Sort of encountered some thermal features today.
On the Mt.Tangariro Alpine Crossing, one comes across the Ketehani Hot Springs off to the side. This area, which is a privately owned inholding in the national park, has been closed for the last decade or so. It was getting too much abuse by hot potters and other Nature Lovers that the owning Maori tribe said "no more." Now there are barriers on the former trails to the site.
Over the years there have been reports of at least one geyser there, if not several. Now all you can see is thick steam coming up from behind the ridge hiding the hot springs gully.
