This is the old road that takes you to the trailhead that will take you to the summit of Mount Mark. Here is a nice spot to catch your breath and take in the first of the views of Horne Lake. The trail is not for the faint of heart. If you plan to go all the way to the summit, plan for a very big day! Carry lots of water, and be prepared for a very steep trail!
Cache is a lock n lock hidden on the right hand side of the road, when you're heading up the road, tucked in behind the base of a small tree.
Have a great adventure and enjoy the views!
