Of course you can see the weir from here, you're about 4m up a tree...thought it best to be clear from the outset. Also, take a pen or pencil up with you. Be aware of a concrete wall where a burn enters the river. Keep a look out and you won't fall.
Before the Tidal Weir was built to the east of Glasgow City Centre in 1901, marked by GC6H57Z, then this weir marked the highest point where Ordinary Spring Tides would reach on the River Clyde. The Tidal Weir is approximately 7 miles downstream from here.
This weir also served two mills. Clyde's Mill on the left bank near here was a corn mill. The Carmyle Mills on the right bank were grain mills according to the mid-1860s Ordnance Survey County Map of the area. At that time, the lands on both banks were predominantly farmed, though there were a few small coal pits and associated railway lines. The mills were still in existence during the First World War. The land to the south of the river here was developed with a factory being built here between the First and Second World Wars. If you continue along the river walkway heading upstream, the walkway uses the old embankment that carried the railway branch in to the factory from the railway line that crossed the river at the steel viaduct upstream. The land that was the factory is now home to the Scottish Fire and Rescue Service Headquarters and training facility.
In this area, the Clyde was crossed by a ferry immediately downstream of the weir or a ford, which was roughly where the Clydeford Road bridge crosses the river. The ford would still have been capable of being used until the Tidal Weir was built in Glasgow in 1901. In fact the 1898 Ordnance Survey County map for Lanarkshire still shows the ford, even though the Roseburn Bridge had been built a short distance downstream of the ford.
So that is why the cache is here. Now, where is the cache? Well, it is not at ground level. Nor is it reachable from ground level. Happy climbing.
Remember, just because a cache is there doesn't mean that you have to get it. Also, logs that say that you could see the cache but couldn't get to it? Well, that's not a find...
