Not sure Adam. I think the best option is taking the decisions the day of, after having assessed the terrain. It's not a bad idea to brain storm at this point but it's so hard to evaluate what needs to be done when we're not on site. Bolting rods into the granite slab might be an option IMO.
I think in the future (when Ascent is no longer in the embryo stage) this would be a great project that Ascent NB could decide and vote on and ultimately delegate the work to a special committee (trail crew) for cleaning day.
