When I first arrived in Colorado, I was looking for a good place to hide a cache.
Imagine my amusement when I discovered a mountain top of my own. 
I knew I had to put a cache there. Two years later, I’ve finally completed that quest!
Yep! It's a 5/5.
5T -- If you take the North route, for whatever reason, you're gonnna need equipment.
You can go up the South face for a much easier climb, no equipment necessary.
5D -- It's a flippin' NANO... on a mountain top... concealed within a 'SKuLL Rock' !!! 
Once near GZ, there will be no technical climbing required to get to the cache.
In other words, it's not on top of those rocks.

SKuLL Rock
SKuLL Rock is a 7,126 ft mountain peak near Deckers, Colorado.
It's just West of South Platte River at the intersection of Hwy67 and Hwy126.
It ranks as the 3,768th highest mountain in Colorado and the 13,424th highest mountain in the United States.
Congrats to ernie66 and estes01 for their co-FTF!!
