Harrow bog, college valley,northumberland

Said to be the largest remaining area of original forest in the Northumberland National Park it can be found on the east side of the College Valley between Hethpool Mill and Southernknowe. It starts just a little beyond the water meadows to the south of Hethpool Mill.

The remains of the old farm are just a little up the slope to your left ( bottom of harelaw on the Newton Tors). This picture shows the remains of the farm and a view towards Hethpool in the distance.

 After crossing a small stream you come to a large deer fence which marks the start of the semi natural woodland and the continuation of the new eastern way footpath. Its extremely boggy and wet!

  There is an archaelogical report of the farmstead here

excerpts as follows

From this area a coin dated to 1789 was recovered from below the rubble collapse providing us with an approximate date (late 18th Century) for the abandonment, while a roof tile recovered from the same area suggests that the structure had a pan tile roof as apposed to a thatched roof.
