The rocks form fantastic shapes Off to buy our guides from the shop
Visit to Brimham Rocks with Yorkshire OUGS - Carboniferous deltaic sandstones sculpted by glacial action and wind First stop - the local "amenities" - incidentally, a magnificent view
Coarse sand grains - sub rounded, anyone? This is quite a famous rock
"DIY" - looking at grain sizes and thinking about deposition environments Nobody felt it was necessary to look underneath this to see what sort of rock it was!
Looking across to the moors My walking stick for scale
View over to the valley, scoured out by glaciers More sedimentary structures
Photographed through the hand lens Some of these layers also included iron, and small nodules of feldspar
Close up of sand grains - diagonal line is more resistant to weathering - silica cement? A last look at sedimentary structures before leaving
Looking down at the peaty water below "This high" - "This long" - ?
Next stop - How Stean Gorge Members finding interesting things?
Looking at the limestone walls of the gorge We didn't go through the "tunnel" with its 8m drop!
Clambered down to the gorge - very slippery! They have found something to look at
Eventually these link up and the gorge floor deepens Apparently where a highwayman used to hide out
Rounded potholes or moulins in the stream bed - rotary action of pebbles scour these Some hardy members tackled Tom Taylor's cave - torches needed!
My walking stick for scale Did I forget to mention there were bilberries?
Fossils in the limestone Best way to end the day - pancakes with bilberries picked at Brimham Rocks!
