The images you have reproduced were likely made many — 20?, years ago. In rainforest environments, what you see from xx years past is very often not the same as what you would hope to see now. I know this from specialising in the rainforests of the Great Otway National Park. As an example, a scene I photographed in June 2013 and attempted to revisit this July is no longer extant: floods (January 2016), prolific vegetation, fallen trees and even realigned water courses made location very difficult (even with a total-track GPS record). I imagine the Tarkine's deep, cold myrtle glooms are in a constant state of change. They certainly are around the Pieman River area.
I know a few people associated with the Tarkine who could probably identify those scenes (if they made GPS waypoints, and if they took notes), but for the sake of safety they would most likely not provide information on accessibility other than what is commonly available and known (e.g. in guidebooks). I am reasonably sure the pics are on tributaries
of the Hatfield, not the river itself. My recollection is that many of these published photos were done through off-track/route walking (Savage River, Donaldson River, Huskisson River) around 1994-1995 preparatory to the book "The Tarkine" [Wilderness Society, 1995, out of print]
. Ted Mead, Rob Blakers (especially) Grant Dixon and Bob Brown were prime movers in terms of researching Tarkine scenes for that book, and the images today have an enduring, evergreen appeal. More recently, 'Tarkine Trails
' (Bob Brown Foundation) features works from the newer successful photographers in Tasmania (Nick Monk, Hillary Younger, others) along with stalwart Rob Blakers' own newer and (now quite old) images (circa 1994). RB is the type who packs his (heavy) gear for extended trips into the Tarkine, not particularly fancying short day walks or places that area relatively accessible as opposed to those which are almost impossible to find without a thorough record.
I would certainly recommend Tarkine Trails and carefully reading walks such as those to Philosophers Falls, which is an ideal introduction to the rainforest; anything more required scenically (moss-festooned myrtle et al) is most likely off-track and that's where the danger lies. Even short walks around the Savage River (and those radiating out from Corinna) can be very rewarding.
BTW,a 'taped route' does not have to resemble a track
to be navigable.
