Redstone Cyclery has been the designated trail steward of Heil Ranches Picture Rock trail since it's inception. Any time we'd have a trail work day set aside, County staff would ask us what we wanted to work on, we would figure out a place, and we'd get a crew out there to get 'er done. About 8 months after the trail opened, it was obvious that the very first uphill right corner (and the very last downhill left hander) was built wrong. Going up was no big deal, but coming down was a decreasing radius off camber corner. In short, it was a corner designed to spit people off trail. After a few years, the corner got more blown out with more braking bumps and just plain got worse. We kept bugging Boulder County to let us rebuild the corner. Always, the answer was, "No, that's too big of a project." We kept plugging away with other trailwork sessions and continued to build our relationship with Boulder County Open Space. Finally, when we sat down to schedule a winter Saturday for trailwork, we once again asked about this corner. Finally, we had our chance.
You can see in the picture above where the new line crosses the old line. Coming downhill, we made a slight dip to the left, then back up to the right. This is both to help scrub trail user speed and to help shed water from the trail.
Here, you can see the finished berm. LOTS of road base material was brought in. The road base is a better material for compaction. It takes over a year, but it sets up and hardens better over time than regular dirt. More road base, smoothing, raking, more road base, smoothing, raking, etc. We kept working and reworking this corner until it made sense.
After we ran the compacter on the newly benched in trail, we took some more material off the upslope side to create a back slope. By this time, the tread of the trail was great, but having what is effectively a curb on the right can potentially catch a riders wheel or pedal. We got on that chain gang style and had the back slope dialed in within minutes. What a great working crew we had today!
Below is a shot of our newly bermed and compacted corner, looking at it as if you were coming up the trail.
