Tri-Cities 2022 Geocoin Challenge
Bonus Cache
Now that you have explored the Tri-Cities and that the map has no more secrets to you, time to use your coin to find the bonus cache! The cache is at the posted coordinates but you will need a 3-digit combination to open it.
Using only the 4 bridges highlighted on the coin and taking the shortest path, solve for the three digits using the following clues:
- The Duportail Bridge is worth 1
- The Blue Bridge is worth 2
- The Cable Bridge is worth 3
- The Railroad Bridge is worth 4
- Add each bridge's value as you cross it.
Here is how to obtain the three digit combination:
- For the first digit of the combination: go from Finley to Burbank.
- For the second digit of the combination: go from Richland to West Richland.
- For the third digit of the combination: go from Downtown Richland to West Pasco via Kennewick.
