I will be hiking the AZT around Flagstaff this summer, and I am planning on meeting my wife (trail angel extraordinaire!) where the trail crosses or comes near to highways or trailheads. But, if I get there before she does, I'd like an LNT method of leaving her a signal that I've been there and gone on, so she won't wait for me.
For example, if she drops me off at the Marshall Lake Trailhead (AZT # 31 Walnut Canyon), and I hike north, I'm thinking she could drive to Canyon Vista campground, and hike the two(?) miles to where the Sandy Canyon trail intersects with the AZT. But, if I get there before she does, I don't want to have to wait for her to arrive. And, if I've already gone, I don't want her to sit and wait for me. Understand?
Any ideas? A long strip of cloth tied to a nearby branch? A pile of empty Bud Light cans in the middle of the trail?
A "special" gouge in the trail with the heel of my boot?
Any LNT ideas would be appreciated. Thanks.
