For a time the glacier&#039;s southward movement was balanced against the glacier&#039;s melt resulting in the deposition of sand and gravel, sort of a massive conveyor belt effect. At times big chunks of ice remained for a while as the sand and gravel accumulated around them creating what today we refer to as &#039;kettle lakes&#039;. This one is fed primarily by ground water and it&#039;s level fluctuates. Last year the water level dropped, exposing muddy flats ripe for new life. I was fascinated by this field of blossoms.<br />
