Bohuntin Hill

Upon returning to the wee carpark at the bottom I was chatting to a walking couple who had similarly just arrived back at their car. London based holiday makers, they were impressed by the natural Glen Roy valley architecture, largely sculpted by ice and water over the last 12000 years.
I then explained how another walker I had chatted to here last year had compared it to man made bings at an iron ore mine in northern Sweden. The lady could see the town name had escaped me and she chipped in "Karuna".
"Yes that's right" and she could see how I was looking intrigued.

She explained she has instruments set up there (in a steel container) to measure upper atmoshere activity relating to the aurora. Above the arctic circle, the location lent itself to the data measurement she wanted to record. It was a fascinating chat. Much of the solar activity she spoke about (though way over my head) impinges on my own GNSS measurement.

By this time I had shared with them that the purpose of my walk today was to leave some of Caley's ashes at the top of Bohuntin Hill.

With still a few days left of their break they had other options for walks and the man took a map from his boot.  It was the OS explorer number 400 covering Glen Roy. I had totally forgotten until I saw it, the cover photograph features Caley at the summit cairn, where I had left his ashes half an hour earlier. I had to explain, with some difficulty, the significance of the image.
