Bowland 1500's

[wheezing donkey]

I read the sightingt owers on white hill were built int the 20th century to aid the construction of the hawswater aquaduct which runs under white hill. I run up there regulary and very rarely see anybody its an amazing place.

Correct, andyt. There are actually 3 of them ( all in a perfect line and shown on the OS 1:25,000 ); the 3rd is well to the N, over the convex brow. You need to be an ardent Bowlandologist to go looking for it. Seemingly the metal crossbar, across the top of the "flue" was used to clamp a sighting device ( theodolite? ).
Good effort Ian, for an "on-sight" visit to Bowland. I'm sure that I've mentioned it previously; the secret to fell top nav in Bowland is to know your fences and be able to recognise your fence junctions.
The gulls? If you look at the OS 1:25,000 map, you will see an area on the SE flank of Ward's Stone ( at the top of the Tarnbrook Wyre ) named as "The Gullery". They nest in that area between Ward's Stone, Wolfhole Crag and Brennand Great Hill, having spent all day scavenging on various municipal rubbish tips ( notably Salt Ayre between Lancaster and Morecambe ); hence why it is unadvisable to drink from Bowland becks.

As far as I'm aware there are 8 crash sites on the Bowland Fells. 3 or 4 years ago, one of our "more forensic" members organised a club run around all 8 in one day. Several wives and girlfriends / partners were quite alarmed at the duration of their abscence.
