I discovered this trail not too long ago, and it has become one of my favorites. I love the geology of this canyon, and this trail gives it a great perspective. It is possible to find these caches in the snow, as there was a foot of snow when I hid some of them. However, please keep in mind that you will be skirting the side of a steep mountain, so please make sure you have approprite gear for the conditions. (If there is any snow, at least have shoe spikes and poles!) Be safe, and enjoy the hike!
For this cache, you'll need to venture up the hill a bit to the tree.
