What technologies make it possible for us to understand the scale of changes that occurred as a result of the breaking of the glacial dam holding back lake Missoula's waters

Magnetostratigraphy, optical stimulation luminance dating

Explanation:

The Missoula floods were a glacial lake outburst that was across eastern Washington and created rapture of an ice dam on the Clark rover. According to the US geological survey scientist found evidence of mega 25 major floods were discharged about 10 cubic km per hour. Based on the presence of the multiple interglacial deposits that were embedded in the flood deposits. Techniques like the magnetostratigraphy, optical stimulation luminance dating were used to study and estimate the old floods of the Missoula's waters. The magnetostratigraphy is a technique used to date the volcanic and sedimentary sequences and thus identify the movement of rocks.
