Yes, a couple of nice pics, but how it's changed. I'm guessing they're 1950s not long after closure from the size of the tip and lack of vegetation. The steelwork of the screens building is still standing but is now well hidden by trees and scrub which cover the banks on both sides of the railway.
Known originally as Birkby Colliery the mine became the Birkby and Albright Colliery after the new drift opened in 1929 but was known locally as "Dearham Drifts". Taken over by NCB it closed in 1950. More confusing is that it lay midway between Dearham and Crosby while at Birkby itself the small private drift mine, closed 1952, was Ellenbank Colliery.
The Lonsdale Pit was in the middle of Dearham. It was last worked in the 1890s.
