Geologists Love To Showcase Their Sediments

No need to be either sentimental or a geologist to enjoy wry scientific humor with any of these gifts featuring the three different kinds of rocks as found in Grand Canyon, along with the scientific truism saying for all those in geology: "Geologists Love To Showcase Their Sediments". Make others do a double-take on any of these double-entendre word play gifts on the word "sedimental", which could mean "sentimental"! Educational science attitude for all who love the Grand Canyon!
