See, that's the problem with a nebulous term. There are lots of ways to build a dam-- pile up dirt, use field stones (with some sort of sealant/mortar in the gaps), use sand bags, use bricks, use logs (again, with a sealant), use poured concrete... Let's say, for the sake of argument, hitting a poured concrete dam (like the Hoover) DOES make a hammer-- but hitting an earthen dam DOES NOT make a hammer. Okay, that has established upper and lower limits of hammerdom-- but at what point in the grade from dirt to concrete does the artificially-built dam become "artificial enough" to be concidered a hammerable object? When does the bloom become Michael's tomato? ______________________________________________ http://www.meteoritecentral.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
