We have a new trail map system for both hikers and EMS.  There are now QR codes on the signs and if you have a smart phone on you and QR app you can scan it and it pulls up a map of where you are on the trail.  The NEW trail markers help you know how far you are on the trail and how much further you have to hike.  It also has a RED letter and number in the upper right corner if calling 911 on the trail give them this number so they can find you faster.
