Hey, where the heck did you see that cactus? That moss looks a lot like the kind on the hills in my backyard in Hurley, right around where I've been working on a steep sketchy catwalk section that gets you up top. I've unfortunately had some problems with sections washing out though and have been looking into building some sort of retaining wall with rock, but thought that erosion prevention would be a more permanent solution and cactus would certainly grow well in this spot..
Also, are there any decent trails (read: singletrack) worth exploring on Overlook? I've only been up and down that bruising fireroad on foot and although it seems like there are some off-shoots up towards the top, I really would love to find a singletrack version that would climb up or around the way the fireroad winds up.
