Soooooo this is a massive long shot........
April 2013, myself and my friend went our first hike of the year in most unexpected wintery conditions, (complete snow coverage), and managed to bury a set of freelander keys in about 8 foot of snow... yes - we were launching ourselves down the side of the mountain like children!
It's unlikely these keys will ever be seen again but it's worth a shot, now that I am on this site.
Thanks folks.
