11km Circuit northern lookout

Mill Creek picnic area

This beautifully situated picnic area is located a short distance along an unsealed road, off Wisemans Ferry Rd, about 5.5km east of Wisemans Ferry. There are picnic tables, fireplaces, an information board and pit toilets. There is some excellent bush walking in the area with two signposted circuit walks starting from the end of the picnic area. There is a ‘large group’ camping area adjacent.

Hard track

From the Mill Creek picnic area (signposted on Wisemans Ferry Rd, about 6km east of Wisemans Ferry crossing), the walk crosses from the information signs to the the ‘Start/Finish’ walking track signpost at the far end of the picnic area.
Turn sharp left: From the signposts at the end of Mill Creek Picnic area, the walk crosses the picnic area to a visble handrail and steps going down to a wooden bridge. The walk crosses the bridge and bends to the left, following the bush track. After climbing gently around the hill for a while, the track climbs, steeply at times, through areas with beautiful boulder and moist forest scenery.
As the track climbs higher, it moves through drier forest and zigzags up the side of the hill. Keep an eye out for the track markers, ensuring you follow a cluster of markers up over some stepped rocks. After reaching the top of a ridge, the track swings to the left and climbs along the ridge line, passing over the small hill and down the ridge line on the other side. The track then passes a track marker on the right, keeping the large open rock platform to the left, and arrives at the junction on a small rock platform (the main track bends to the right here, going past a track marker with an old arrow nailed to the tree above it). There are minor tracks from this small rock platform to the nearby, large open platform with nice views.

11km circuit Nth Viewpoint

This informal, unfenced lookout is on a large rock platform on the northern part of the 11km Circuit, in Dharug National Park. The nice views and atmosphere make this a good spot for a break while doing the circuit walk.

Grasstrees

The beautiful Grasstree is one of the icons of the Australian bush. It is a very slow growing plant, with the trunk typically only growing about one cm per year. These plants can grow and survive for several hundred years. The trunk is usually black, apparently a result of bushfires. As with some other native plants, fires can actually promote flowering and further growth. More info.

Hard track

Turn right: From the intersection, the walk follows the ’11km Walking Track’ arrow along the bush track. The track climbs for a while, with nice views down into the gully, before dropping to a picturesque creek crossing marked with a small ‘walker arrow’. From here the track climbs steeply for a short distance, then passes another track marker at the start of a section with beautiful rock overhangs and boulders. The track then drops to another creek crossing, marked with a small walker sign on a boulder in the middle of the creek, beneath a huge tree with impressive roots draping over the rocks.
Turn right: From the creek, the walk follows the walker arrow along the bush track, going downstream and keeping the creek to the right. This section of the walk has several steep climbs and plenty of great scenery. After meandering for some time the walk passes a regenerating bush track, to the right (marked with a walker post and old arrows on the trees), and continues, crossing a gully marked with walker arrows in both directions. After crossing another gully (unmarked), the walk climbs very steeply, passing a track marker and climbing further to reach an intersection at the top of the hill (very faint bush track to the right), marked with two arrow track markers on a post.

This section of the walk has some beautiful scenery with great boulder formations and beautiful forest and valley views. It also has some very steep sections as it drops and climbs through two gullies (plus a third minor tributary) before reaching an intersection at the top of a ridge, on a small rock platform immediately after passing a track marker (the main track bends to the left here). There are minor tracks from here to a much larger rock platform nearby with some nice views.

Turn left: From the small rock platform, the walk goes west along the bush track, leaving the much larger rock platform to the right. The track soon passes a track marker on the left and gently climbs up the ridge line, over the small hill and down the ridge line on the other side. The track then bends to the right and descends steeply, zigzagging down the side of the hill. The walk passes numerous track markers along the way and eventually descends into the more shaded and moist lower part of the valley. There is beautiful scenery through this section, as the walk descends, steeply at times, then crosses a wooden bridge and climbs some steps to the edge of the Mill Creek Picnic area. From here it is a short walk across the picnic area to the visible walking track signpost.
Turn sharp right: From the ‘Start/Finish’ walking track signpost at the end of the Mill Creek picnic area, the walk crosses the picnic area to the car park (Mill Creek picnic area is signposted on Wisemans Ferry Rd, about 6km east of Wisemans Ferry crossing).

Beaufort Scale (for wind speed)

The Beaufort scale is a standard scale to communicate wind force. The scale starts at traditionally ranges from 0 to 12, with zero been no wind and 12 been a hurricane force wind of over 120km/h. The scale has since grown to 17, to describe more severe hurricane winds. For the sake of this article I have just included the 0-12. The scale include descriptions of the what to expect to see from such a force. Rear-Admiral, Sir Francis Beaufort, was born in Ireland in 1774. He entered the Royal Navy at the age of 13 and was a midshipman aboard the Aquilon. By 1800 he had risen to the rank of Commander. In the summer of 1805 Beaufort was appointed to the command of the Woolwich, a 44 gun man-of-war.

In 1806 he wrote in his log book a wind force scale. The scale was simple and very similar to one that Alexander Dalrymple had written in a book in 1789. A year later he added some criteria to the 0-12 scale that indicated how much of a ship’s sails would be employed by a British man-of-war under each condition. It was not relate to the speed of the wind.

Over the following years he continued to use his scale in his logs. It was finally adopted in December 1838 by the British Admiralty for use in all Royal Navy logbooks. However, as ship design and the introduction of steam power became widespread even that scale had to be modified.

In 1912 the International Commission for Weather Telegraphy sought some agreement on velocity equivalents for the Beaufort scale. A uniform set of equivalents was accepted in 1926 and revised slightly in 1946, extending the scale to 17 values (the added five values further refining the hurricane-force winds). By 1955, wind velocities in knots replaced Beaufort numbers on weather maps.

Today’s Beaufort Scale including the observed land conditions…

Beaufort	Wind speed		Description	Land conditions
	kt	km/h
0	0	0	Calm	Calm. Smoke rises vertically.
1	1-3	1-6	Light air	Wind motion visible in smoke.

Points of a compass (Cardinal, degree)

There are 4 basic directional indicators used; North South East and West. I assume this is not news to you. A compass uses the same principles and breaks directions down even further to allow more accurate descriptions. When needing to be very accurate you will talk in degrees when general is ok then you will talk in cardinal directions (eg when describing wind direction or the general direction of a track.)

Below you will find two diagrams and a table.

The cardinal points diagram shows a basic compass bevel and the cardinal points

The compass bevel diagram show the mix of cardinal points and degrees that are common on a compass

The Bearing and cardinal points table relates the angle in degrees to a cardinal point and the text descriptor.

Track Classification System

An Australian standard for bush track was developed in 2001 in consultation with a number of out door bodies and organisations. These Standards are used to describe the condition of the track and the terrain and give a feel for the level of experience required by people using them.

The following tables gives a bit of a feel for the tack classification standards. I have modified them a bit from the AS 2156.1-2001 to suit the need of the website. As well as these elements for classifying a track the standard does also outline guides for management, these include facilities to provide, publicity and intervention levels.

The pictures in this table act a a bit of a guide, but only refer to the specific element been studied (IE just the sign or gradient)

General	1 A well maintained path suitable for wheelchairs	2 A popular and well maintained nature trail	3 A well used and obvious bush track	4 An established bush track with limited signage	5 A marked trail that can become unclear in places	6 A known route with n signs and a very indistinct track if any

A walk is then classified based on the higest class number found.

In this table below you will see the range of assessments made for a particular track ranged the full gamut but generally sat around class 3. But because the one element of weather ranged from 1 to 4 then this walk will be ranked a 4. However if in the summer months the weather class never extends beyond 3, then you could class this was as a 3 in summer and 4 in other seasons.

Naismith’s Rule (estimate walking time)

Naismith’s rule was developed by a William Naismith in 1892 as a basic rule of thumb that can be used to calculate the time it will take to walk from point a to b. The formula has been adapted a little since then and considers the distance to walk, the altitude changed and the speed that you will walk at.

This rule assumes a reasonable level of fitness, but Tranter’s corrections can but used to change the time to suit a particular level of fitness.

Naismith’s Rule first makes a calculation based on distance over time. eg if your walking a 4km/h for 4 km it will take you one hour. Not rocket science. But it adds a bit over an hour and a half for every 1000m you climb and about three quarters of a hour for every 500 meters you descend.

I have include two methods to help you in your trip planning. Firstly a calculator and secondly a Nomogram that you can use with a ruler in the field. Have a play with both

Naismith’s Rule Calculator
Naismith’s Rule Nomogram
How to use Naismith’s Rule Nomogram

This Nomogram below can be used to calculate the estimated walking time.

Naismith’s Rule Nomogram

At first this Nomogram can be a bit overwhelming to look at. But don’t stress I think you will pick it up quickly.

First you need to pick an altitude shift line.

Move from right to left to find the line that represents the number of meters you will climb in total, next

Move down the number of meters you will descend in total.

Follow this new line up and to the left (this is your altitude shift line)

see here we plan to climb 700m and descend 1000m

Next we keep going up the altitude shift line until we get to your estimated walking speed.

This is our pivot point.

In this example it is 4km/h

Now just draw a straight line from the number of Kilometers you plan to walk, through the pivot point till you hit the Hours axis. And voila you can read the estimated time.
