Winchester is on chalk, this is not something you think of too often, apart from when the soil has been removed (Twyford Down/M3, general river bank maintenance etc), when the surface turns into a fiercely adhesive mud that could hold the insulation tiles onto the space shuttle.
I cycled through a patch once and it stuck to the wheel in a 2" thick layer- it looked as though if I could have kept going it'd have created a Swiss Roll style chalky-mud based dessert.
CSB WARNING!
