that the occurrence of glacial traces beneath an overhanging rock
bordering a fissure at Dumbarton Castle is, amongst others, worthy
of being recorded.
The hard whinstone, which here rises up abruptly from the allu-
vial shores of the River Clyde, exhibits in a very interesting and
beautiful manner the crystalline and prismatic structure peculiar to
such trappean effusions, but the lines of fracture or divisional planes
of the Rock of Dumbarton are observed to inclhie generally at an
angle of about 70°, giving to the Rock on one of its sides a rather
precipitous and overhanging appearance. The effect of denudation
or abrasion has therefore been to wear or score it in certain parts into
fissures, the sides of which have a parallel inclination ; and across

a. Fissure.
the centre of the Dumbarton Rock there is one of considerable depth,
di\'iding the hill into two parts or summits, as shown in fig. 2.
It is on the sides of this fissure, which now forms a passage, and
the only mode of approach to the buildings on the Rock, that striae
and abrasions are observed, which constitute the subject of this notice.
The fissure intersects the Rock from south to north, pointing
directly up the valley of the Leven, through which in the distance
appears the lofty summit of Ben Lomond. The wall of rock on the

left hand or western side of the fissure about midway up the ascent.

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.
