+Pork King Posted January 5, 2013 Share Posted January 5, 2013 Topic question. Would an active bentonite surface mine be a good earthcache? No idea how I would set it up yet, if at all. Quote Link to comment
+GEO WALKER Posted January 5, 2013 Share Posted January 5, 2013 (edited) 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… Edited January 5, 2013 by GEO WALKER Quote Link to comment
+GeoawareGSA1 Posted January 7, 2013 Share Posted January 7, 2013 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.
