Ambrose Saddle

Ambrose Saddle can be reached via a long traverse from the unnamed stream east of Prelude Peak.
From the saddle move west until a route can be found down the small glacier below the col, then
traverse to the south ridge of Pt 1883 metres and follow this to the Lawrence Valley floor, making sure
to avoid Hells Gates. Alternatively, from the saddle traverse Pt 2106 metres to join the south ridge of
Pt 1883 metres.
