GILLIGAN : EFFECTS OF STORM ON BARDEX FELL. 387 
examination of the shales in the grit sliowecl evidence of much 
crumpling, in one place, at least, the beds being vertical. The 
grit along the line of fault is much crushed, and has wisps of 
Pendleside shale caught up in it. Furthermore, the Pendle- 
sides here show beautiful slickensiding along horizontal planes. 
Confirmation of what appears to be thrusting is found again 
lower down the fell side, where the beds are inclined 45° in the 
direction N. 60^ W. , and appear to have been packed up over 
the beds below, which are nearly horizontal. The direction of 
dip here is almost at right angles to the dip found near the fault 
in the shales of the grit series, and without very careful map- 
ping it is difficult to see clearly what has taken place here, but 
the evidence seems to point to thrusting in a direction from 
north-west to south-east. 
Gill Beck. — The lower part of this beck was swept quite 
clean to the rock floor, and at tlie new bridge only a few very 
large boulders had been left behind. Higher up the beck the 
debris had completely choked the channel, being piled up at 
a point where the course of the beck takes a sharp turn. A 
waterfall in Nelly Park Wood had been cut back about ten 
feet, and a well-defined fault clearly shown. The weirs con- 
structed by the Bradford Coi-poration had been much damaged, 
several of the huge blocks of grit forming the aprons of the weirs 
having been displaced, and the residuum lodge near Gill Beck 
Head completely filled with sand. 
Barde.n Beck. — This was the main channel for the water, 
which rose at least ten feet, as shown by the grass still clinging 
to the trees up to that height. Into tlie Upper Reservoir the 
water carried about 10,000 tons of material, and removed stones 
weighing 13 cwt. from the embankment to the bed of the stream 
below. Blocks of grit weighing from one to three tons had been 
cut from the banks and carried down stream. 
Small tributary streams which ordinarily carry very little 
water had swollen to such proportions as to carry away large 
stone bridges. The residuum lodge for the Lower Reservoir 
Avas choked with hundreds of tons of material, and into the 
reservoir itself the stream had swept about 30,000 tons of sand, 
forming a huge delta.
