Poor GPS reception at times. At no stage do you need to disturb animal dens.
Note that there have been some incidents in this area with aggressive cows in recent years. The cache can be done as a circular walk but can also be found without crossing fields. Please use your own judgement if there are cattle in any fields, especially if they are with their calves. Also, watch out for unpleasant wild animal droppings at the final location.
You can validate your puzzle solution with certitude.
Thanks to Gowenhouse for some help with this cache.
There is a precious prize for the first to find Gollum's treasure. Congratulations to abanazar for claiming it.
