stony fragments being deposited or imbedded in
this sandy gravel, just as the stones or boulders of
till and boulder clay are deposited or imbedded in
plastic clay.
But the stony fragments of this “ boulder sand”
are not, so far as I was able to examine them,
either striated or planed sufficiently to be identified
thereby as of glacial origin. They differ very
little, and that little only in a slight
subangularity, from freshly-broken rock fragments or
ordinary talus debris.
Regarding it as a whole, it may be described as
a fragmentary heterogeneous deposit of more or
less gritty sand, and angular or very slightly
sub-angular fragments of all sizes, from sand grains to
large blocks, all loose and deposited without
pressure, and with little evidence of long travel. These
lie pretty nearly as they might had they fallen on
the spot in showers from the sky.
What then is the probable origin of this
ambiguous deposit ? I regard it as the last legacy of
the dying glacier-fond ; its personal effects left
upon the spot where it expired, when the change
of climate terminated its existence.
A neve’ or sneefond like that which must have
covered the Dovrefjeld would receive the debris
