Description

Karst features are ubiquitous across Michigan’s UP and are developed in Silurian dolostones. The goal of this research is two pronged: to understand regional groundwater flow patterns and grike genesis. In May of 2019 we plan to travel to the UP and take GPS points of sink holes and springs in the area, measure discharge rates, and map suggested flow paths of regional groundwater. We will also be expanding our database of dissolutional features, primarily grikes (dissolutionally enlarged joints). By measuring grike dimensions and orientation, collecting rock samples for petrographic and dissolutional analysis, and collecting weathering and humic material from inside the grikes, we will be able to expand our understanding of grike formational processes in the UP.
