From Dynamo Red hut, cross back over the creek to flats on the south bank, and follow the faint trail up WSW up the spur to the water race at the corner of the valley. The poled route then follow the water race to the main creek, head 100m up the creek and then zigzags up onto the spur on the western bank. From here a poled route leads to Aurum Basin Hut (Archie's Hut). Poling in intermittent but just-about followable over open grass and tussock.

Note: Described in the reverse direction to your journey

From Aurum Basin Hut (Archie's Hut) a track poled with plastic road markers leads south and down the spur towards Dynamo Flat. Dropping off the spur the track descends to the creek, which it follows for 100m to the start of the water race shown on topomaps. After 300m or so it cuts east off the water race, descending a gentle spur to Dynamo Flat - visible below.

A 'bulge' of beech forest juts out into the flat. Follow the bushedge and at the centre of the 'bulge' you'll spot an old, worn pack-track is visible descending to the creek below. The track is getting overgrown and is not signposted, but crosses the creek and climbs to Dynamo Red Hut in the clearing on the opposite bank. A dry-footed hop across the creek is possible, but it can become impassable after rain. A 2-wire 'bridge' of fencing wire stapled to trees does not look to be a particularly safe alternative crossing for high water conditions.
