The International System of Units (SI), commonly known as the metric system, is the international standard for measurement. The SI plays an essential role in international commerce and is commonly used in scientific and technological research and development. This cache is part of the SI geoart that allows you to learn about the SI units. Visit the introduction cache to learn more about this geoart.
Learning SI Comes with Prizes
Since the publication of SI geoart, many have been learning about the International System of Units. As of this writing, there are 250 correct solutions among sixteen mystery caches.
You are eligible for a prize if you have solved at least fourteen (14) puzzles in this series. The verb is "solve", which means you don't have to have found the baby-nanos.
Each prize is a signed postcard. There are five prizes located in this container. Grab a postcard only if you have met the requirement.
This Geocache
This cache is located at formerly Percheron Perch. I was the Last-To-Find on that cache. After that find, I walked toward Shady Grove station and hid the baby-nanos along the way. Therefore, this cache marks the northern boundary of "SI series territory", while foreword is the southern boundary.
Trails are open daylight hours only. You can claim this cache once you've reached the waypoint and signed the logbook. Please ensure the cache is covered by rocks before you leave, so that ManBear does not move it ;;;;;;
FTF gets an unactivated trackable, which I found somewhere along GR&C trail. Postcards are only for those eligible. Other trade items follow the normal "take something, leave something" rule.
Question: what's the distance, in metres, between the northern and southern boundaries of SI series? Round it to an integer and enter in Certitude to unlock a photo.
You can validate your puzzle solution with certitude.
