The depressions, some containing lakes, were created by the melting of blocks
of glacier ice. They became buried by glacial gravel deposited on the floor of a
meltwater stream that once flowed in a channel bordered by ice lying over the
lower ground on either side. Remnants of the original flat top of the deposit
are visible in the middle distance.
