In 2019 there were just a few Adventure Labs in the Denver area. I received a credit and created my first AL - The Parks of Greenwood Village adventure lab. The lab is still going strong, but the previous bonus cache, GC8H241 was lost when the stump it was in was removed.
I have finally gotten around to putting out a new final. If you have completed the Adventure, you don't need to do it again. I have updated the Aventure information to reflect this new final, with updated information when you complete each stage. There is a checker below to ensure you have the correct new coordinates. If you enter the old final coords, you'll get the correct coords for this new one.
The Marjorie Perry Nature Preserve is a hidden
treasure tucked away in the heart of rural Greenwood Village. It is surrounded by one of Colorado’s premier trail networks, the High Line Canal. This natural area provides an opportunity for park and trail users to free their mind and spirit amongst the backdrop of scenic landscapes of natural vegetation, wildlife habitat, and drainage ways. The Marjorie Perry Nature Preserve is the perfect location for artists and photography buffs to capture nature’s beauty.
This seemed like the perfect place to have the finale of the The Parks of Greenwood Village Adventure Lab finale. This Adventure Lab can be found here - https://labs.geocaching.com/goto/GWVPARKS
Complete the Adventure Lab and at each of the 5 stops you'll find a clue to where this final is. And then enjoy another gem of a park in Greenwood Village!
The Final is located at:
N 39 37.1PA W 104 55.RKS
The D/T of this multi is based on the combination of the Adventure Lab stops and the setup of the final. Please replace everything EXACTLY as you found it to preserve the experience for the next finder.
Posted coordinates ARE a good place to park.
