,900 ft).

The spring melt causes frequent small avalanches, and seracs breaking off the glacier's terminal face on the northwestern side of the valley.

[7] Avalanches and ice blocks breaking off the glacier's terminal face are a regular sight in spring, and kea can often be heard and seen flying above.

[3] A regular shuttle service for trampers is also available, as Raspberry Creek shelter is also the start of longer hiking trails into Mount Aspiring National Park.
