Would a bentonite mine be a good EC?

Recommended Posts

Topic question. Would an active bentonite surface mine be a good earthcache? No idea how I would set it up yet, if at all.

Yes, if you can find a safe place to gather a sample that would be out of the way of the mining operation. You could illustrate the water absorption characteristic [hydrostatic head stabilization], historical uses [laxative, use in construction to oil & gas drilling mud], and the platelet particle shape that yields its sealant properties. Overall it’s worth a shot…

There are EarthCaches about mines, EarthCaches about clay, so this topic and location could work. However, please be mindful of access, safety, and land manager/permission issues, because the reviewer will definitely be looking at these things, especially since there is a mine involved. Best wishes -- Matt
