Welcome to the ‘Australian Coat of Arms’ Geo-Art. This will be released in stages. This stage is the Shield. Each puzzle is different and is ‘hopefully’ designed to help you learn a little about different types of puzzles. Some will obviously be a little harder than others but should be doable with a little patience. You will find plenty of puzzle solving tools in your toolbox.
The cache is NOT at the published co-ordinates.
Brisbane Valley Rail Trail.
The Brisbane Valley Rail Trail, when completed, will be a 160+km recreation trail from Wulkuraka to Yarraman. (two small sections are currently not complete, funding has been made available to complete these sections.) It will follow the old Brisbane Valley railway line and provide walkers, mountain bikers, touring cyclists and horse riders with an opportunity to experience the history and landscape of the Brisbane Valley.
The trail is for walking, cycling and horse riding only. The trail surface is gravel and unsuitable for road bicycles or personal mobility vehicles. NO motorised vehicles of any type are allowed.
Allow 1 hour plus if you are doing just the shield caches and a full day if doing the complete series on a MTB, longer if walking.
As with any outdoor walk, take plenty of water as there is NO water along the BVRT, (only in the towns nearby, ESK) and sun protection as it can be very hot along the BVRT with some sections having very few trees to hide under.
MAGPIE ALERT
Also note that MAGPIE season is September through to November and magpies do nest along parts of the route. So take care.
The Puzzle.
You will need to solve the below puzzle to work out the location of the cache itself.
The Spark Sudoku is a sudoku in a shape of star. This is the Super Spark Sudoku where the points has 36 cells. Like as Sudoku, the goal is to place the numbers from 1 to 12 in each region, row and column. The particularity is that each row and column is spread on two points of the star. There are 3 regions in each point as shown with the heavier outline
To work out starting locations to read the 'grid' I will use numbers 1-7 (outside the brackets) to indication the correct point. 1 will be the topmost point and then go clockwise from there. Use the yellow square to count out the column and row number.
1(C4 R4 ) 2(C1 R6 ) 3(C6 R3 ) 4(C2 R6 ) 5(C4 R4 ) 6(C2 R2 ) 7(C1 R5 ) 1(C5 R4 ) 2(C5 R3 ) 3(C3 R5 ) 4(C6 R1 ) 5(C3 R3) 6(C3 R2) 7(C2 R5) 1(C5 R6)
