About as photogenic as the concrete dam at Cow Green Reservoir ever gets. [In my opinion, this is about as ugly as a dam can be, especially given the wild beauty of the moorland setting] The pass valve is set to discharge a minimum flow rate, to maintain the downstream river environment.

Looking down the lower part of Cauldron Snout [Yes, that really is the name of this waterfall / cascade] where the river cuts into part of the Whin Sill [Dolerite]. It is just below Cow Green Reservoir on the Upper River Tees, on the border of Cumbria and Co. Durham, in Northern England. Much of the area is protected as an SSSI. [Site of Special Scientific Interest - geology & flora in particular]. Part of the route for a long distance footpath "The Pennine Way" which follows the river here is just behind me.

Looking from the western end of the car park at the western end of Cow Green Reservoir over a short height dry stone wall - although the cap stones are cemented in place. This is the view as we eat our picnic lunch. Weather is sunny intervals, with a brisk wind. [You can see how low the water level has got, from the exposed foreshore in the middle distance, over the dry(ish) summer we have just had].

This was found below the normal water line at Cow Green [currently the level is well down] in a pile of similar stones. The substrate is smooth surfaced, but appears crystalline, mainly white and grey with some darker veins and patches. The "webbing" appears to be granular, almost sandy in texture and colour, but as it is much harder and resistant - perhaps by the cement between the grains, it is raised several mm in most places above the substrate. My limited knowledge of geology hasn't yet produced an ID for this specimen. Further research required.
