This is part of a series of 20 geocaches placed near outdoor art installations. The geocaches will only be available until mid-October. There will also be a bonus geocache for those who find all 20 in the series (look for a single letter on the logbook or container). For other geocaches in the series, see the bookmark list UCA 2017. If you see a notebook in a container attached to the sign describing the artwork, it's not the geocache logbook. Answer 4 questions onsite to get the final coordinates.
A geocacher's guide to the series is published as a google doc at https://goo.gl/4jLrRH
These coordinates take you to one of the three separate installations around Kentville which comprise Stop 16. The other two installations are indicated as waypoints below. Any one of the three installations can be used to solve the puzzle; however, this first stage of the multi-cache will put you closest to the final geocache location.
Congratulations to JordanTamara on a first-ever FTF!
Stop 16: "Subterranean-Psychic-Observatory" by Andrew Milne
Artist's description of the installation: "Playfully exploring the collision of science fiction, memory, landscape and local-history, this project reveals an imagined future history that develops in Kentville, Nova Scotia."
To obtain the final coordinates answer the following questions:
- How large is the art installation?
- A= 5 if it is about the size of a truck tire
- A= 6 if it is about the size of a smartphone
- A= 7 if it is about the size of a frisbee
- On the very top of the art installation there are several windows to show the inner workings. How many windows are there?
- B= 7 if there are 7 windows on the top
- B= 8 if there are 8 windows on the top
- B= 9 if there are 9 windows on the top
- One part of the art installation is meant to be moved in order for it to function; what direction does it move?
- C= 0 if it's a left-right motion
- C= 1 if it's a circular motion
- C= 2 if it's an up-down motion
- What colour is the art installation?
- D= 2 if it is black
- D= 3 if it is white
- D= 4 if it is grey
The geocache is hidden at N 45 04.AAB W 064 29.CDA. It is within 450m of the art installation.
