Nice to see a report on these two... Not hugely popular pair of Corbetts, but I'm sentimental about them. Been up there 3 times, the first time we had to retreat before even reaching the first summit due to torrential rain... The second time was in full-on winter conditions. Kevin forgot to put a tea bag in the flask, so we drank water on the top of Meallan
It was so cold that we didn't care what sort of liquid it was, as long as it was hot
Maybe this winter we'll visit them again!
BTW, you found the summit of Sgurr a Mhuilinn
, the cairn is the very top (though in cloud it may not look like it). The trig point has fallen apart and whatever is left of it it is buried inside the summit cairn.
