From Marcel Col

From Marcel Col, the route is straightforward on moderate snow slopes, although hard ice can form easily here, especially in winter. You’ll also find good evidence of climate change here: a large gap is starting to form about halfway up the ridge and soon we may see exposed rock, which will make this route more difficult. A sad sign of the times.
This is the most common way to access Engineer Col and the North Shoulder of Tasman. It’s also the recommended descent route, but beware of the cornice that sometimes form on the summit of Lendenfeld.
