A signed junction with Oliver's Loop
identifies Q as continuing to the right. This trail includes some faster cruising, across a long bridge over a wet area (slippery when wet), then it pops out on a wider ski trail to climb to the ridge. The top of the ridge goes to tight trail again as it climbs and drops down steep black diamond rock ledges - the last one is the biggest drop.
It's a tough climb up from the beaver pond to nice poplar forest climbing to bring you back to the ski trail and re-connect with Oliver's to complete the loop. All marked with the Orange arrows as is Oliver's.
