We find all sorts of curious things along the trails, streets, and creeks. Here is an unknown cache to share one curiosity we often stumble across, sometimes literally if our noses are pasted to the GPS arrow.
We hope the tools you discover and use to find this cache attract some interest to these odd spots around here. Also, perhaps someone can answer a question: exactly who is behind the vast Vertical Control Network?
[Note- Certitude will give credit for approximate coordinates. Depending on how you solve this your numbers may differ slightly from ours. You may not need even need a verification tool.]
Update 7/9/2022 The original location is in a construction area, and the work is supposed to continue until November, 2022. The cache location was moved a short distance. Enter the original location solution into Certitude and the new coordinates and an updated hint will be provided.
Update 8/15/2020 The most usable resource for determining the coordinates is still available, though is is a bit fussy about browser choice. On laptop or desktop computers Google Chrome with javascript enabled will work, Firefox is giving us problems.
Congratulations to lmt000 for FTF
