ROCK SOLID EVIDENCE
"What have you got for us, Che?" Steve questioned as he and Danny entered the lab. He pointed to the box of rounded rocks resting on the lab table.
"Well," the forensic scientist replied. "I took them over to a geologist friend of mine at the university. He ran several tests: type, mineral analysis, fossil content. You name it, he checked it out. You've got a mixture of types."
"They all look like ordinary rocks to me." Danny noted. "What's so special about them?"
Che picked up a couple of rounded, reddish grey specimens. "These are sedimentary. Their mineral content indicates that they come from New England, possibly the coast of Maine or Massachusetts." He indicated a small, round, speckled one. "This is granite. It's an igneous rock The ratio of quartz, feldspar, and mica and the size of the feldspar crystals places its origin somewhere in Canada."
"Igneous?" Steve questioned, "I thought igneous rocks came from volcanoes, like the lava that forms these islands."
"Granite is a batholithic igneous rock," Fong explained patiently. Seeing the confusion written across the two detectives' faces, he went on. "That means it formed from underground pools of magma. Given the mixture of specimens, I think they are from glacial deposits on the coast of New England."
"So," McGarrett broke in before Che decided to teach a class in freshman geology, "What does it all mean? Any other clues?"
"The box itself, Steve. Note the lettering on the lid, 'Souvenir of Cape Cod.' With all this evidence, I'd say you have a collection of Plymouth Rocks!"
