Following another period of heavy rain onto already saturated ground I thought it would be a good time to go out walking. While out on Smitham Hill came across an interesting double collapse in a depression (NGR ST 5545/5360).
One of the collapses was taking a substantial flow of water.
This collapse is approx. 2m diameter x 2m depth, within mostly clay material, no solid rock was noted.
The second, dry collapse is slightly higher than the wet sink and is possibly some indication of ‘passage’ direction, approx. 3m long x 2m width and up to 2m depth, water appears static.
