Just a FYI on what we're doing with Ridgeback these days.  As the Moose Mountain area is full of seeps and an apparently high water table [they don't call it Sulphur Springs for nothing], soggy spots appear on the trail that don't always come up when we do the initial build.  In some cases we can reroute the trail, but that's not always practical or possible.  In the case of R4 [the northernmost section of Ridgeback], we are blessed with an abundance of rock to fill in some gushy sections of trail.  Using rock is a common practice on trails around the world, but isn't used that often in the Calgary area. 

To be honest, this is a bit of an experiment.  Past attempts at armouring the trail haven't always worked quite the way we wanted them to.  We'd like to hear your feedback on the success of the rock placement.  Bear in mind that the purpose of this is to provide an alternative to riding muddy trail.  If you ride over the rocks and don't fall in the mud, I'd call that a win.

Note: all rock was gathered from sites directly adjacent to the trail, and hauled by hand or by wheelbarrow [now broken] and placed by hand.
