Mungo Pass

From Brunswick Creek travel up to the pass is mostly on gravel.
On the Gibson Stream side, head down from the pass on steep snow-grass into the basin at the head of the valley. South-west of Pt 1290m Gibson Stream is gorged, with a waterfall at one point, so either climb out immediately on the true left up to a shingle bench at the 1440m contour (and then follow the spur beyond that down to the col immediately north of Pt 1290m), or descend Gibson Stream a short distance before climbing up to the same col.
From the col north of Pt 1290m sidle across to the true left of the first creek marked on map sheets J34 and BV19 east of Pt 1290m and descend to Gibson Stream itself before the second marked creek. In spring – sometimes into summer – avalanche debris may fill the gorge, allowing an easy alternative route down on snow, but remember that there is a waterfall under the snow somewhere.
