Hikers near Marrow Creek have long reported an unusual echo effect — shouted words returning with what sounds like an extra syllable appended, one nobody in the group had said.
Our 2020 field visit recorded the phenomenon on tape twice, though acoustic analysis suggested a plausible mundane explanation: a rock formation upstream creating a secondary, delayed reflection that our recording equipment picked up as a distinct “extra” sound.
Case archived as likely explained, though the acoustic theory hasn’t been independently verified by a specialist.
