    Lower Rocky Canyon

    		Mt Mac was groomed with the Elan + drag/groomer. I’d expect the trails to be quite good!!! - Lower Rocky Canyon (2 passes) - Lichen It (2 passes) - Aspen For it (3 passes) - Amanda’s (likely requires lower tire pressure) - Bouncing Bunny (Amanda’s to TBT) - Two Burnt Trees - Fetish (2 passes) - Upper Rocky Canyon (2 passes) - Birch - The Collective - CanCan - Porcupine Ridge (CanCan to 24HoL Connector) - 24HoL Connector (3 passes) - Powerline & KSA/TCC (to 24 HoL/Rebirth) - Rebirth (likely requires lower tire pressure) - Calypso Canyon (likely requires lower tire pressure) - Reimer Reason (likely requires lower tire pressure) An enjoyable Big Loop via Rebirth-Calypso-Reimer should be possible (w/ lower tire pressure), but check the Nordic Ski Centre website for trail closures on Saturday as the XC Ski Marathon is happening. A modified Big Loop via War Eagle Way is also possible; Bouncing Bunny from Raven’s Ridge has seen plenty of foot traffic to connect into the grooming on Two Burnt Trees or Amanda’s.

    		Not recommended. Looks like Elan packed in the last 4 or 5 days, but several trail runners and dog walkers ventured forth before it set up. Pretty soft and pitted with running tracks. Needs another and packing and 24 hours to setups

    		Trail groomed with snow dog by CMBC. Trail rideable but not as packed as some of the other Mt. Mac trails. 24hrs trail section from the Power Line to the Trans Canada Trail is also groomed.
