The White Ash brook is a small watercourse in Accrington, it flows through around 420m of culverts before joining with the Hydnburn brook.
I met with CameraShy and we dropped into the brook at the upstream infall. Initially the culvert was a small brick tunnel which had brick ends projecting out half way up.
A short section of modern concrete pipe lead to an older cut stone tunnel which the light from the outfall backlit nicely.
After a walk through the open air was the next infall, the water got deeper with each step and we'd soon breeched our waders. Luckily it got shallower again round the corner. This culvert too featured the half height regular projections along the along the length of the older bits.
