Built in the winter of 1957 by NZFS staff Jock Fisher & Merv O'Reilly after NZFS took over the wild animal control from the Dept. of Internal Affairs. The original flat iron roof leaked & it was replaced with corrugated iron. This was the first NZFS B49, two-man bivvy built in Westland, & probably New Zealand, so it is of some historic significance. Rob Brown reports it is now the only remaining biv with the steep pitch roof & small window left on it's original site from that era. Rob reports that after this the NZFS standardised the crawl in biv design. Rob reports the only other hut of this design is 'Pinnacle Biv', which was moved there from the Crawford valley, & renovated by DOC a few years back. Edit Hut
