This route is climbed using ice axes and crampons. Chalk is usually too soft to climb using normal methods.

There's been lots of complaints about the damage that climbers do to the fragile cliffs by climbing on them in this way. The sea does a lot more damage through natural cliff erosion ! Ihave a feeling that this particular route has already fallen into the sea!

Limestone is a hard rock that is easily weathered into a surface full of holds which makes it fun to climb on. Notice the horizontal bedding planes and vertical joints.

This Pembroke cliff is situated within an Army firing range and so there are conflicts between climbers conservationists and the military.

Shale is a kind of fine grained mudstone. The rock with which this cliff is made of has been squashed by enormous pressure. Is it actually at a metamorphic rock?

The bedding planes are almost vertical - hang on I thought sedimentary rocks were laid down as horizontal deposits? Plate tectonics is responsible for the folding of these rocks!
