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 notes in the photos mark where a road or other public right of way crosses the 200-foot contour in the Afon Glaslyn catchment.
The numbers under each photo are date and Ordnance Survey grid reference in the form: yyyymmdd_easting-northing.
