Perfect 7 - Geoart
There are 7 geocaches in the Perfect 7 Geoart each with a different type of puzzle. The Geoart is in the shape of the number 7. All caches in this series are bison tubes hidden 6-8 feet above the water and can not be accessed from land. You will either need to float or wade to each of the caches.
Perfect 7 - I had a Revelation
There is something common about these 7 items. Some will see it right away. Take note of the numbers that would follow the numbers in the brackets.
A = 7 Mountains (17)
B = 7 Stars (2)
C = 7 Eyes (5)
D = 7 Lamps (4)
E = 7 Heads (13)
F = 7 Bowls (21)
G = 7 Thousand (11)
The cache can be found at:
N43 3 [A-B] . [F-E] [G-D] [F-A]
W79 5 [E] . [B+C] [D] [D]
This one you could probably kayak/canoe too if you carry your kayak to the nearby launch point. Tubing is also a good option. If you decide to wade through the water, please be careful as the silt that has accumulated on the floor can be knee deep, especially near the nearby launch point.
