Afon Colwyn

Trees, road and telephone pole with Post-it note attached.


When all the ice on earth melts, the average level of the sea will be around 200 feet higher than it is now. The Post-it note in the photo marks where a road crosses the 200-foot contour in the Afon Colwyn catchment.

The numbers under the photo are date and Ordnance Survey grid reference in the form: yyyymmdd_easting-northing.
