Kame = Pile

Kettle and Kame Topography

Hard on the defunct gravel pit of the northwest side of the preserve is the deposit of glacial rocks washed to some extent by melting ice the former owners of the pit were turning over for profit with the averted result of destroying the water sources for the ecosystems of the future preserve.

The deposit is called a kame. Kames are the obverse of kettles, formed with an enormous remnant of glacial ice melts in place leaving a substantial depression. A kame is formed when earth gathers in a depression formed by meltwater running over a glacial surface. When the glacier melts (in this area the ice wash a mile high), the washed earth is left as a steeply sided pile we experience as a hill.

Water flowing beneath glaciers forms the long, ridged hills, eskers, we explored in yesterday’s post.

Also marked is a path for the primary esker, the bog formed by a kettle and another kettle that is now a pond. Click me to view a pdf file saved from GoogleEarth. It provides a clearer view of the header image.

  1. I taught 22 years in McCone County in eastern Montana. There was a dividing line in the middle of the county where the last glacial age had left evidence. North of the line, the glacial movement deposited tons of rocks. The farmers are still picking up rocks from their fields, and rock piles are numerous along the border of the wheat fields.
