A Walk at Water End…
Over several months in 2022 Liam Gallagher, an HGS member, visited Water End near Welham Green in Hertfordshire a number of times to gather information to update our records for this SSSI and to photograph the position of swallow holes at various times of the year under various hydrological conditions.
The geological aspects of the site are discussed in some detail here.
In addition a ‘self-guided walk’ around the site, with less geological ‘detail’ but with information on how to best access the whole of the site and how to enjoy the hydrogeology and geomorphology in a wider sense can be found here so you can enjoy the features of the Potterells Stream and Mimmshall Brook swallow holes ‘estate’.


Two videos support this walk:
