This article also appears in the book 'It's a Fine Day for the Hill' by Adam Watson (http://tinyurl.com/ay4n9o4), which is strongly recommended, especially if you have an interest in the Cairngorm mountains.
In reply to Douglas Griffin: Thanks, I'd read the article in the SMCJ but that didn't have the photos. And I must order a copy of the book - I prefer to buy from bookshops but none of the shops I tried last time in Edinburgh had it in stock (& in London they had never heard of it)
In reply to Douglas Griffin:
Thanks for posting; my collection of SMCJ doesn't go back that far. Lovely to see the photos of such a gorgeous day and to read the details of Adam's tour, which until now I only knew about in outline. It's interesting also how many different routes people have used to link the major Cairngorm tops, and which bits (if any) had to be ascended or descended on foot. Primitive bindings must have been quite a limiting factor in 1962.
