Blackall Range from Sherwell Road

entry is a road 135 m of climb chain confidence Official spatial — evidence class blackall-range--from-sherwell-road

Access verdict · Lawful, nothing to flag · weakest evidence in the chain: official spatial record

A lawful approach from Sherwell Road.

The chain below runs entirely across land the public has an established right to be on. It is a legal line, not a path: nothing here has been surveyed on the ground.

Getting to the start The trailhead coordinate, not the feature

The start is at -26.62033, 152.88036

That is Sherwell Road, where the walk below begins — 2.0 km of it. Every link here goes to that coordinate and never to the feature itself, because a driving route to a waterfall is a driving route into the country above one.

-26.62033, 152.88036

An ordinary car reaches the start The roads layer marks the road reaching this point as trafficable by an ordinary vehicle.

The coordinate is where the recorded way begins, read off the same layers as the walk. What the record says about a vehicle is above, and it describes this point rather than the drive to it. Whether the road is sealed, gated, or open today, and where a car may lawfully be left, are none of them things these records say — so treat the last few kilometres as unresearched, and the mapping service's route to them as its own work, not ours.

Every leg above is computed from cadastral geometry. Nobody has walked it, and no part of it is a path on the ground: it is the line along which the public record establishes a right to be. Where a leg names a way, that is what a managing authority has mapped down the same ground — it says nothing more about your right to be there, which the parcel already settled.

Following it on the ground Every step ends at something you can check

at least 1 hour out and back

at least half an hour there at least half an hour back

135 m up and 10 m down on the way out — so the return leg climbs 10 m.

Walking only — nothing is counted for rest, water, photographs, navigation, or the state of the track.

Naismith's rule, and what it does not account for

The way reaches this place Official spatial — evidence class

Smith Road passes 11 m from the recorded point. The gap crosses no contour, which is as level as this layer can evidence — not a survey saying the ground is flat.

Both gaps are small enough that the way is a way to this place, not merely one near it.

    Back: 172° along Smith Road, 1997 m from the start.

1997 m in total, along the way the managing authority publishes. Every step above ends at something the records let you check on the ground. Bearings are true, not magnetic: they match a phone compass with no conversion. In this part of Queensland a magnetic bezel reads about 11° east of them, so an analogue compass needs that taken off before you set it.

What each step ends at, and why Official spatial — evidence class
junction
A junction with another published way. Unmissable on the ground, and the place a wrong turn happens.
destination
The place itself, which is always where the last step ends.

A cadastral parcel boundary is never one of them. It is invisible on the ground, so a step that ended at one could never be checked — however convenient it looks in the data.

The profile is the height the contour layer already records, read along the same line the legs above describe. It is not a survey of a path: nothing here says the ground between two contours is even, and a layer of 5.0 m contours cannot evidence a step smaller than the gap between them.
