New venture drift -wast tip
"Howgill Colliery - Another early Thompson project was the Howgill Colliery which was a drift connected to the Blacksyke Branch near Forest Head. Howgill was closed in 1880 but sections of it were worked many decades later to help boost the dwindling coal resources. In 1919 the Naworth Coal Company was again considering fresh mining activities closec to the old Howgill Colliery and the Venture drift was reopened beside the Gairs Branch south of Forest Head which entered the Howgill seam this was called the New Venture Drift. At its peak in 1923 it employed 46 below ground and 16 on the surface and finally closed in 1934".
