Rationalising that at some point I'd be doing the whole Maamturks walk and wouldn't want to waste energy diverting to summits that aren't on the main route, I devised this way of tidying up the tops in the northern section. 'Twas a mucky day of mist and drizzle.
I parked at the forest entrace mentioned in the Búcán short summary, but took the Western Way south along the foot of the range. The objective was to join the ridge at Maumturkmore, but I went slightly further south along the Way, noting that there was a track marked doubling back to the foot of the stream falling from the pass. In practice this track was so manky and indistinct as to be next to no use at all, and I suspect that cutting this corner by heading straight for the pass when directly west of it wouldn't be any worse.
Anyway, once up aloft I followed the ridge somewhat arbitrarily through the mist, turning right at the top of the slope from the Col of Despondency to visit Leenaun Hill, going over the two minor tops to the north-west before crossing Búcán and making a quick descent alongside the fence to the Western Way.
