Geocache Description:

Another Earthcache designed to remind cachers that Geology is all around them and not really all that difficult


Etymology

A wain is a cart, so a wainwright is a maker or mender of carts, not just a solitary walker, a fan of fish and chips and a writer of Guides to Lakedistrict Fell Walks
A gate is a somewhat antiquated name for a road or track, more common in Yorkshire than other counties. Therefore a waingate is a cart track or wagon road..

The materials

Until the buiding of the canals and railways, heavy goods of all types were transported by horse and cart; this slow and expensive process carried on in remote areas until the early sixties when the carts were drawn at greater speed by tractor. The wheels of the carts caused deep ruts in wet weather and eventually led to the need for repairs. In towns and cities roads were firstly covered by Cobbles, rounded blocks of local stone, and later as transport costs reduced in the railway age, by Setts which were shaped lumps of granite. Remote areas like Primrose Lane at GZ had to be repaired by whatever material was convenient and free or low lost.; the materials found locally were mainly Carboniferous Gritstone from the Millstone Grit and the Coal Measures, quarried locally. Larger quarried pieces were used for building purposes, and any spoil created by the process was used for drystone walling and track repairing.. Over the years other rocky materials were incorporated into these repairs, and, ignoring a few patches of concrete, three types of rock, coloured brown, white, and black can been identified at GZ Firstly the most local material probably originated in the disused quarry to the west of the Mellor Moor triangulation point. Secondly more recently used material is commonly sold locally having been transported from quarries in Derbyshire. The third material is considerably harder than the other two and has a far different origin having been transported from the north by glacier and left behind after the global warming of approx 15000 years ago.

Logging Requirements

Q1 Two of the rock types are sedimentary and one is igneous, identify by colour which is which.
Q2 Again identify by colour which is the hardest material. Why do you think this rock is harder?
Q3 The igneous rock is the oldest, describe its texture, rough/smooth, and does it show any crystal shapes?
Q4 Any idea what the igneous rock might be?
