This cache is not for everyone and it is very possible you will get to the GZ and decided you will have to let this one go. Neither I nor geocaching.com are liable for any injuries that may result from an unprepared pursuit of this cache! Please only attempt to retrieve the Cache if you feel physically up for the challenge. (shamelessly taken from hrc333)
This is the tenth cache of the SF Geocachers "12 Days of Cache-mas" series. 12 caches were released one per day from December 13-24, 2015. Each cache in the series provides a code that will help you find a final puzzle cache.
Lord Byron's green Cache-mas ornament (bison tube to you cachers out there) leapt about 9 feet in to a tree. It's well camouflaged among the leaves. Can you find it?
Congratulations to TomLovesBacon for the FTF!!
