NOTE: the coordinates are the closest coordinates we were able to get from our GPS due to the gorge walls, and are not the actual coordinates of the cache. You'll have to follow the instructions below to find the cache.
The cache is at the bottom of the gorge, so you may have poor GPS reception. You'll have the best luck with the GPS if you are standing in the middle of the river. Don't be afraid to get your feet wet. The river is fairly shallow in the summer, but watch your step.
Go down the stairs to the bottom of the gorge. It may be slippery between the bottom of the stairs and the river. When you reach the river, head upstream, and go under the David St. bridge. At the bridge, a large section of the West cliff face (on your left if you are facing upstream) is exposed. Shortly after the bridge, you may be able to see a fire pit on the East bank (on your right if you are facing upstream). Keep going. There will be a smaller exposed section of the West cliff face, and then an exposed section of the East cliff face. The cache is hidden in a crack in the East cliff face.
If the river bends to the East, you've gone too far.
WARNING: The river can be very fast moving during the spring and after heavy rainfalls. Do not enter the water during these times! The cache can be found during the winter provided the river is fully frozen or if you stay on the bank; however stick to the edges and avoid thin ice.
