GA009	P805701	Burrington Combe. Bristol Excursion, April 17th 1919. A stream descending a swallow hole. This stream rises on Blackdown on the Old Red Sandstone and flows down in a northerly direction over the Carboniferous K beds which being of an argillaceous character are impervious but directly they reach the Z beds which consist of massive limestone with many joints the water immediately sinks in and finds an undergound channel.
GA009	P805702	Burrington Combe. Bristol Excursion, April 17th 1919. A stream descending a swallow hole. This stream rises on Blackdown on the Old Red Sandstone and flows down in a northerly direction over the Carboniferous K beds which being of an argillaceous character are impervious but directly they reach the Z beds which consist of massive limestone with many joints the water immediately sinks in and finds an undergound channel.
GA009	P805703	Burrington Combe. Bristol Excursion, April 19th 1919. The Rock of Ages. It was whilst taking shelter from a thunder storm in the 'cleft' of this rock that the Rev. Augustus M. Toplady of Blagdon composed the well known hymn 'Rock of Ages cleft for me'. He died in 1770 aged 38.
GA009	P805704	Burrington Combe. Bristol Excursion, April 19th 1919. Quarry in Carboniferous limestone. This consists of the massive oolitic and foraminiferal limestone of the Upper Syringothyris zone styled (C2). Added note: North, South.
GA009	P805705	Burrington Combe looking North. Bristol Excursion, April 19th 1919. This picturesque combe is a deep ravine cut into the northern side of the Blackdown plateau and shows a fine section of the Lower Carboniferous Limestone in the quarries on the left hand side of the road from Burrington. Owing to the high dip which averages 60 degrees, the whole of the beds from D1 to the Old Red Sandstone with a thickness of 2600 feet can be studied within two thirds of a mile. These are correlated to the Gully Oolite of the Avon section.

GA009	P805707	Cheddar. Bristol Excursion, April 19th 1919. As the Cheddar gorge mainly follows the strike we find that the greater part of the strata seen consists of the Seminula beds but the various horizons from C2 to D1 are represented.
GA009	P805708	Cheddar. Bristol Excursion, April 19th 1919. As the gorge runs south-westwards across the strata which are dipping due south we find on the right hand side a series of step like dip slopes and on the left mural faces and jointed bastions progressively increasing in grandeur as the valley deepens toward its outlet on the plain.

GA009	P805710	Cheddar. Bristol Excursion, April 19th 1919. The valley bottom is dry and without any stream but as we approach the village of Cheddar a stream is seen to issue from an arch in the limestone. Its course underground has not been followed but is probably fed some several swallow holes in the Mendip hills.

GA009	P805712	Cheddar. Bristol Excursion, April 19th 1919. Quarry in the Cheddar Gorge where the Great Rock fall of Feb. 6 1906 took place. This is in the upper part of S.1. Many fine specimens of the coral Lithostrotion martini are found here.
GA009	P805713	Cheddar. Bristol Excursion, April 19th 1919. From below these bastions assume the appearance of isolates pinnacles but they are for the most part spurs from the denuded arch of the hills.
GA009	P805714	Radstock District. Bowldish Quarry. 3/4 of a mile north of Midsomer Norton. Bristol Excursion, April 21st 1919. Sections in Lower Lias in the Sauzeanum zone. These beds are very fossiliferous and from this quarry the finest specimens of Spiriferina Walcotti have been obtained.

GA009	P805716	Radstock District. Clandown Quarry. Bristol Excursion, April 21st 1919. This quarry is in the Armatus and Jamesoni zones and consists of White Lias limestones overlaid by planorbis beds. The Spirifer bank and the conglomeratic and phosphatic band at the armatus raricostatus level are well marked and contain crinoidal remains and various marine fossils.

GA009	P805732	Aust Cliff. Bristol Excursion, April 22nd 1919. This cliff section exposed on the bank of the Severn at Aust shows in every detail the gradual passage from beds of Triassic age to those of the Jurassic system. The colour of these marls is due to the particular oxide of iron they contain. The Red marl having ferric oxide Fe2O3 while the green and blue have ferrous oxide FeO.

Added note:Tea Green Marls, Red marls.
GA009	P805734	Aust Cliff. Bristol Excursion, April 22nd 1919. The gypsum of the Red Keuper Marls occurs chiefly in the form of discontinuous vertical deposits like veins with which are connected smaller veins or strings ramifying through the surrounding rock. This mineral evidently fills up former cracks in the rock.

This mineral evidently fills up former cracks in the rock.
GA009	P805736	Aust Cliff. Bristol Excursion, April 22nd 1919. Step fault - formed by two juxtaposed faults 'throwing' in the same direction.
GA009	P805737	Aust Cliff. Bristol Excursion, April 22nd 1919. The gypsum which does not occur in regular beds is found in lumps, strings and veins through being deposited in cracks by percolating water.
GA009	P805738	Aust Cliff. Bristol Excursion, April 22nd 1919. Above theTea Green Marls occurs the well known Bone bed at the base of the Rhaetic or Penarth beds. At the south end of the section it consists of a dark hard compact limestone while in the centre it is a thin layer of siliceous grit loaded with fish teeth, scales, bones and dorsal spines together with vertebrae and coprolites of saurians. Above the bone bed are the black shales about a foot thick with Avicula contorta, Cardium rhaeticum and Pecten valoniensis. Added note:Tea Green Marls, Keuper Red Marls, Band with gypsum, Red sandstone resting unconformably on Carb. [Carboniferous] limestone.
GA009	P805739	Aust Cliff. Bristol Excursion, April 22nd 1919. The continuity of these beds are [is] broken by five faults in which the downthrow side is to the south. Down the lines of faulting are thin veins of gypsum and celestine associated with calcite, this together with the hardening due to the pressure of faulting causes a little promontory or buttress which projects for several feet from the cliff face.

Down the lines of faulting are thin veins of gypsum and celestine associated with calcite, this together with the hardening due to the pressure of faulting causes a little promontory or buttress which projects for several feet from the cliff face.
GA009	P805741	Aust Cliff. Bristol Excursion, April 22nd 1919. Immediately above the Avicula contorta zone is a thin argillaceous limestone known as the Insect bed. This forms the base of the White Lias beds while the top of the cliff is formed by the Lima Series of the Lower Lias. Added note: White Lias, Insect Bed, Planorbis Bed, Avicula contorta zone, Bone Bed,Tea Green Marls, Keuper Red Marls.
GA009	P805742	Aust Cliff. Bristol Excursion, April 22nd 1919. At each fault a small stream of water trickles over the face of the cliff. This is caused by the water percolating through the porous White Lias being dammed back against the marly clay below.
GA009	P805743	Spring Cove - Weston. Bristol Excursion, [no date, April 1919]. Remains of raised beach resting on Carboniferous Limestone (25 ft above high water). Added note: Talus, Raised beach, Carb. [Carboniferous] Limestone.
GA009	P805744	Spring Cove - Weston. Bristol Excursion, [no date, April 1919]. The raised beach consists of fragments of limestone with shells now living in the sea below and hardened by a calcareous cement. Added note: Talus, Raised beach, Carb. [Carboniferous] Limestone.
GA009	P805745	Spring Cove - Weston. Bristol Excursion, [no date, April 1919]. Bed of basaltic lava interbedded in the syringothyris beds (top of C1) of the Carboniferous Limestone. Added note: Basaltic lava, Laminosa Dolomite (C1), Calc Tuff.
