Lindley Hanson's List: Geologic Events

In order for the science of evolution to be properly understood as a science, with all its inherent characteristics and limitations, ENSI maintains that a substantive introduction to the nature of modern science is a necessary prerequisite. Be sure to take a look at those lessons on this site...they were intended to do just that.
Intended Audience/Grade Level These lessons are intended for use in any high school biology course. However, many can be used in middle school / junior high school, possibly with slight modification depending on teacher's style and approach, and the experience and level of students. Many would likewise be appropriate for use in junior college or lower division university levels.

The great continental ice sheets were melting very fast in the time of Glacial Lake Missoula, shedding great torrents of meltwater every summer, raising sea level an average of approximately 100 feet every 1,000 years. Meltwater swept enormous volumes of sediment just freed from the melting ice into every low place it reached. The glacial lakes got their fair share. All glacial lakes, ancient and modern, deposit distinctive sediments unlike those laid down in any other setting.
