Welcome to enjoyable Banner Forest. Park at the parking lot (coordinates provided below) and take the main trail. Follow the main trail to the suggested Pr 1 trailhead. Follow trail Pr 1 to the Mish Mash trailhead. The cache is located just off the Mish Mash trail.
You are looking for a camouflaged Lock n Lock about 6 feet off the SE side of the trail. Due to the heavy tree cover, my reception was not the best. Keep this in mind while you are searching. Please be kind to the area and replace the cache making sure it is tucked back in. The fifty cent piece is for the FTF.
After you find the cache you can continue to explore and enjoy Banner Forest and its extensive trail system which we highly recommend. A good source for many of the trails in Banner Forest can be found in Northwest Trails at http://www.switchbacks.com/nwtrails/
