Under a couple of bridges and past where a path comes in from the road to the north. This can form part of a circular walk if you wish. The cache can be found on a rock shelf near the start of the dramatic limestone 'gorge'. Watch where you're putting your feet when seeking the cache.
"This is the Dalton Limestone Formation (350 million years old) that is exposed in the superb cutting in the Hincaster Trailway. The limestone here is in the middle part of the sequence where the sea floor was well below wave base. At times there was an input of muddy material and this can be seen in the cutting as shale partings (thin shale layers between the beds). Dalton Limestone generally is a grey well-bedded limestone that in places is very fossiliferous."

The tree canopy is now quite effective at blocking the light and it can be a bit dark and slightly spooky in the cutting! Is that the sound of a distant train? Look out for the long drill holes in the rock where the dynamite charge was inserted.
