Russell Corfman posted the route:
The Black Canyon National Recreation Trail, or BCT, is a ~75 mile trail running North to South from the Prescott National Forest Boundary to the Carefree Highway. The trail is a multi-use pathway for hikers, cyclists, and equestrians. The trail follows ancient Indian pathways, Sheep herding migration paths, and stage coach routes. The trail was designated as a National Recreation Trail in 2008. There are two loops along the trail, so travelling end to end is about 75 miles.
As far as I can tell, the northern end of the trail is at the Prescott National Forest Boundary at the section corner above Russian Well and past Tri-Metal mine. The coordinates on the road near the boundary marker are N34° 27.505' W112° 08.701'. There are BCT trail signs north of there, but I was told that there is no multi-agency agreement that extends the trail into PNF. I have seen BCT trail signs in other areas away from the trail too, so it's a mystery.
There are no trail markings for the last mile and a quarter or so on the southern end of the trail. I used a trail map on the BCT Coalition web site and followed it as best I could, finding old flagging on brush and what appeared to be trail. I wasn't able to discern where the trail actually ends so I am extending it to the gate at N33° 47.886' W112° 11.024'.
My hope, for adding the BCT here, is to give it some more recognition.
More information on the BCT:
Dec 31 2019 I’ll be going north to south on the BCT self supported to try and best Russell’s time. I’ll have a SPOT link on my Instagram @derricklytle and will also track via my Coros watch to post to Strava later. I’ll use the northern GPS and southern coordinates posted above as official start and stop points. Excited to see this entire trail!
And completed the BCT in 34:19:22 solo self supported.
February 26, 2020 I'll be hiking southbound unsupported with the intention of spending one night on the trail and finishing late on the night of 2/27 or early 2/28. I'm hoping that the recent rain will provide adequate water, but will be carrying around 5.5L of bottled water just in case. This will be my first time on the BCT, so I'm treating this as a scouting hike for future goals. My plan is to get dropped at/near the Northern coordinate around 9AM (I will be leaving a car near the end of the trail).
I'll be tracking with my inReach mini at https://us0-share.inreach.garmin.com/poet
If I remember and have service I will be posting photos to my Instagram @poetac
I will post my data to Strava and give an update here later this week.
I learned a ton on my attempt, but due to a foot injury decided to cut it short at Table Mesa Trailhead.
I found the trail to be a beautiful sampling of desert terrain, and will certainly return in the future. If anyone wants more information feel free to DM me on Instagram. I will be posting my data to Strava sometime soon.
