This is a fabulous image of a marginal channel cut by meltwater near the edge of Fountain Glacier on Bylot Island. When it was abandoned, the marginal stream started to cut another channel some distance downslope. Probably this channel was used seasonally for a number of decades before being abandoned.......
Another abandoned ice marginal channel, this time cut in bedrock (to the right) and in glacial and glaciofluvial sediments (to the left)
The modern features shown above are similar in scale to a number of small channels on
the flank and summit of the Mynydd Preseli upland ridge.
