This is quite an involved Multi - hence the difficulty rating.
According to the Barcaldine Regional Council website:
The works are located across our community and many pieces play an important role in capturing the historical values of our past. Other works portray our lifestyle, environment and landscape. They add value to our community and allow visitors to enjoy our past and present history and take home memories of their visit.
Your art-task is to go to each of the waypoints listed below, collect the information required, then nut out where the cache is to sign the log book.
Couldn't be easier than signing your name on a few brush marks on some canvas, now, could it!
WP01: A = ________ - the number of eggs that Barb Burra has.
WP02: B= ________ - first two digits of the year this art work was highly commended.
WP03: C= ________ - the number of years artist Peter Turnbull was a shearer.
WP04: D= ________ - the total number of letters in the full name of the Instructor.
WP05: E= ________ - the last two digits of the year this sculpture was the runner up.
WP06: F= ________ - the number of different types of fruit depicted in the sculpture.
WP07: G= ________ - the number of years for the celebration of schooling.
WP08: H= ________ - the last two digits of the year the shearer and sheep were delivered to the Council.
WP09: I= ________ - the number of dancing brolgas.
WP10: J= ________ - the number of letters in the plane's name.
You will find the cache at S 22° PQ.RST E 144° VW.XYZ
using the formulae (remember the rules about the order in which you have to solve maths puzzles!):
P = D * J - (B + C)
Q = A * D - B
R = C * J - G - H
S = E - ((G + I) / H)
T = (E + D) / I - H
and
V = E * J - A squared * A squared
W = (C + A) / E
X = ((J * H) - (A * B))) / I
Y = ((H + I) * A) - Jsquared
Z = (I * E) - (H * I)
(Checksum = 35)
Answer: S 22° ________________ E 144° ________________
BTW, this is not a list of ALL the artwork around Muttaburra - feel free to find and enjoy the others. Some you might see or pass when completing some of my other geocaches in Muttaburra.
