There are also three very amateur (though decent equipment for the day) videos of the Crickley digs from the 80's up on Vimeo... https://vimeo.com/53436254.
It's no time team, but you get the idea.

I've walked the region several times, and know Crickley and Leckhampton well, but it's been years since I've been, and I managed to totally miss the Crippets long barrow on all occations. Methinks I'm due a re-visit. Do you know if that crazy Nuclear Defence Bunker on Greenway Lane is open to the public or not, would be great to have a mooch around that. Also, looks like there's a parking nightmare up on Crickley Hill Country Park, with loads of peeps getting fined £100 a time for some dubious reasons (like being scanned by the ANPR at the entrance, then the ticket machine not working).

Cool, these are my most-local sites. Went past Crippets on New Year's Day and was very sad to see new fencing between the bridleway and the edge of the wood. Looks like the previous tolerant attitude to access has come to an end.
