Here are some pictures of rock work and armoring from the last couple weeks here in Arizona. What do you think?





This one was over a two foot step that users were going around.



And some checks

nice

around here, we use rock armoring to harden up squishy spots, there's big rock pitched together underneath the gravel dust topping that is used to lock it all in.

first picture was right after we finished this little spot, so now the rock is actually more visible (2nd pic is a few weeks later)

Whomever did this work knew what the heck they were doing:thumbsup:

Of course a before pic would have shown the sloppy mud and multiple roots that had become quite a hazard. So this work protected the roots as well.

Time lapse video of some trail armoring at Lake Fairfax in Reston, VA...

This particular spot has been trouble for at least 5 years. Recent home construction just to the right of the video has made it worse - lots of water run-off, making the mud pit permanent and deeper (park land manager is in talks with construction company to re-engineer their drainage).

This trail is part of a wide, multi-user trail network in a dense suburb of DC. Lots of hikers, dog walkers, serious mountain bikers, recreation cyclists on hybrids, and the occasional equestrian. As such, drainage problems quickly become major problems, as trail users ride/walk around the mud, which tends to make the problem worse.

Rock armoring

Nice work, its always good to utilize durable rocks for tread surfacing if they can be found nearby. I've ridden a lot of those Sedona trails, great work you guys do.

We've been doing a lot of Griphoist/rigging work for moving BFRs into place as smaller ones tend to get moved around or kicked loose unless locked into place between immovable objects.

This was a short reroute in Hatcher Pass, AK, you can see traces of the old trail on right. We utilized a large flat rock that we uncovered in the foreground and added to that with a rock slab culvert over a small stream and fitted rocks to form a causeway over the talus chunks. It was a lot of work but worth it, I think. Three years later, it's still holding up great.

Do you have any pictures of mountain bikers riding up your rock ramp?

TD
Actually, that's perfectly level ground with a lake in the background - there's no ramp. The ground was trenched out and large pieces of shale were fitted in at approximately a 45-degree angle in the trench giving sort of an optical illusion that there's a ramp in the picture. Does makes for an amazingly tight, strong armoring that still allows water to move through underneath. Riding over it absolutely nothing shifts, unlike regular lay-it-flat on or just into the soil surface stuff.

I actually helped build it (was fooling around posting earlier). It took like 7-8 guys most of a Sunday hauling a lot of rock to build but its worth it since its a once-and-done forever deal.
