Summary[edit]

Description

SEDGWICK ON THE MAY HILL SANDSTONE.
217
through them. During a short visit to this locahty, in the month of
September, I met my friend John Ruthven, who had been some time
employed upon the task to which I have before alluded ; and I found
that he had already discovered some good characteristic Coniston
corals and shells among the watercourses near the top of the pass.
We then examined together some broken ground which has now been
cleared of wood ; and in several places (especially near a farm called
Bowerbank) we had access to the bare rock, which contained well-
known fossils (such as the Trinucleus Caractaci, &c.) of the Coniston
limestone and calcareous slates. The evidence was therefore now
complete.

1. Coniston limestone and shale.
2. Coniston flags.
3. Coniston grits.
4. Ireleth slates (=Wenlock).
5. Upper beds of the Great Scar limestone.
6. Limestone and shale in alternations.
7- Millstone grit series.
The facts here stated may seem too trifling to deserve notice.
They show, however, how true, in this part of England, nature
continues to her own type ; and they partially help to fill up, by a
good symmetrical section, that interval of ten miles, above mentioned,
between Helm's Gill and Thornton Beck. In the lower parts of
Barbondale, it would be in vain to look for the Coniston beds, because
unequivocally newer beds, about the age of the Wenlock shale, are,
by the great flexures of Middleton Fells, made to abut against the
line of fault. By a great reversed dip the Coniston grits are, how-
ever, again brought out on Casterton Low Fell ; and I think it just
possible that in the deep water-course on the south side of that Fell,
the Coniston beds may be hereafter discovered.
So far as I could make out from a very obscure section, the lowest
group (No, 1) is of very considerable thickness, and is made up of
dark shaly beds containing many bands so calcareous as almost to
pass into limestone. "Whether there may exist any well-defined bed
of limestone near the base of this group (as at Coniston), it is im-
possible to tell ; but the calcareous slates just noticed seem to en-
croach upon the Coniston flags (No. 2 of this section), which, at the
point here described, do not seem to be more than 400 or 500 feet
in thickness*.

  • Near Coniston the flags are, I think, full three times the thickness here
given.

Public domain

This work is in the public domain in its country of origin and other countries and areas where the copyright term is the author's life plus 70 years or fewer.

This work is in the public domain in the United States because it was published (or registered with the U.S. Copyright Office) before January 1, 1929.

This tag is designed for use where there may be a need to assert that any enhancements (eg brightness, contrast, colour-matching, sharpening) are in themselves insufficiently creative to generate a new copyright. It can be used where it is unknown whether any enhancements have been made, as well as when the enhancements are clear but insufficient. For known raw unenhanced scans you can use an appropriate {{PD-old}} tag instead. For usage, see Commons:When to use the PD-scan tag.
