Daahn a't'owd Mill
The cache, a camo-taped film canister, is hidden low down a few metres west off the footpath on the edge of a grove of fine mature trees adjacent to the partially derelict Greenholme Mills.
To reach the cache location: park either at N 53 54.957 W 1 44.698 on Iron Row or you may be able to find some limited space around N 53 55.009 W 1 44.799 taking care not to block any access. The latter is nearer the trailhead @ N 53 55.038 W 1 44.815 at the start of the signposted footpath.
From the cache location, you can continue down the track and alongside the goit to team mx's nifty GC4532Y: Lock Stock and Two Smoking Barrels cache and a little further to the weir and stepping stones.
Nearby Burley-In-Wharfedale, previously a small farm village, became established as a busy mill village when cotton mills were built in 1790 and 1811 alongside the river.
'Dramatic economic changes were occurring all over Britain in the latter part of the 18th century, and Burley did not remain isolated from them. What had been a domestic system of producing textiles was transformed by the introduction of water powered machinery for some of the processes'.
The Greenholme Mills used power derived from building a weir across the Wharfe in 1790. In 1833, 360 operatives worked in 
the mills, including some who had come as pauper apprentices from London.
In 1850, Fison and Forster, partners who had started in business in Bradford, bought the Burley mills, and converted them to worsted production. The earliest mill was demolished and all new work was concentrated on the Greenholme site. Numbers employed grew to over 700.
William Fison and his wife, Fanny, lived in the 1820s mansion at Greenholme, which had belonged to her father, Jonas Whittaker, the previous owner of the mill estate. The house was set in 50 acres of parkland.
Fison spent most of his working life in Burley, taking a paternal interest in all village affairs. Along with William Forster (the noted industrialist, philanthropist and statesman), he was responsible for setting up the Local Board of Health in 1854, starting the Mill School in 1856, building the Lecture Hall in 1868, and donating the Recreation Ground to the village in 1897.
Greenholme Mills were reputed to be the largest water powered mills in the country in the 19th century. Their main product was blue serge, used for military and police uniforms until the 1960’s. The mill eventually closed down in 1966 and gradually being derelict and dilapidated, except for sections which were leased out to local small businesses.
In 2015 plans were announced to develop the site for housing, a restaurant, creche and spa/gym.
