Some cool upload photo images:
Narrowing the field - very recent coastal erosion at Skipsea, East Yorkshire
Image by Earthwatcher
Originally uploaded for the Guesswhere UK group.
Average coastal erosion rates for this part of the Holderness coast are in excess of 2.5 metres per year but sometimes a great chunk will go all at once. The main mechanism for the erosion is failure and collapse of the Skipsea Till (grey/brown in the photo) by rotational landslides. The slipped material is readily removed by the sea during storms and high tides, exposing a fresh cliff face which rapidly becomes unstable, eventually failing once more.
Rather good viewed large on black

Bullhouse minewater discharge into the River Don, near Penistone, west Yorkshire.

Originally uploaded as No.4 of a jolly selection of Guesswhere UK puzzles.
This is the Bullhouse colliery minewater discharge into the River Don at Ecklands, near Penistone, West Yorkshire.
The mine worked the Halifax Hard seam and was drained by a 'water drift' - a long straight tunnel on a gentle downward gradient - which had it's outfall in the banks of the River Don as in the photo. The mine was abandoned in 1915.
Since this photo was taken, the Coal Authority has diverted the minewater, pumping it to treatment works and settling lagoons in an old quarry nearby, before allowing it to return to the river.
